What is WAMPServer?

WAMP is a form of mini-server that can run on almost any Windows Operating System. WAMP includes Apache 2, PHP 5 (SMTP ports are disabled), and MySQL (phpMyAdmin and SQLitemanager are installed to manage your databases) preinstalled.

An icon on the taskbar tray displays the status of WAMP, letting you know if; a) WAMP is running but no services are opened (the icon will appear red), b) WAMP is running and one service is opened (the icon will appear yellow) or c) WAMP is running with all services opened (the icon will appear white). Apache and MySQL are considered to be services (they can be disabled by left-clicking on the taskbar icon, guiding your cursor over the service you wish to disable and selecting "Stop Service").

The files/web pages that are hosted on your WAMP server can be accessed by typing http://localhost/ or http://127.0.0.1/ in the address bar of your web browser. WAMP must be running in order to access either of the above addresses.

If you would like to share your files/web pages with others, click on the icon located on your taskbar tray and select "Put Online." You must have access to the Internet in order to continue.
You can download WAMPServer from WampServer.com.

What is Network?

A network or communication network is a system of interconnected communication devices that can communicate with one another and share information. Therefore computer network can be defined as:
A system in which more than one computers or large number of computers are interconnected together, communicate freely with one another and share information is called computer network.

A network can be internal to an organization or span the world by connecting itself to the internet. In computer network, network operating system is used that controls and co-ordinates the activities of computers that are connected to the network. The example of these operating systems are: windows NT, UNIX, and Novell etc.

Types of Network

Networks are of three types. These are:

* Local Area Network (LAN)
* Wide Area Network (WAN)
* Metropolitan Area Network (MAN)

Local Area Network

A local area network is a network system in which computers are interconnected in a limited geographical area, such as network of computers in college computer laboratory or network of computers in office building etc.

Wide Area Network

A wide area network is a network system that covers a large geographical area such as different cities of country or different countries of the world. In WAN telephone lines, satellites, microwave, fiber optic etc. are used as transmission media.

Metropolitan Area Network

A Metropolitan area Network is a network system that covers area of a single city. Usually, MAN connects more than one LANS in a city or town and covers a smaller geographical area than a WAN. The cable television, telephone companies or local corporations use MAN.
