DO YOU KNOW? That Timothy Berners-Lee, a British computer scientist, developed the World Wide Web during the 1980s. With him and his group (CERN), WWW has been enabled to make computers interact and communicate to each other. This scientist has contributed in the advancement of the computer today, but he started from somewhere as we all know. From the name WEB, derived from the studying of a spider building a web, shows that it is a service of inter connected computers.

The Internet and the Web are each a series of interconnected computer networks. Personal computers or workstations are connected to a Local Area Network (LAN) either by a dial-up connection through a modem and standard phone line, or by being directly wired into the LAN. The one that is common to those that see modem as a burden, since it job is just enable the computer browse, is the standard phone lines making use of Bluetooth or via cable to connect to the internet, since it can make call and perform so many task.

Any computer can run a client or a server. In practice, however, powerful computers are usually chosen to run server software, and small personal computers (PCs) are sufficient to run client software.

PCs, however, are used by a single person to request a Web page. After a user makes a request, the user waits for the information to be displayed. Thus, the client program running on a user’s computer only needs to handle one activity at a time. A server, however, must handle simultaneous requests from many clients, possibly millions.

All the information on the web are divided into pages, each of which are assigned a short identification string that is known as a uniform resource locator (URL). A URL encodes three pieces of information: the protocol a browser should use to obtain the item, the name of a computer on which the item is located, including its domain name, and the name of the item. The domain name indicates whether the site is operated by a commercial or nonprofit business.

For example, .com is a commercial site whereas .org is a nonprofit site. Many other domain names exist, including .edu for web sites established by educational institutions.
To access the Web, a user must have a computer connected to the Internet and appropriate software, known as browser. Only the computer name is required in a URL. If the protocol is omitted, a browser assumes “http://,” and if the name of an item is omitted, the server chooses a page to send.

The difference between the Web and the Internet is similar to the difference between a trucking service and a highway system.

The Internet corresponds to a highway that allows traffic to flow between computers, and the Web corresponds to a service that uses the highway to move information from one computer to another. Confusion about the difference between the Web and the Internet has arisen because the Web has become extremely popular and currently accounts for the majority of Internet traffic.

However, other services also use the Internet to carry their traffic. For example, the Internet electronic mail service permits users to send and receive textual messages, and the file transfer service allows a user to transfer a copy of a file from one computer to another. Also, due to the complexity of operations that computer possesses, games and controllable software has been created for downloads from the internet in other to create an atmosphere of entertainment and fun.

In conclusion, computers are the “all in all” in our day to day activities, since it can send and receive files, information, and so on. At least with computer, some works has become easier in the world today.
