What is the internet

The internet is a global network of computers. They use common "language" called TCP/IP. Every computer use an IP address.

How it works

Do you need to know how your packets of internet data are transmitted through a variety of cables, routers and host computers to their destination.

Different packets can take different routes, which makes the internet relatively resilient.

The internet data packets also carry different types of data for different applications. Common types include web pages, email messages, and large files that might be digital vidfeos, music files or computer programs.

Today, the web is often used to provide an easy-to-use interface for numerous applications, including email or file transfer.

Origins of the net

The internet traces its origins to the ARPAnet, created by the US Defence Department's Advanced Research Projects Agency in the 1960s.

Vint Cerf and Bob Kahn developed TCP/IP (Transmission Control Protocol / Internet Protocol), to connect different networks.

At the end of 1969, there were only four computers on ARPAnet, and they were all at US universities.

Global domination

Web browsers have made the internet easy enough for anyone to use.
now the internet access is becoming popular on mobile phones.

How does the web work?

The web is a system for publishing pages on the internet.

Anyone can publish a page by uploading it to a web server. Anyone can read that page by typing the address into a web browser.

You don't need to enter all the URL (Uniform Resource Locator) of a web page, because web pages can include links or hyperlinks.
