The internet is an interconnection of several millions of computers of different types of belonging to various networks across the globe. Internet is a networks that consists of million of private, public, academic, business and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies.  It is created by connection of many related different networks of computer. Currently the internet has more than billions users globally and the number is growing rapidly. More than 140 countries are linked to transfer for exchange of data, news, proposal, thesis, graphics, sound, software, video, opinions etc. now a day commercial organization began to run internet business (e-commerce) in the whole world in to a global village. Today, the Internet has entered the public consciousness as the world's largest public data network, doubling in size every year.

Only this not it is also advanced technology to earn money. It's a part of life now. Most of traditional communications including telephone, film, music, television are reshaped by internet. A managed software service optimized for Internet connectivity. It allows users to access their files and desktop applications through the Internet. Nowadays all animal, man, and living and non living things are included in the internet. All office, organization, company and all country use it to work and save their document on it so that, it is most important. Friends we are also known in the internet there are several libraries are available on the internet called online libraries which they can refer to get material on their subjects. In the domain of education and training, learning through the internet has become very popular and it is called online learning or e-learning. For others the internet offers several sites from where they can buy and sell products. For children, besides information and stories, the internet has several online games that they can enjoy. With internet came a new idea. There were many who realized that it could be used to start a new business. You all know that to start a business you need a lot of money. But the internet venture is not expensive. And internet gives service as Voice Over Internet Protocol (VoIP) and IPTV. And it accelerated new forms of people interaction through instant messaging, internet forums, and social networking and financial services. First researched about internet in 1960s, when a limited number of computers were connected in the United States to form ARPAnet. In 1990s an international networks resulted in its popularization every aspect of human life. The Internet is allowing greater flexibility in working hours and location, especially with the spread of unmet red high-speed connections and web applications. The Internet can now be accessed almost anywhere by numerous means, especially through mobile Internet devices. Mobile phones, data cards, handheld game consoles and cellular routers allow users to connect the Internet from anywhere there is a network supporting that device's technology. Internet is a short form of the technical term internet work The Internet is also often referred to as the Net. The Internet is allowing greater flexibility in working hours and location, especially with the spread of unmet red high-speed connections and web applications. And we are most popular internet is also connected with social work , interaction and activities, and organizing some of social networking website are such as Facebook, Twitter, Myspace, they have created new ways to social interact.

Many more people use the World Wide Web to access news, sport report, to plan and book vacation and to find out more about their interests. We use chat messaging and email to make and staying touch with friends world wide. As a result of the vast expansion of subscribers to Internet services, many more of the participants’ close family and friends were likely to have obtained Internet access at home.

Most printers have an online button you can press to turn the machine online or offline. Users are considered online when they are connected to a computer service through a modem. That is, they are actually on the line.





Internet Is Form Of Communication(New Media)



We can say internet is the source of information through information technological device. We live in rapid technological change. Everyday we are flooded with information from everywhere. The internet is sure that we are not left behind in terms of information on any front. Nowadays we want to any new information immediately. It is possible by Internet. Internet is the best way of media in modern period.

Well we know communication means sharing of information. Whenever we communicate, we share information, ideas and even feeling. Another important point is that any communication is not complete unless there is a feedback. It means whenever we talk to someone or someone reads what we have written, there must be a response from the other person. So in internet have feedback systems in place. In internet we share information or news by using narrative style and use of multimedia. An internet is very fast so we don’t have to wait for one full day to read and known day’s events in newspaper e.g. at 4 o’clock in the evening, if we want to check out the latest cricket scores, we have to simply log on the internet and check new website that will flash the information that we are interested in knowing. So internet is very popular for every human being.
Since, people read website in-between work they expect a language that they can easily understand. That’s why new media uses a narrative style or story format so that readers can easily understand whatever is being communication to them. The use of multimedia is also meant of facilitate the communication process. In new media language and multimedia package are both designed to act as interest factors.

Advantage:
Internet is also a very important mode of communication that we can not have ignored. We know that almost every organization today has a website. Anybody who wants to know about an organization will simply log on to the internet and check their website. So most of the benefits are most likely contains most of the information that anyone would want to know.
And Most of the television channels also have their own websites. Essentially, these websites are meant for information. A person can log on to the website of any television news channel and find out the different programs.. A website is also an important feedback vehicle. Viewers can log on to the website and give their feedback and comments about any programs.
We get access of visuals, pictures and words at a time. And we can share our feeling and emotion.
Limitation:
But you think everything is good about form of communication in internet (new media)? Not really, just as all things have their own limitations. These have also some disadvantages.  The most important issues here is that if anybody can write a blog and it is put up without any editing on the internet, then someone who wants to play trouble can always put up something on the internet that may have unfavorable effects.

