Internet is a network of networks in which users at any one computer can get information from any other computer if they have permission. Internet is also called “NET”. In India internet has started in 1980’s. Dial up connection, Broadband, Wireless, Internet through power lines etc are the most common ways through which we can access the net. For a dial-up internet connection we need a computer, a dial up modem and a phone line. In this kind of a connection we generally dial a number for the internet connection. Broadband connection is not a dial up connection. Here we are not required to dial a number for the internet connection. For this kind of a connection we need an ADSL modem, a phone line, a computer and some computer settings provided by the internet service provider. This connection is comparatively fast as compared to the dial up connection. Wireless internet connection is a connection which is available without wires. For a wireless connection we need a router and some computer settings. Internet is also available through the electricity cables. In India internet service is provided by MTNL, VSNL, TATA, RELIANCE, AIRTEL, Sify, Bharti Infotel Ltd etc. Through internet we can communicate with our friends, relatives, employers, employees etc. Internet can be used as a tool for earning money and for online marketing. Through internet we can gather any kind of information. We can use internet for education, for entertainment, for online shopping, for booking movie tickets, for booking airline tickets, trips etc. On the contrary, internet has security, virus and spamming threats. It has made one addicted and mechanical too. In a nutshell, internet is a necessity. It is a part of our life and cannot be ignored. Without internet we will be badly affected. Without internet we won’t be able communicate instantly, we won’t be able to carry our research projects, we won’t be able to shop, play games and we won’t be able to know that what is going around while traveling.
