Internet is a global network connecting millions of
computers.
More than 100 countries are linked into exchanges of
data, news and opinions.
Unlike online services, which are centrally controlled, the
internet is decentralized by design.
The internet is a global system of interconnected computer
networks that use the standard Internet Protocol Suite to
serve billions of users worldwide.It is a network of networks that consists of million of
private, public, academic, business and government
networks of local to global scope, that are linked by a broad
array of electronic, wireless and optical networkingtechnologies.
The internet carries a vast range of information resources
and services , such as the interlinked hypertext documents of
the World Wide Web (WWW) and the infrastructure to
support electronic mail.

Emails are very powerful tools of communication in
an era where the need for instant communication
takes precedence over almost everything. It has become an accepted, even expected form of
communication for businesses, industries, offices,
government agencies, etc.
The convenience, speed and reach of the emailcannot be undermined and this is what works best in
its favor.
Most of us think of emails as informal
communications, but people are relying more and
more on emails as the only form of communication
and it is quickly replacing the regular snail mail in
every sphere.

oAn intranet is a computer network that uses
Internet Protocol technology to securely share any
part of an organization's information or network
operating systems within that organization.oThe term is used in contrast to internet, a network
between organizations, and instead refers to a
network within an organization.
oSometimes the term refers only to theorganization's internal website, but may be a more
extensive part of the organization's information
technology infrastructure.
oIntranet has also contrasted with extranets. While
intranets are generally restricted to employees of the
organization, extranets may also be accessed by
customers, suppliers, or other approved parties.

An extranet is a computer network that allows controlled
access from the outside, for specific business or educational
purposes.
An extranet can be viewed as an extension of acompany's intranet that is extended to users outside the
company, usually partners, vendors, and suppliers.
It has also been described as a "state of mind" in which the
Internet is perceived as a way to do business with a selectedset of other companies (business-to-business, B2B), in
isolation from all other Internet users.
In contrast, business-to-consumer (B2C) models involve
known servers of one or more companies, communicatingwith previously unknown consumer users.
An extranet is like a DMZ in that it provides access to
needed services for channel partners, without granting
access to an organization's entire network.