Social Impact On Internet


Nowadays, most important part of social life is internet. We used internet various form and various types. Today internet has already established a essential role in teenager’s social life. For many families the internet is still breakable medium experienced as unfamiliar. Parents are developing strategies to manage and regulate the internet within the home framed by educational aspiration for their children. Children prefer online entertainment like media-music stars, sports, television programmed.
At that time Internet use in everyday life. It is longer multidimensional process of social change- in the family and childhood, in the leisure and lifestyle, in work and education in social value. This new period used the internet for communication and for information and generally experienced overall positive effect of using the internet on communication with friends and family, community involvement and psychological well being. 21st century the first generation is raised with wide increase availability of internet connectivity. Bringing consequences and concerns in areas such as personal privacy and identity and distribution of copy right materials. A social compensation hypothesis predicts that those who are reserved or lack social support would profit most from the using internet. More and more people have satisfactory relationship using the internet could interferer with their real-world relationship. It is possible that people with strong local relationship might turn way from family and friends if the use of internet for social interaction. With the rapidly expanding reach of the internet into most aspect of everyday life, we need to understand its social impact and the behaviors leading to this impact. Over 6 million people use blogs or message boards as a means of communication and for the sharing ideas.

Many people use the World Wide Web to access news, weather and sports report, to plan and book vacation and to find out more about their interest. Today many more social networking websites such as Facebook, Twitter and MySpace have launched. New way to socialized and interact. These networking sites user are able to add a wide variety of information to pages, to follow common interest and to connect with others. It is also possible to find new existing friends, to allow communication among existing group of people. People who use the internet greatly report more social support and more in person visits with family and friends. People use the internet in different way. Use of internet encourage or discourage social engagement. Using email leads people to spend more time online, encourages their use of the internet for information, entertainment and shopping. If communication is so important to internet users there is good reason to expect that the internet will have positive social impact. Communication including contact with neighbors friends and family and participation in social group. Affects peoples leave of social support their of having fulfill personal relationship, their sense of meaning in life, their commitment to social norms and to their communities and their psychological and physical well-being.
Through its use for communication, the Internet could have important positive social effects on individuals, groups, organizations, communities, and society at large. Broad social access could increase people’s social involvement, as the telephone did. It also could facilitate the formation of new relationships, social identity and commitment among otherwise isolated persons, participation in groups and organizations by distant or marginal members, and political draft. The Internet has positive or negative social impact, however, may depend upon the quality of people's online activities and what they give up to spend time online. Stronger social ties generally lead to better social outcomes than do weaker ties using the Internet might have disrupted this group’s existing social relationships. When more of the population was online, their use of the Internet for social communication might have led to more positive effects. The sample was suitably large to permit an analysis of the impact of individual differences in extraversion, social support, and age on outcomes, and of the possible differences in use of the Internet that could explain different outcomes.
 As new Internet communication services arise—instant messaging, chat rooms, multiple-person games, auctions, and myriad support groups—they become instantly popular. People use chat, messaging and email to make and stay in touch with friends and sharing common interest with each other in worldwide. more use of the Internet was associated with mainly positive outcomes over a range of dependent variables measuring social involvement and psychological well-being—local and distant social circle, face-to-face communication, community involvement, trust in people, positive affect, and unsurprisingly, computer skill. On the other hand, heavier Internet use also was associated with greater stress, less local knowledge, and lower desire to stay in the local area. In general, having more social resources amplified the benefits from using the Internet. Further, even if people use the Internet to talk with close ties, these online discussions might displace higher quality face-to-face and telephone conversation. .
As a result of the vast expansion of subscribers to Internet services, many more of the participants’ close family and friends were likely to have obtained Internet access at home. Similarly, the services offered online changed over this period. More news, useful health, financial, hobby, work, community, and consumer information, new synchronous communication services such as instant messaging, and online shopping became widely available.








IP Address


We are use internet different way in different work. In internet IP address is most important and most attractive part or we should not connect internet without IP address or IP address is a fascinating product of modern computer technology designed to allow one computer (or other digital device) to communicate with another via the Internet. IP addresses allow the location of literally billions of digital devices that are connected to the Internet to be pinpointed and differentiated from other devices. In the same sense that someone needs your mailing address to send you a letter, a remote computer needs your IP address to communicate with your computer. IP address supply for general host identification when communicating with other network devices using the TCP/IP procedure it purpose in IP networks. Typical (IPv4) address consists of four octets. For proper addressing the router also needs the network mask value, id set which bits of the complete IP address refer to the address of the host, and which – to the address of the network.
In other words IP address is an Internet Protocol address. An Internet Protocol is a set of rules that administer Internet activity and facilitate completion of a variety of actions on the World Wide Web. Therefore an Internet Protocol address is part of the methodically laid out interconnected grid that governs online communication by identifying both initiating devices and various Internet destinations, thereby making two-way communication possible. The network address value is calculated by binary AND operation from mask and IP address values. It’s also possible to specify IP address followed by slash “/” and amount of bits assigned to a network mask. In most cases it is enough to specify the address, the net mask, and the interface arguments. The network prefix and the broadcast address, the net ask, and the interface argument. The network prefix and broadcast address are calculated automatically. We can not have two different IP addresses from the same network assigned to the router. Unnumbered interfaces can be used on serial point-to point links, e.g. MOXA or Cyclades interfaces. A private address should be put on the interface with the network being the same as the address on the router on the other side of the p2p link (there ay be no IP on that interface, but there is an IP for the router). An IP address consists of four numbers, each of which contains one to three digits, with a single dot (.) separating each number or set of digits. Each of the four numbers can range from 0 to 255. This is known as "dotted decimal" notation. Example: 000.000.000.000

IP addresses can be either static or dynamic.
Static IP addresses: - Static IP addresses never change. Manually assign to the interface by a user. They serve as a permanent Internet address and provide a simple and reliable way for remote computers to contact you. They are generally preferable for such uses as VOIP (Voice over Internet Protocol), online gaming, or any other purpose where users need to make it easy for other computers to locate and connect to them. . Static IP addresses reveal such information as the continent, country, region, and city in which a computer is located, the ISP (Internet Service Provider) that services that particular computer and such technical information as the precise latitude and longitude of the country, as well as the locale, of the computer. Easy access can also be facilitated when using a dynamic IP address through the use of a dynamic DNS service, which enables other computers to find you even though you may be using a temporary, one-time IP address. This often entails an extra charge, however, so check with your ISP.

Dynamic IP addresses:-  dynamic IP address are temporary and are assigned each time a computer accesses the Internet.  it is automatically assigned to the interface by established  ppp, ppptp, or pppoe connections. They are, in effect, borrowed from a pool of IP addresses that are shared among various computers. Since a limited number of static IP addresses are available, many ISPs reserve a portion of their assigned addresses for sharing among their subscribers in this way. This lowers costs and allows them to service far more subscribers than they otherwise could.

Static IP addresses are considered somewhat less secure than dynamic IP addresses, since they are easier to track for data mining purposes. However, following safe Internet practices can help mitigate this potential problem and keep your computer secure no matter what type of IP address you use.















Use Of Internet In Modern Period


Nowadays internet is very important part of life. Internet is whenever and wherever you want. That means internet is necessary of everything. In the modern changing world, in daily practice, professionals and volunteers have to communicate with desperate people with respect and in cooperative manner.

The people can exchange information and might ask for each others help or support. The Internet can now be accessed almost anywhere by numerous means, especially through mobile Internet devices. Mobile phones, data cards, handheld game consoles and cellular routers allow users to connect to the Internet from anywhere there is a network supporting that device's technology. Within the limitations imposed by small screens and other limited facilities of such pocket-sized devices, services of the Internet, including email and the web, may be available. The Internet in general and the World Wide Web in particular are important enablers of both formal and informal education.

Although the Internet in recent years has been pictured as a cloud or has been referred to this way because of its hugeness and intangibility, it is actually very physical, with three major elements. On the one hand, it is composed of a very big amount of access and network hardware—PCs, wireless devices with Internet access, routers, servers, mass storage devices, cable or telephone access lines to homes and businesses, fiber optic cable for long-haul transport, network management equipment, and other hardware.
Communication through the Internet appears to be especially important for the labile or mentally ills because they have a chance of ending emotional closeness and lack of involvement simultaneously. People belonging to the suicide newsgroup seem to be very familiar with the idea of self-destruction; they are more rebellious, less dependent and are characterized by greater ambivalence and more-or-less serious suicide ideation. They cannot be reached and helped easily in the traditional professional manner. The present study provides a completely new data set, a new source of information on the Internet, which the author has explored and investigated. Through this survey suicidal people—who have not been available for any research—could be investigated. The results of the authors study might provide help distinguishing the suicidal and the non-suicidal (normal, or depressive and anxious) people from one another and understanding their communication and the underlying psychological mechanisms. There are additional opportunities for the members to communicate directly with one another, namely the chat forum and the e-mail connection. In the present content analysis, formal, syntactical and grammatical characteristic features, as well as speech patterns and verbal expressions of randomly selected samples from the conversation group, were compared with the samples of the other three groups in an attempt to found interpretable differences and similarities.  The development of modern technology or internet and its shade in our daily lives have been growing significantly in the modern period.

