INTRODUCTION TO INTERNET AND WORLD WIDE WEB

1.1    THE INTERNET
The earnest need for very effective and efficient ways of handling modern communication cannot be over-emphasized, as communication remains to be the major sustenance of world Existence.  invariably, without good communication the world would be difficult place to live in. Networking refers to the connection of two or more computers to communicate with one another.  That is when millions of computers in different location around the world are connected together which allow users to send and received message to one another brought about the internet.

The internet simply stands for INTERnational NETwork and can be defined as the global information system that provides, uses or makes accessible, either publicly or privately high level services layered on the communications and related infrastructure.   It can also be described as a worldwide connection of computer network, cooperating with each other to exchange data using a common software standard. It is a global network connecting millions of computers around the world together to share the same resources.  It is sometimes called "the Net" and is a worldwide system of computer networks that allows users to send and receive information from one other.

The Internet allows access to whole resources of data and information stored at different sites (called hosts) and locations all around the world.  When the computer is connected to the internet, it can communicate (i.e it can send or receive information) with any other computers on the internet.  But this doesn't give it access to everything that is stored on that computer except those kind of information made accessible through the internet and restrict access to other private information so that only authorized people can see it.
The communication links which interconnect each host computer use a common method or transmission protocol called TCP/IP (Transmission Control Protocol/Internet Protocol).  The Great thing about the internet's design is that it is open to all types of computer (PC, Laptop, Palmtop, Supercomputer, Mainframe Computer, etc)

Unlike Online services, which are centrally controlled, the Internet is decentralized by design.  Each internet computer called a host, is independent.  Its operator can choose which local services to use and which local services to make available to the global internet community.  It offers very practical use in several human endeavors and it is an essential medium if communication and interaction with the people worldwide
