What is the Internet?
The Internet is a large group of computers that are linked together. There
are millions of computers that are connected to this network across 200 countries.
The users of these computers can communicate with each other by sending emails,
transferring files, instant messaging, etc. Every computer which is connected to the Internet
has an address, which is called an Internet Protocol Address (IP Address). The IP address is a series of numbers separated by dots,
for example: 123.45.67.890.
How does it work?
Computers which are connected to the Internet have different functions. Computers (users) that get information on the web are
called clients. Other computers only store files such as photos, music, emails, videos or websites. These computers are called
servers. A client can access a server to visit a website, check an email account, etc.
When two computers exchange information, they are called peers. Some examples of this are instant messaging or sending photos
to a friend directly. When two peers are interacting with each other, it is called peer-to-peer (P2P) communication. For example,
if you receive a photo from your friend, your computer is the client because you access the file and your friend’s computer acts as
a server because he or she supplies the photo.
Who invented the Internet?
In the 1960s, researchers from the Government Defense Department in the USA were looking for a way to continue working in
case some computers got or damaged because of a war or a natural disaster. They came up with a network that linked several
computers together. In 1969, their network began operating and was called the ARPANET.
Over the years, universities, large businesses, and other major organizations joined this network to exchange ideas and resources
with each other.