Business On The Internet

With internet came a new idea. There were many who realized that it could be used to start a new business. Internet has become central to social and economic life and is. It has changed the way firms find customers, customers find information, and people manage social relationships. The Internet is not just a resource for large corporations: it has created record opportunity for growth among small businesses and individual entrepreneurs. The Internet has made possible greater social and economic inclusion. Some of the jobs created by the Internet, particularly e-selling, publishing, and instant-messaging-based customer services, are not necessarily office-based, a advantage to the home-bound or people who need or desire flexibility between their home and work lives.
The Internet of today exists largely because firms pay its costs in exchange for the benefits of an advertising, marketing. Now the Internet is more than a medium of commerce. It has produced large social consequences, very different in scope and scale from those of television. It is a communications and a platform, and, consequently, its benefits are broad and open-ended. Internet is more than a medium for promoting products and services. E-commerce websites serve as a storefront, point-of-purchase stimulus, and sales venue.
 
Consumers can see a product promoted and, if they choose, buy and own it immediately. After a few seconds’ download of songs, movies, or books, they can consume the product online. The Internet economic activities using electronic networks as a medium for commerce or those activities involved in both building the networks linked to the Internet and the purchase of application services such as the condition of enabling hardware and software and network equipment for Web-based online retail and shopping malls (or e-malls). It is made up of three major segments: physical (ICT) infrastructure, business infrastructure, and commences, travel, financial products, electronic hardware, office products, and myriad other goods is sold over the Internet to consumers and businesses. Businesses have been very heavily invested for years via the Internet and pay by electronic funds transfer. Customers are conducting all business electronically as well. The advertising-supported Internet refers largely to all activity on the Web projected to promote marketplace exchange of products, services, or information. The combination of information and communications technology (ICT) in business has revolutionized relationships within organizations and those between and among organizations and individuals. Specifically, the use of ICT in business has better productivity, encouraged greater customer involvement, and enabled mass customization, besides reducing costs. Internet commerce is a powerful tool in the economic growth of developing countries

E-commerce:-  E- Comers Is the application of Information and Communication Technology to any transactions. Electronic commerce or e-commerce refers to a wide range of online business activities for products and services. Any form of business transaction in which the parties interact electronically relatively than by physical exchanges or direct physical contact. E-commerce is usually associated with buying and selling over the Internet, or conducting any contract involving the transfer of ownership or rights to use goods or services through a computer-mediated network. In other words E-commerce is the use of electronic communications and digital information processing technology in business transactions to create, transform, and redefine relationships for value creation between or among organizations, and between organizations and individuals.
The Internet economy is a broader concept than e-commerce and e-business. It includes e-commerce and e-business. E-commerce, not a part of the original Internet, has been one of the dramatic success stories. It offers several efficiencies for the consumer in shipping and delivery compared to bricks- and-mortar retailing, and has an immediacy of access and potential for deeper and richer display than catalog marketing, its closest analog. E-commerce has proven to be an important area of small-business creativity and participation. E-commerce sellers usually can offer discounts to consumers because they are saving on the costs of running a retail store. Additionally, e-commerce sites and company websites collect data about customers and future customers. They perform an interactive advertising function equivalent to sales forces. So, too, do e-mail solicitations, another form of interactive advertising on the Internet.
The major different types of e-commerce are: business-to-business (B2B); business to- consumer (B2C); business-to-government (B2G); consumer-to-consumer (C2C); and mobile commerce (m-commerce there are at least three major forces fuelling e-commerce: economic forces, marketing and customer interaction forces, and technology, particularly multimedia convergence


Internet Marketing



   

 Today business is the most important part of money income in world wide we do business in various types. In business we make money by exchange any goods with money or money product. Business linked all over the world. We are also known this is time for money making. World people want to make money more and more with spend less time period.

Nowadays internet business is most popular in the world.  Market is a group of potential customers with similar needs who are willing to exchange something of value with sellers offering various goods and service. That is ways of satisfying those needs. In modern period more people are buying and selling goods from internet. Internet marketing or internet based market is defined as the use of the internet and related digital technologies to achieve marketing objectives and support the modern marketing concept. These technologies include the Internet media and other digital media such as wireless mobile media, cable and satellite. Internet marketing is considered to be wide in scope.  It is also includes marketing done via e-mail and wireless media. In practice, Internet marketing will include the use of a company web site in conjunction with online promotional techniques such as search engines, banner advertising, direct e-mail and links or services from other web sites to acquire new customers and provide services to existing customers that help develop the customer relationship. However, for Internet marketing to be successful there is a necessity of integration with traditional media such as Print and TV, and this will be a consistent theme in this book. Marketing consists of individual and organizational activities that facilitate and expedite satisfying exchange relationships in a dynamic environment through the creation, distribution, promotion and pricing of goods, services and ideas. 

Internet marketing is cheap when groping the ratio of cost to the reach of the target audience. The nature of the medium allows consumers to research and to purchase products and services suitably. Therefore, businesses have the advantage of appealing to consumers in a medium that can bring results quickly. The strategy and overall effectiveness of marketing campaigns depend on business goals and cost-volume-profit analysis. The advertisers can use a variety of methods, such as pay per impression, pay per click, pay per play, and pay per action.


E- Marketing  
We do E-marketing from internet. The term ‘Internet marketing’ tends to refer to an external angle of how the Internet can be used in conjunction with traditional media to acquire and deliver services to customers. An alternative term is e-marketing or electronic marketing that can be considered to have a broader scope. Since this refers to the internet, interactive digital TV and mobile marketing together with other technology approaches such as database marketing and electronic customer relationship management (CRM) to achieve marketing objectives in internet. It has both an internal and external perspective considering how internal and external marketing processes and communications can be improved through information and communications technology. Achieving marketing objectives through use of electronic communications technology as with many terms with the ‘e’ prefix, we need to return to an original definition of the topic to more fully understand what e-marketing involves. E-marketing means using digital technologies to help sell goods or services. These technologies, like e-mail and websites, are a valuable complement to traditional marketing methods whatever the size of your company or your business model.
Benefits: It is no exaggeration to describe e-marketing as a revolution for the marketing industry. For the first time, it gives businesses of any size access to the mass market at an affordable price and, unlike TV or print advertising, it allows truly personalized marketing. Specific benefits of e-marketing include. E-marketing lets you reach people who want to know about your products and services directly – you don’t have to wait until they come home from work and switch on the TV or open their mail. People have a different, more personal relationship with most new technologies. For example, many people take mobile phones and PDAs wherever they go, and a surprising number feel lost without their e-mail. Combine this with the personalized aspect of e-marketing, and you can create very powerful and targeted campaigns. If you have got a website, then your customers are only ever a few clicks away from completing a purchase. Unlike other media which require people to get up and make a phone call, post a letter or go to a shop, e-marketing is seamless. The change from reading an e-mail to buying on a website is negligible – no special effort is required, meaning that your call to action can be much more direct. Together, all of these aspects of e-marketing add up to one thing: more sales. E-marketing lets you create interactive campaigns using music, graphics and videos. You could send your customers a game or a quiz – whatever you think will interest them. One of the great successes of e-marketing has been film companies letting people download trailers for forthcoming movies. Other small companies have picked up this idea – a radio controlled car company sends customers designs or photos of new products in development while clothing companies send out sneak previews of the new season’s range.  

The internet is used for marketing research to find out customers needs and wants. From internet marketing a key of success factor is achieving customer satisfaction or not. Through electronic channels and researching particular type of customers are using innovations of the internet. Internet marketing differs from conventional marketing communications because of the digital medium used for communications. The Internet and other digital media such as digital television, satellite and mobile phones create new forms and models for information exchange. Marketing message is broadcast from company to customer and other stakeholders. During this process, there is limited interaction with the customer, although interaction is encouraged in some cases such as the direct response advert or mail-order campaign on the Internet.

  1.  The Internet-based surveys are faster that means very high speed, vast resources, and its ability to directly communicate with others are its greatest benefits.  Because the Internet uses the quickness of computers to transmit its data, information can travel at amazing speeds. Speed is not the only benefit.  The Internet uses hundreds of thousands of computers all connected to each other to store vast amounts of information.  And finally, because the Internet allows for individuals to have specific electronic mail addresses, people can easily communicate with one another.
  2. The Internet is considered by many to be superior to the best and biggest libraries in the county.  This superiority exists primarily due to the thousands of organizations, companies and individuals publishing on the Internet.  With such ease of publishing and the wide variety of publishers, there is almost no subject left off the Internet.  The Internet's ability to deliver this vast amount of information has drawn even more users.  People not have to wait a long time for a reading book, newspaper, or magazine publisher to review and send an author's manuscript to a printing press to be bound or printed eliminates the time it would normally take to publish something.  Some events which are doing after some days they can be published on the Internet instantly.  A worldwide breaking news event can be published almost immediately. This part of the Internet alone has helped make the Internet a technological breakthrough. So internet is the greatest part of new media.
  3. Even finding not so current information can be a breeze using the Internet. Driving to a library and searching for possibly hours just to find some specific information is a task many of us have experienced.  With the Internet you can sit in the convenience of your home and search to find information faster than going to a library.
  4. Theoretically, the information on the Internet can travel at the speed.  Realistically, we know that this speed is nearly impossible due mainly to the large number of people using the Internet, and the limitation of the phone system.  However the Internet's speed is much faster than traditional means of gathering news and reporting information.
  5. Communication is a huge benefit of the Internet.  Many people use the Internet to simple send messages and nothing else.  Whether it is by news groups, chat rooms, or the most popular method E-mail, communicating over the Internet has developed vast appeal and usage.  Billions of people around the globe use E-mail to communicate everyday.  They all place great value on the convenience of sending and receiving E-mail.  I am really one of its biggest fans.  E-mail can be sent and retrieved by its recipient almost instantly.  The message never has to be printed or physically mailed to get to its destination.  Furthermore, the cost is considerably less than a postage stamp and is delivered a lot faster.
  6. With the invention of the Internet phone, some people can now even talk across the Internet just like on a voice phone but without paying long distance charges. When we want to send letters by post office it takes long time but use of internet or send by E-mail it is very fast or immediately.
  7. If you take social networks (such as facebook), these allow young people to communicate with each other, to keep in touch and even to get help. 
  8. The digital connectivity is the saving of natural resources and reduction in environmental pollution




