Introduction

Internet and World Wide Web What is the Internet? The Internet, sometimes called simply "the Net," is a worldwide system of computer networks - a network of networks in which users at any one computer can get information from any other computer (and sometimes talk directly to users at other computers). The communication links that interconnect each host computer use a common method of transmission, known as TCP/IP, which stands for Transmission Control Protocol/Internet Protocol which is the suite of communications protocols used to connect hosts on the Internet. Communication protocols determine the format of data that all communications between devices require that the devices agree on. TCP/IP is used because TCP guarantees users that data are transmitted properly and safely without any loss of files to and fro among computers, hosts or servers and clients and IP transmit data across network routes in packets which are just pieces of messages or data. Due to its high security and speed, TCP/IP is commonly used. Each Internet computer, called a host, is independent. Its operators can choose which Internet services to use and which local services to make available to the global Internet community including files, pictures and audios. Host is a computer system that is accessed by a user working at a remote location. It is then connected to another computer systems or a TCP/IP network, including the Internet, connected by modems and telephone lines or routers. ...read more.

Below is a diagram of WAN of a company: Each host computer is identified in two ways. Firstly, each computer on the Internet has a unique assigned name, such as host1.eastern.com.bn which is referred to as its domain name. (Note: TLD is top-level domain which is the last part of the URL. There are two types of TLD. One is generic TLD and another is country code.) Secondly, each computer on the Internet also has a unique numerical address, called a TCP/IP address. This is a group of four numbers joined by dots. For example, the computer known as host1.eastern.com.bn could have a TCP/IP address of 202.72.78.5 A server is a computer or device on a network that manages network resources. It also provides resources for other computer to use as mention above. No one controls Internet and no one can claim that Internet belongs to whom even though governing bodies are responsible for issuing IP addresses and domain names depending on the type and the location of the organisations. This is to set the standards in the internet that there is no confusion. For example, a school is given a domain name of www.jis.edu.bn and another school has www.rbis.biz.uk. World Wide Web (WWW) is an Internet service that links documents locally and remotely. It also contains videos, sounds, graphics and Hyper Text links. ...read more.

A file transfer protocol can handle all types of files including binary files and ASCII text files. Another type of communication protocol is Hyper Text Transfer/Transport Protocol (HTTP). It guides the Web servers and browsers how to transmit and format the data and response to certain actions like clicking on the hyperlink to the another document causes the HTTP to ask the web servers to load the document wanted and browsers to translate the HTML format into English format which users can understand.
