What is the Internet? While it may seem like a simple question, defining the Internet isn’t easy.

Because unlike any other technology, the Internet can be whatever we make it. We can shape it.

We can mold it. But most importantly, we can use it to connect people, communities, and countries around the world.

Hows Does it Work?

The Internet works because open standards allow every network to connect to every other network.

This is what makes it possible for anyone to create content, offer services, and sell products without requiring permission from a central authority.

It levels the playing field for everyone and it’s the reason why we have a rich diversity of applications and services that many of us enjoy today.

Who is in charge of the Internet?

No one is, but everyone is.

Unlike the telephone network, which for years in most countries, was run by a single company, the global Internet consists of tens of thousands of interconnected networks run by service providers, individual companies, universities, governments, and others.

How do these networks talk to one another?

The secret of the Net is a network protocol called TCP/IP–that is, a kind of coding system that lets computers electronically describe and interpret (send and receive) data over the network.

The term actually refers to two separate parts: the transmission control protocol (TCP) and the Internet protocol (IP). Together they form the language of the Internet.

Every computer that hooks to the Internet understands these two protocols and uses them to send and receive data from the next computer along the network.

Uses of Internet:

The uses of internet are discussed below:

§  With Internet, we can connect to people in just a moment.

§  We can mail anywhere in the world in a moment with the fastest mailing service of the world called “email”.

Features of Internet:

The features of internet are discussed below:

§  Commuters have the capabilities to communicate with each other. If connectivity is given, information can be exchanged between the computers.

§  A group of computers in a net system are connected with the help of wires, or cables or wireless.

§  The communication function between the computers facilitate to access information residing in one computer from another computer.

§  It is the software and hardware which constitute the network.

§  A network may be a simple network of two computers, an office network of more than two computers, network of networks, larger network, and network for network of networks around the world.

Components of Internet:

The various components of internet is discussed below:

§  World Wide Web: The World Wide Web (abbreviated as W3 or WWW) as a system to access thousands of servers that supports different Internet protocols on a single Interface. To access various services of Internet, different protocols are required at different periods of time on the web. These services include E-mail, FTP, Telnet and Usenet news. WWW has its own protocol also called HTTP (Hyper Text Transfer Protocol).

§  E-mail: E-mail is the ability to send and receive messages with people throughout the world sitting at different locations. It has been one of the greatest strengths of the Internet. Electronic mail allows computer users locally and worldwide to exchange messages. Messages sent through e-mail arrive within few seconds, the senders and receivers must have their e-mail addresses.

§  Telnet: Telnet stands for Terminal Network. It enables an internet user to log on to a remote computer or network throughout the world. And use them if they were sitting at that terminal locally. Telnet is a member of TCP/IP family of internet protocols and allows communications with any computer linked over the internet.

§  FTP: The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet. FTP is most commonly used to download a file from a server using the Internet or to upload a file to a server (e.g. uploading a Web page file to a server).

Advantages of Internet:

The Internet is so far one of the greatest inventions of all time. The Internet has made it possible for us to do lots of things. The Internet has proven to be very useful and has come with lots of advantages. Here are some advantages:
