Effect of Internet Development

The Internet has made a new revolution in the world of computer and communications world that have never previously suspected. Some findings telegraph, telephone, radio, and computers is a series of scientific work that led to the creation of the Internet a more integrated and more capable than those tools. Internet has the capability of broadcasting to the world, has a mechanism for information dissemination, and as a medium for collaboration and interaction between individuals with the computer without being limited by geography.
The Internet is a most successful example of business investment that can never stop and commitment to research following the development of information technology infrastructure. Starting with a study packet switching (packet switching), government, industry and the civitas academica have collaborated effort to change and create this exciting new technology.
Development History of intenet can be divided into four aspects:

   1. The existence of aspects of technological evolution that started from the research packet switching (packet switching), ARPANET (the following equipment technology) which was then carried out further research to develop insights into the data communications infrastructure that includes multiple dimensions such as scale, performannce / reliability, and high-level kefungsian.
   2. The existence of aspects of the implementation and management of a global infrastructure and complex.
   3. The existence of the social aspects that result in a large community consisting of the Internauts who cooperate to create and develop this technology continues.
   4. The existence of commercial aspects resulting in an extreme but effective changes from a study that resulted in the formation of a large infrastructure and useful information. Internet now is a global information infrastructure (widespread information infrastructure), which was originally called "the National (or Global or Galactic) Information Infrastructure" in the United States. Its history is very complex and covers many aspects such as technological, organizational, and community. And its effect not only on the field of computer communication techniques, but also affected the social problems as of now we do is we use many tools on line to achieve an electronic business (electronic commerce), ownership information and interact with the community.

Internet Development

Information Technology and Telecommunications (Information and Communication Technology / ICT) is the backbone of Web 2.0 applications. Information and Communication Technology Development phenomenal and the early emergence of web applications is the Internet. Internet that originated from research for defense and security and education developed into a business support device that is very influential. In connection with this Web 2.0 applications, there are some important events in the history of the internet. Starting in 1957, through the Advanced Research Projects Agency (ARPA), the United States determined to develop an integrated communications network that connects between the scientific community and military purposes. This is motivated by the cold war between the United States with the Soviet Union (in 1957 the Soviets launched sputnik).
Internet's first major development was the most important invention of packet switching ARPA in 1960. Packet switching is the sending of messages that can be broken down into smaller packages, each package can be through a variety of alternative paths if one of the main damage path to achieve its intended purpose. Packet switching also allows the network can be used simultaneously to do a lot of connections, unlike phone lines which require a special lane to make a connection. So when the ARPANET into the national computer network in the United States in 1969, used a whole packet switching as a communication method that is used to replace circuit switching in a public telephone.
The development of the Internet both recorded in the history of the Internet is developing a network protocol layer which is famous for now is the most widely used TCP / IP (Transmission Control Protocol / Internet Protocol). Protocol is a set of rules to relate antarjaringan. This protocol was developed by Robert Kahn and Vinton Cerf in 1974. With a standard protocol and widely agreed upon, then the local network spread in different places can be interconnected to form a network giants even today span the globe. Network using Internet protocol is often referred to as the Internet network.
ARPANET networks become even greater since then and began to be managed by private parties in 1984, it incorporated more and more universities and commercial companies began to enter. Protocol TCP / IP into an agreed common protocol so that it can communicate with each other on this Internet network.
The third major development was the establishment applications Internet World Wide Web in 1990 by Tim Berners-Lee. Application World Wide Web (WWW) has become the content that awaited all Internet users. WWW make all users can share a variety of applications and content, as well as linking together the scattered material on the internet. Since then the growth of Internet users skyrocketed.

Understanding the Internet

The Internet is a global network of computers of the world, big and very wide at all in which each computer are connected to each other from country to country around the world and contains various information, ranging from text, images, audio, video, and more.
Internet itself comes from the word Interconnection Networking, which means the relationship of many computer networks with various types and species, using a type of communication such as telephone, salelit, and others.

In a set of integration and computer network communication protocol that uses TCP / IP. TCP (Transmission Control Protocol) duty to ensure that all links are working properly, while the IP (Internet Protocol) which transmits data from one computer to another. TPC / IP in general serves to choose the best route of transmission of data, choosing an alternative route if a route can not be in use, manage and transmit packets of data transmission.

To be able to participate using the Internet facility, you must subscribe to an ISP (Internet Service Provider) that exist and serve your area. ISPs are usually called Internet service providers. You can use the facilities from Telkom as Telkomnet Instant, speedy and also other ISP services such as first media, netzip and so forth.

The Internet offers many benefits, one can provide the benefits of good and bad. Good when used for learning information and bad when used for things that pornography, violence information, and others negative.

Internet allows computer users around the world to communicate and share information by sending each other emails, connecting one computer to another computer, send and receive files in the form of text, audio, video, discuss certain topics on the newsgroups, social networking websites and others.

Internet history

History of the Internet and Internet Development

History of the intenet began in 1969 when the Department of Defense, U.S. Defense Advanced Research Projects Agency (DARPA) decided to conduct research on how to connect a number of computers so as to form an organic network.

This research program known as the ARPANET. In 1970, already more than 10 computers are successfully connected to each other so that they can communicate with each other and form a network.
In 1972, Roy Tomlinson managed to complete the e-mail program that he created a year ago for the ARPANET. E-mail program is so simple it immediately became popular. In the same year, the icon @ also introduced as an important symbol that shows the "at" or "on". In 1973, ARPANET computer network were developed outside the United States.

Computer University College in London is the first computer that is outside the United States who are members of ARPAnet network. In the same year, two computer experts that Vinton Cerf and Bob Kahn presented a bigger idea, which became the forerunners of the Internet thinking. This idea was presented for the first time at the University of Sussex.

The next historic day is March 26, 1976, when the Queen of England managed to send an e-mail from the Royal Signals and Radar Establishment at Malvern. A year later, already more than 100 computers on ARPANET joined to form a network or network. In 1979, Tom Truscott, Jim Ellis and Steve Bellovin, creating the first-named newsgroups USENET. In 1981 France Telecom creates a buzz by launching the first television telephone, where people can call each other while associated with the video link.

Because the computers that form a network of daily increasing, it needed a formal protocol that is recognized by all networks. In 1982 established Transmission Control Protocol or TCP and Internet Protocol or IP as we know it all. Meanwhile in Europe appear counter computer network known as Eunet, which provides computer network services in these countries the Netherlands, Britain, Denmark and Sweden. Eunet network providing e-mail and USENET newsgroups.

To homogenize the address on existing computer networks, then in 1984 the domain name system was introduced, which now we are familiar with DNS or Domain Name System. Computers that are connected with the existing network has more than 1000 computers more. In 1987 the number of computers that are connected to the network soared 10-fold more manjadi 10,000.

In 1988, Jarko Oikarinen of Finland discovered and at once introduced the IRC or Internet Relay Chat. A year later, the number of interconnected computers soared 10-fold return in a year. No fewer than 100,000 computers are now forming a network. Year 1990 is the year's most historic, when Tim Berners Lee to find a program editor and browser that can roam from one computer to another computer, which form a network. The program is called www, or worl Wide Web.

In 1992, computers that are connected to each other form the network has exceeded a million computers, and in the same year the term surfing the internet. In 1994, the website has grown to 3000 pages address, and for the first time in a virtual-shopping or e-retail surfaced on the internet. The world changed. In the same year Yahoo! established, which is also well-born Netscape Navigator 1.0.