Disadvantage of The Internet


.
There are thousands of pornographic sites on the Internet that can be easily found and can be a detrimental factor to letting children use the Internet. Very serious issues concerning in the Internet. We really known about every thing have many positive things and many negative things. Absolutely some limitation about the internet there are as follows:
  • The internet is unable to reconcile the whole world to decide what is good and what is not. 
  • The internet is limited by its bandwidth. In regular applications this is negligible but in bigger       commercial applications or in sub-developed countries the bandwidth is a major issue.
  • The internet is also limited to the IP addresses, at this time there is a sufficient amount IP address but the demand is ever increasing rapidly.
  • The information available on the internet is not always verifiable as users may edit and alter the perceived reality as they see fit altering articles, photos and even videos.
  • Network structural design, Quality of service, Language development and wired internet are also limitations.
  •   Even though the internet has in many ways brought the world closer together it has in many other ways caused a lot of damage to relationships and growth of individuals. Chat rooms and forums or other ways of interactivity cannot really replace real life socializing and if that takes place internet can be quite detrimental. Most of the cases of chatting or sharing feelings or emotions are fake relation. When we are uses internet relation every time, face to face interaction is also decrease. Hamper in private life and gap in personal relation and low satisfaction.
  • Misuse our personal information by another user: - Internet has made life easier for human being in many ways. But another way it through existing number of problems. Very large amount of information are freely available in the internet so when we using our personal information such as name, address, bank account number, etc. there are possibility to access by other user to make very serious problems in our personal information.
  • Virus danger:-
    Virus is nothing but a program which damaged the normal operation of our computer systems software that can slow the computer. Computers emotionally involved to internet are more flat to virus attacks and they can end up into crashing our whole hard disk. . A very serious issue relating to the Internet.
  • There are thousands of pornographic sites on the Internet that can be easily found and can be a detrimental factor to letting children use the Internet.
  • Internet is that has allowed a felling emotion and information are sharing with large amount of people who may access the different websites, forums and chat rooms are available. So these sites are disadvantage for loss time. And violence their faith.
  • Very serious problems that internet has created of spamming. Spamming refers to the transfer or sending unwanted emails and other links are sent in large size to people. These  informal size emails and these may contain viruses that may damage the system and even if they don’t cause any harm these can be plain exasperating
  • The internet is particularly attractive for a child since it has so much to offer in terms of entertainment. However pornography is a serious threat in today’s world and this can cause a lot of problems in terms of emotional and mental well being of the child. There are practically millions of pornographic sites and without supervision a child can easily fall into the trap of accessing such sites. Even though a number of informative sites are available there is also a darker side to the internet with the availability of a large number of other problematic sites that can cause serious effects on a child during these impressionable ages.

Networking


It is time for technological period and technical line. We are used networks for different way in different purpose. Networking as a designed to meet new people or connected together to share or exchange information and cooperate. World people are most popular about networking at that time. Simply we uses various types of networks everyday and every moment like as: when we get cash from ATM machine, or when we pick up or dialed mobile phone or land line phone, we are using some type of  networks properly. Networking is an important skill for mostly business people. In the world of computer networking is the practice of linking two or more computing device together for sharing time, sharing data. Networks are built with a mix of computer hardware and computer software. Networking functions make available the chance to expand our contact list, mostly when we create quality relationship. Networking is today considered so vital that its hard to conceive of an organization with two or more computers that would not want to connect them together. In other word network is simply collection of computers or other hardware device that are connected together, either physical or logically, using special hardware and software. Networking is the term that describes the process involved in designing, implementing, improvement, management and otherwise working with networks and network technologies. Networks consist of two or more computer that is linked in order to share source as (such as printers and CD-ROMs) exchanged files or allow electronic communication. The computers on computers on networks may be linked through cables, telephone line, radio waves, satellites or infrared light beam. In this time network are world wide and networks are everywhere. Internet has also revolutionized lives of millions in a variety of way even in the real world.
There are basic types of networks include in LAN, MAN and WAN.
Local area network (LAN): A network is said to be Local Area Network (LAN) if it is confined relatively to a small area. It is generally limited to a building or a geographical area, expanding not more than a mile apart to other computers. LAN configuration consists of:
                          A file server - stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network.
                          A workstation - computers connected to the file server (Mac or PCs). These are less powerful than the file server
                         Cables - used to connect the network interface cards in each computer.
   Metropolitan Area Network (MAN): covers larger geographic areas, such as cities. Often it is used by local libraries and government agencies often to connect to citizens and private industries.
  Wide Area Network (WAN): Typically reach across a single home, whereas wide area networks (WANs), reach across cities, states, or even across the world. It connect larger geographic areas, such as London, the UK, or the world. In this type of network dedicated transoceanic cabling or satellite uplinks may be used. The Internet is the world's largest public WAN.

