The Internet: A Complete Explanation & Guide

Communication is one of the most popular use of the Internet. The Internet is make it easier for people to communicate with one another by using computers.

Introduction of Internet

The Internet has been in a state of continuous evolution since the late 1960s. Some simplified description of the Internet, are “a large computer network” or “network of networks “” “an instantaneous and global messaging system”. Internet is an immensely complex combination of thousands of technologies and dozens of services use by tens of millions of people around the world each day. Internet is thus, a network of networks. The Internet is a network of thousands of computer network. Every network and every computer in these network exchange information according to certain rules called protocols. These different computers and different network are united with the common thread. Of two protocol, I.e., Internet Protocol (IP) and Transmission Control Protocol (TCP).

The Origins of the Internet:

The Internet took time to emerge. It began in the late 1960s and developed across several decades:

ARPANET (1969):

Almost created by the Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense, ARPANET was the first actual forerunner of the Internet. It was created to enable information sharing amongst researchers over a computer network. The system crashed after the first two letters (“LO” of “LOGIN”) in the first message ever delivered, which was between UCLA and Stanford.

Packet Switching:

Further, packet switching was created as a new data transfer technique. Data was delivered in little units (packets) rather than in one big block, which were then sent independently and put back together when they got to their destination. This turned into a core tenet of the Internet.

TCP/IP Protocol (1983):

One significant turning point was the creation and uptake of the Transmission Control Protocol/Internet Protocol (TCP/IP) in 1983. It laid the foundation for the current Internet by enabling communication and connection between many networks.

Expansion in the 1980s and 1990s

• NSFNET and Universities NSFNET, established by the National Science Foundation in the middle of the 1980s, served as the foundation of the early Internet by linking several academic networks.
• The World Wide Web (1991): The World Wide Web was created in 1991 by British scientist Tim Berners-Lee. The Web made it possible for people to access and exchange its information through hyperlinks and browsers, in contrast to the Internet, which was already a network of networks. Nowadays, this is what most people think of when they hear the word “Internet.”
• Commercial Use: The Internet was made available for business usage during the beginning of the 1990s. As a result, the first websites, email services, and Internet service providers (ISPs) emerged.
