The Internet?

What is the Internet?

The Internet was first invented for only military and government uses. But now, it is found in every house across the world. The Internet is a short form for an interconnected network. It has become a vital part of our lives, helping us connect with people worldwide. The Internet is made of a large number of independently operated networks.

 

  

A server is a particular computer that is connected directly to the Internet.. Every server has a unique protocol address or an IP address. IP addresses are essential for computers to find each other.

 

A short note of the history of the Internet will help you understand when, where, and how the Internet was developed.

 History of the Internet

The Internet was developed by Bob Kahn and Vint Cerf in the 1970s.


 It was the result of another research experiment which was called ARPANET, which stands for Advanced Research Projects Agency Network. 

This was initially supposed to be a communications system for the Defense Team of the United States of America - a network that would also survive a nuclear attack.

 

 It eventually became a successful nationwide experimental packet network  which is called WWW.It is believed that on 6 August 1991, when the World Wide Web opened to the public.

 

How Does the Internet Work?

 

 Computers that we use every day are called clients because they are indirectly connected to the Internet through an internet service provider.

 

When you open a webpage on your computer, you connect to the webpage, and then you can access it.

 

 Computers break the information into smaller pieces called packets, which are reassembled in their original order. If we put the right address on a packet and send it to any computer which is connected as part of the internet so that it would get to its destination. Without confusion even with unique addresses transfer of messages by setup a router , it is called as Packet Routing Network, and hence is required to set up.

 

 










The below are the steps for how the message are transferred. This might give a basic idea of how the internet works. 

 1.     First, Computer1 sends a message by IP address to Computer2

2.     The message sent by Computer1 is broken into small pieces- packets.

3.     These small pieces- packets are transferred concerning Transfer Protocol so that the quality is maintained.

4.     Finally, these small pieces- packets reach Computer2 and are reassembled at their IP address.

 

Father of the Internet: 

Tim Berners-Lee was the man, who led the development of the World Wide Web, the defining of HTTP (HyperText Transfer Protocol), HTML (hypertext markup language) used to create web pages, and URLs (Universal Resource Locators). The development of WWW, HTTP, HTML and URLs took place between 1989 and 1991.

 

 

Tim Berners-Lee was born in London and he graduated in Physics from Oxford University in 1976. Currently, Tim Berners-Lee is the Director of the World Wide Web Consortium, the group that sets technical standards for the web.

  

Vinton Cerf is also named as an internet daddy other than Tim Berners-Lee. After being out for 10 years from high school, he began co-designing and co-developing the protocols and structure of what became the internet.

 History of HTML

In 1945, Vannevar Bush first introduced the basics of hypertext. In 1990, Tim Berners-Lee invented the World Wide Web, HTML (hypertext markup language), HTTP (HyperText Transfer Protocol) and URLs (Universal Resource Locators.

 

Evolution of the Internet

Although the Internet was developed much earlier, it only became popular in households in the 1990s.

Today, 440 million computers can be connected directly, making life easier for people across the globe. Sharing information and knowledge has become extremely easy for those that have access to the Internet. The country with the highest number of internet users is China, with 1.4 billion users, followed by India with 1.3 billion and the United States of America with a little over 0.3 billion users.

 

The Two Main Types of Computer Networks

There are different computer network types, depending on how large they are and how much geographical area they cover. The most common types are Local Area Network (LAN) and Wireless Local Area Network (WAN).

 

Local Area Network:

This is a group of devices such as computers, servers, switches, and printers that are located in the same building. These are near each other. The most common use of LAN is in houses or offices.

 

A common type of LAN is an Ethernet LAN, where two or more computers are connected to the Internet through switches.

 

Wireless Local Area Network:

This is a local area network that uses wireless communication instead of wired communication. In WAN, two computers use wireless communication to form a local area network. A wifi router is very common in this case. There are no cables involved in this case.

 

Advantages of Internet

The internet has become a popular name since the introduction of its easy installation and setup. The following are the advantages of the internet.

·         It is a great medium of sharing 

  • It  has increased connectivity.

·         With the internet, banking has now become easier. 

·         E-commerce websites are one of the great advantages of the internet. One can buy groceries, clothes, household items, and much more with the internet.

·         The Internet is also a great source of entertainment. One can watch videos and movies, listen to music, and play games, without any hassle.

·         Social media platforms like Facebook, Instagram, and Twitter have brought the world closer.

·         The education system has also transformed. With the internet, any student across the world can attend online classes.