Networks allow people and machines to communicate, using a number of services. The distance problem is solved by using a network, such as the telephone network with modem. Modern networks have more than the physical and the data link layers. The network layer is a set of mechanisms that can be used to send packets from one computer to another in the world. Mostly there are two type of networks:-
--packet switching:- packet switching, data packets can be carried together on the same link. They are differentiated by addressing information. Packet switching is the basis for all data networks today, including the Internet, public data networks such as Frame Relay and even ATM. Packet switches have queues.
--Circuit switching:- is the way telephone networks operate. A circuit emulates the physical signals of a direct end-to-end cable. When computers are connected by a circuit switched network, they establish a direct data link over the circuit. This is used today for modem access to a data network. Modern circuit switches are based on byte multiplexing and are thus similar to packet switches, with the main difference that they perform non-statistical multiplexing.

Physical, data link and network layers are sufficient to build a packet transport system between computers. The primary goal of the transport layer is to provide the programmer with an interface to the network. Second, the transport layer uses the concept of port. A port is an address that is used locally (on one machine) and identifies the source and the destination of the packet inside one machine. The transport layer exists in two varieties: unreliable and reliable.





Wireless Network


Nowadays wireless network is very popular. We are using wireless network such a example for using mobile phone. Wireless network is an alternative to running cable around office or home. It is a network that uses radio waves or microwaves to maintain broadcast channels between computers and other networks devices. At times wireless networks are also referred as WiFi network (WLAN). In another word we don’t need to plug a cable into our computer to connect to the internet. So, wireless network is recent technology. Wireless network is used when using wireless networks permit computers, cell phones, server, radio frequencies and even printers to communicate with one another. Nowadays wireless network is rapidly growing in public to use for business and home networking. Because it is easy to setup feature and no cabling involved using. And we can connect computers anywhere in our home without the uses of wires.  Wireless technology is continues to get better, and the wireless products continues to use cost is decreases.

Wireless Operating Modes specially two operating modes there are given below:

Infrastructure mode
This type of operating mode is used to connect computers with wireless network adapter. Or it is also known as wireless clients. Existing sired network with the help of wireless access point.
Wireless access points should be set up in a method that maximizes coverage. The provided coverage is generally referred as the coverage cell. Huge areas commonly need more than one access point in arrange to have satisfactory coverage. We can also add access point to our obtainable wireless router to improve coverage.
                                                                                                                                                                                                                                                                                                                 Figure: - wireless network Infrastructure mode


Ad hoc mode:  this type of mode is used to connect wireless clients directly together without the wireless access point. If any wired networks are not setups then just we get a wireless router and attach to DSL/Cable Modem. And we can setup wireless network by adding wireless card to each of computer and form a simple wireless network. If there are switch ports available then we can connect cable directly computer.

Advantage of wireless networks:
  • We can connect to the internet from any around of location in our apartment or house of building within 30 foot radius for Bluetooth device when we are set up wireless network is properly.
  • Not only can your employees use a wireless-enabled computer in different locations around the office, they also can right of entry email, websites, and other network services via wireless access points (often called hot spots) in airports, hotels, coffee shops, and other places.
  • It is freedom to use.
  • Wireless networking is an attractive substitute to installing costly, labor-intensive network cable. And when your users can work wherever they need to be, they stay more productive
  • Wireless network include mobility and subtraction of unpleasant cables.

Disadvantage of wireless networks:

  • Wireless transmissions can pass through walls, security is an issue. You will need to secure your private wireless network, generally by password-restricting the network and by using a firewall to prevent unwelcome visitors.
  •  Wireless reception varies from area to area, even within your own apartment. It's not always guaranteed that you'll have a connection to the internet.
  • Wireless networks include the potential for radio interference due to weather, other wireless devices, or obstructions like walls.
  • When using a wireless connection with a cell phone, standard website with less functionality.






