2. Intranet
• An intranet is a private network accessible only to an organization's staff.

3. Evolution
• The concept of Internet was originated in 1969 and has undergone several
technological & Infrastructural changes as discussed below:
• The origin of Internet devised from the concept of Advanced Research Project Agency
Network (ARPANET).
• ARPANET was developed by United States Department of Defense.
• Basic purpose of ARPANET was to provide communication among the various bodies
of government.
• Initially, there were only four nodes, formally called Hosts.
• In 1972, the ARPANET spread over the globe with 23 nodes located at different
countries and thus became known as Internet.
• By the time, with invention of new technologies such as TCP/IP protocols, DNS,
WWW, browsers, scripting languages etc.,Internet provided a medium to publish and
access information over the web.

5. The Difference Between an Intranet and Internet
• An intranet is designed to allow a company to share information and resources with
others in the company, for group projects and teleconferencing. This is in contrast to
the Internet, which is public access.
• There's one major distinction between an intranet and the Internet: The Internet is
an open, public space, while an intranet is designed to be a private space. An
intranet may be accessible from the Internet, but as a rule it's protected by a
password and accessible only to employees or other authorized users.

and quicker and easier communication.

tools, interactive tools, social platforms, content repositories, employees can gain help as
well as improve their working process. This increases productivity and at the same time

getting hacked are minimized. In the internet, the security of the organization’s website
and dealings are usually lowered.

eases information searching and it provides tools to make work quicker. This helps in

employees access to limitless information from the outside and organization specific
information from the inside.
