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.
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.
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.
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.