Computer Network


 

Computer networking is one of the most exciting and important technological field of our time. Computer networks are used to share the data resources and for communication in the world wide. The Internet interconnects billions of computers, providing a global communication, storage, and calculation transportation. Internet is currently being included with mobile and wireless technology, ushering in an impressive display of new applications. Computer networks and the internet connect end systems to the network center. The internet is a network of networks. The internet is very complex, both in terms of its hardware and software components, as well as in the service are provides. The public Internet is a worldwide computer network that is a network that interconnects billions of computing devices throughout the world. Increasingly, nontraditional Internet end systems such as PDAS (Personal Digital Assistants), TVs, Mobile computers, automobiles and toasters are being connected to the internet. Yet, satellite and digital line connections are also playing a role especially at the institutional, rather than individual user, level. We do all work from computer in connection with internet. Information and Communications Technologies are playing a significant role in economic, political and cultural development in the world wide. Internet is particularly well suited to facilitate and support a new and more and more popular standard in development region.  Networks in the ground of development are dedicated to the finding of new knowledge and its application for the advancement of developing nations and regions. Particularly the Internet, in the areas of health care, education, environmental protection and in other important fields can largely supply to the advancement of developing societies. Internet based communications and information processing technologies have upgraded the role of informal and information access networks the Internet is capable of running many different applications such as electronic mail, file transfer, the World Wide Web, Internet Telephony, Internet Video, MP3 music, MPEG4 video conferencing, multicasting, and interactive media services and all these radically different applications are created and installed locally by the users without any involvement of the (non-existent) controlling authority
Development networks are highly structured, have strong domination and participation is by invitation based on merit   In the case of information access networks, modern Digital Libraries provide more than access to information. The telephone network is a hierarchical entity, subject to rigid, automated internal controls. Basically the telephone network is optimized for one application: the transmission of voice (data is transmitted as voice) over real or virtual circuit paths. To introduce any new service, approval must be obtained from the telephone company which must also do the achievement of the proposed new service.

The telephone network is a hierarchical entity, subject to rigid, automated internal controls. To introduce any new service, approval must be obtained from the telephone company which must also do the implementation of the proposed new service. Internet is becoming a requirement to successful development work. Computer network is at risk to the internet and external security related theater such as: include virus, ad ware, root kits, web worms, hacker, etc. Computer network availability and security is very critical for the businesses.  Maintenance include the domain setup, dealing with the internal and external security threats, assigning IP addresses to the computes, enabling/disabling network services.

Protocols control the sending and receiving of information within the internet. TCP (the Transmission Control Protocol) and IP (the Internet Protocol) are two main protocols in the internet. The IP protocol specifies the format of the packets that are sent and received among routers and end systems. The Internet’s principal protocols are collectively known as TCP/IP. At the technical and developmental level, the internet is made possible through creation, testing, and implementation of Internet standards.
 
You need to perform to get optimize performance from computer networks:
  • Use of Systematically  Tools
  • Delete the files or document  which is Unnecessary
  • Update Device Drivers, BIOS  and Operating System
  • Not install useless Programs

Benifits And Limitation of Networks


Networking is very powerful in world wide. In modern period we use network in various work type such as when we are pickup or dialed telephone, when we are take money from ATM machine, or when we are sharing data or files in worldwide from internet, etc. That means nowadays we are not do any work without network.
There are some points about benefits from network are given below:-

  • We are sharing and transferring files or data within network are very high speed in world wide.  Thus we can save time while maintaining the truth of the file.
  • Independently many popular software programs doing licensed copies are can be costly from network. Shared program on a network allows for easier upgrading of the program on one single file server, in its place of upgrading individuality workstation.
  • We can get security from network like as sensitive files and programs on a network are protected by passwords or designated as a copy inhibit. So that we are not have to worry about illegal coping programs.
  • We can management centralized software can be loaded on one computer eliminating that need to spend time and energy installing updates and tracking files on independent computers throughout the building.
  • From network we can be shared resources like as: printers, fax machine, modems, etc.
  • We can be do electronic mail or E- mail from network. Email is personal and professional communication.
  • Network is flexible access. So we access files from computers throughout the firm.
  • Workgroup software (such as Microsoft BackOffice) allows many users to work on a document or project at the same time as.

 Some limitation about networks:-
·         Member of staff serving at table faults stop applications being presented
·          Network faults can cause loss of data and information.
·          Network fault could lead to loss of resources
·    User work (less time in more work or less work) dependent upon network. So network problem is most causes of users for working.
·         In network system open to hack.
·         Decisions have a tendency to become centralized
·         Network could become disorganized
·         Network could degrade in performance
·         Resources could be located too far from users
·         Network management can become difficult.
