History and Evolution of the Internet

The 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 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 computer networks
  • Next step was commercialising the usage and making the transistors and transmitters fit in smaller devices for convenient Internet usage for 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 1980s that the TCP/IP approach was adapted by 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, web browser was introduced, which followed the point-and-click approach and is now a widely used operation for Internet users
  • 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, Internet is one such commodity which has made lives easier and brought in a wider pace for development across the globe.

Since Computer Awareness is an important topic from the Government examination point of view, candidates can get a more understandable explanation of the Internet and its various aspects by reviewing the video given below:

Ways To Connect To Internet

The different ways in which one can connect to the Internet are discussed below in brief:

  • Dial-Up – In such connections, users are required to link their phone line to a computer to access the Internet. Under this connection, the user cannot make or receive phone calls through tier home phone service
  • Broadband – Provided either through cable or phone companies, Broadband is a high-speed internet connection which is widely used today
  • Wireless Connection – Wi-fi and Mobile service providers fall under this category. Internet connectivity is made via radio waves and the Internet can be connected anywhere, irrespective of the location. Given below are a few examples of wireless connection:
    • Wi-fi – Wireless Fidelity or wi-fi allows high-speed internet connectivity without the use of wires
    • Mobile Phones – All smartphones are now equipped with an option for Internet connectivity which can be availed using Internet vouchers and packs. No external connection or wire is required for these
    • Satellite – Where broadband connections are unavailable, satellites are used for wireless Internet connectivity
    • Integrated Services Digital Network – ISDN allows users to sent audio or video data using telephone lines

Aspirants for Government exams can check the links given below and practise more and more questions from the different sections and topics which are included in the competitive exam syllabus:

Internet Connection Protocols

Protocols are a set of rules that help in governing the way in which any particular body or technology works.

Internet Connection Protocols can be divided into three major types:

  • TCP/IP Network Model – Transmission Control Protocol (TCP) and Internet Protocol (IP) are the most widely used protocols for connecting networks. It divides any message into a series of packets which are sent from source to destination
  • File Transfer Protocol – Program files, multimedia files, text files, documents, etc. can be transferred from one device to another, using FTP
  • Hypertext Transfer Protocol – Used for transferring a hypertext from one device to two or more devices. HTML tags are used for creating links and these links may be in the form of text or images

Internet forms an integral part of computer usage today and is an important topic to be well prepared for govt exams. Given below are links to other such important subjects which are a part of the syllabus:
