What is the internet?
The Internet is a global system of interconnected computer networks that use the
standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a
network of networks that consists of millions 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 networking technologies. The Internet carries an
extensive range of information resources and services, such as the inter-linked
hypertext documents of the World Wide Web (WWW) and the infrastructure to
support email.
Most traditional communications media including telephone, music, film, and
television are reshaped or redefined by the Internet, giving birth to new services such
as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV).
Newspaper, book and other print publishing are adapting to Web site technology, or
are reshaped into blogging and web feeds. The Internet has enabled or accelerated
new forms of human interactions through instant messaging, Internet forums, and
social networking. Online shopping has boomed both for major retail outlets and
small artisans and traders. Business-to-business and financial services on the
Internet affect supply chains across entire industries.
The origins of the Internet reach back to research of the 1960s, commissioned by the
United States government in collaboration with private commercial interests to build
robust, fault-tolerant, and distributed computer networks. The funding of a new U.S.
backbone by the National Science Foundation in the 1980s, as well as private funding
for other commercial backbones, led to worldwide participation in the development of
new networking technologies, and the merger of many networks. The
commercialization of what was by the 1990s an international network resulted in its
popularization and incorporation into virtually every aspect of modern human life. As
of 2011, more than 2.1 billion people — nearly a third of Earth's population — use the
services of the Internet.
The largest network of the networks is called the internet.
Brief history of the internet
ARPA – Advanced Research Project Agency.
1969 January 2 – started an experimental Computer Network.
Concept – No Server, but equal importance/participation to every computer in the
Network.
Even if, one or two node destroyed that will not affect the Network.

Electronic Mail
Electronic mail, commonly known as email or e-mail, is a method of exchanging
digital messages from an author to one or more recipients. Modern email operates
across the Internet or other computer networks. Some early email systems required
that the author and the recipient both be online at the same time, in common with
instant messaging. Today's email systems are based on a store-and-forward model.
Email servers accept, forward, deliver and store messages. Neither the users nor
their computers are required to be online simultaneously; they need connect only
briefly, typically to an email server, for as long as it takes to send or receive
messages.
An email message consists of three components, the message envelope, the
message header, and the message body. The message header contains control
information, including, minimally, an originator's email address and one or more
recipient addresses. Usually descriptive information is also added, such as a subject
header field and a message submission date/time stamp.Distributes e-mail messages
and attached files to one or more electronic mailboxes. Message can consist of
attachment, graphic or video/audio clips.
Eg :- e-mail address thomas@mes.edu.in

File Transfer Protocole (FTP)
File Transfer Protocol (FTP) is a standard network protocol used to transfer files from
one host to another host over a TCP-based network, such as the Internet. FTP is built
on a client-server architecture and uses separate control and data connections
between the client and the server. FTP users may authenticate themselves using a
clear-text sign-in protocol but can connect anonymously if the server is configured to
allow it.
The first FTP client applications were interactive command-line tools, implementing
standard commands and syntax. Graphical user interface clients have since been
developed for many of the popular desktop operating systems in use today.
