Hello, everyone.
So in this video we are going to learn about what is
internet.
What is intranet what is Extranet and
we are going to see the breakdown of all of
them?
So what is internet?
Internet is a globally connected network of computers
that enables people to share
information and communicate with each other.
And simple language all of us use internet into
a day-to-day life.
We use a lot of social media Instagram Facebook
Snapchat.
What we are doing is transferring information.
On all these platforms and communicating with our
friends and family.
This is how basically internet works.
So what is Intranet?
Intranet on the other hand is a local or
restricted Network for people to
store organize and share information within
an organization.
for instance if a person is working in
a company X
Then he is able to share the data or communicate between
the company premises only into
the local network only this is
referred as Intranet.
So what is Extranet?
extra net for instance
a web portal there is accessible by an
organization and it's external vendors Partners
customers or any types of users that
require access to some restricted information from
outside.
So basically in simple terms extra net
is the type of network, which is
restricted intranet wherein
people from outside can access
the restricted information.
of any organization X
So let's break it down.
Inter means complete internet intra
means inside which is intranet and
extra which is extra net means
outside as you can see into the
figure on the right hand side.
Intranet is in the center, which is
the internal network of any company or
organization.
if
that particular network is to be accessed from
outside.
Through which anyone can access the restricted information
by authorizing himself is Extranet.
And at the last is the internet which comprises of
the intranet as well as the Extranet.
So I hope you guys understood why.
We call it intranet Extranet and
internet.
On the bigger hand and the bigger picture internet is
the biggest and intranet and
Extranet are the subset of it.
Thank you.
