2. HISTORY
OF

• The foundation of Internet was laid by the
department of defense, USA in 1969. This
network was named as ARPANET. This was the
first step towards the creation of the Internet.
Internet, however , came to the existence in
proper way in the 1990’s.
• The Internet’s growth has become explosive and
it seems impossible to escape the bombardment
of www.com which is seen constantly on
television , magazines and heard on radio.
Because the internet has become such a large
part of our lives, a good understanding is required
to use this new tool most effectively.

a result of the TCP/IP architecture.
• Similarly, BITNET ( Because it’s
Time Network ) connected IBM
mainframes around the educational
community and the world to provide
mail service beginning in 1981 .

4. Communication and
working of internet
• Internet refers to a collection of
infinite number of computers that
are spread all across the globe. It
is a global network of similar or
dissimilar networks across the
world, with a purpose of sharing
resources and to communicate with
each other. It is also called as
network of networks.

5. Protocols
• It is a set of rules that govern
communication between
computers. Protocols specify
secure interactions between
the communicating computer
devices. A network protocol
defines rules and convictions of
communication between
network devices.

6. Address of your computer
over the Internet
• The Internet is a global network of
computers each computer
connected to the Internet, must have
a unique address. This address is
known as an IP address. If you
connect to the internet through an
Internet Service Provider (ISP), you
are usually assigned a temporary IP
address for the duration of your dialin session.

7. Some Internet NetWorking Devices
Modem and its working
Modem takes it’s name from the words
Modulator-Demodulator which is actually a
device, which is used for conversion of
data signals. It enables a computer to
transmit data over the network.
Computer information is stored digitally
whereas information transmitted over
telephone lines in the form of analog
waves.

8. Who Manages The
Internet
• World Wide Web consortium (W3C)
The World Wide Web
Consortium (w3c) is the main international

• Internet Engineering Task Force (IETF)
The IETF ’s mission is “ to make the
Internet work better”. It makes the
Internet work better from an engineering
point of view.

9. Applications Of Internet
• E-MAIL : By using internet we can
communicate in a fraction of seconds with
