History and Evolution of the Internet

Internet: Description, History & Uses | General Knowledge for Young Learners - Class 1The Internet completely revolutionised communication and technology across the Globe. Initially, computerised devices were only used for large industries but later its usage increased massively.
It is also mandatory for people to know that it is not possible for a single person to develop something as broad and wide as the Internet all by himself/herself. It was a combined effort of multiple researchers and programmers that the Internet was discovered. 
Given below are a few important points which played an extremely important role in the development of the Internet and making it one of the most widely used resources across the world. 

  • The first development was the introduction of host-to-host network interactions. This was first observed in ARPANET in 1969. It was developed by Advanced Research Projects Agency (APRA) of the Department of Defence, U.S. It was one of the first general usage of computer networks.
  • Next step was commercialising the usage and making the transistors and transmitters fit in smaller devices for convenient Internet usage for the general public. This was introduced in the 1970s
  • Moving forward, satellites and wireless communication was the main target. Defence Advanced Research Projects Agency (formerly ARPA), supported satellite-based radio packets for mobile usage of networks
  • The next was the development of Transmission Control Protocol (TCP). This enabled different machines and networks across the world to assemble data packets. It was in the 1980s that the TCP/IP approach was adapted by researchers and technologists, following the footsteps of the U.S. Department of Defence
  • With the introduction of personal computers, the demand for commercial Internet usage increased. This was the time when Ethernet and other Local Area Networks cam in the foreground
  • In 1993, the web browser was introduced, which followed the point-and-click approach and is now a widely used operation for Internet users
  • The late 1990s was the time when thousands of Internet Service Providers has taken up the market and most of them were from the U.S.
  • And then the 21st century brought in an amalgamation of technology and wireless Internet accessibility for its users. Wherein, wireless broadband services came in as a boon for Internet users

Amid all these developments which were made, a lot of successes and failures came in but today, the Internet is one such commodity which has made lives easier and brought in a wider pace for development across the globe.
