IT AND INTERNET


Internet has transformed our lives and the way we communicate, how we learn, how we
work and spend free time. In essence it has more or less changed every aspect of human society
one can think of. The significance of the Internet and Information Technology in both nosiness and
private field has grown considerably in the last few years, with exponential growth of Internet
users and services offered.
The internet is a global system of interconnected computer networks that interchange data
by packet switching using the standardized Internet Protocol Suite (TCP/IP). It is a “network of
networks” that consists of millions of private and public academic, business, and government
networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless
connections, and other technologies. The Internet carries various information resources and
services, such as electronic mail, online chat, file transfer and file sharing, online gaming, and the
inter-linked hypertext documents and other resources of the World Wide Web (WWW). The
WWW is the graphical Internet service that provides a network of interactive documents and the
software to access them. It is based on documents called pages that combine text, pictures, forms,
sound, animation and hypertext links called hyperlinks.
Internet is accessed using a browser, which is a piece of software that acts as an interface
between the user and the inner-workings of the internet specifically the WWW.
Internet is the cheapest and fastest means to get, provide and compile information
