Hi
I am newbie in this web hosting field. Can any one tell me what is Hosting server and how to set my web page on hosting sever?

A server is basically hardware and software and protocol.

Server hardware is so similar to your old PC hardware.All server have:

Very fast processor.
A large amount of RAM.
A vast amount of Disk Space.
Connection to a T1 line (access to the outside world).

Software. (Operating system):-There different operating systems on the market. Servers use an interface for you to access and configure them, a control panel. Some control panels are more complicated then others. Depending how technical you are, this is a point of concern when picking a server host.

FTP (file transfer protocol) is used to upload the web page.

To get your page on the server you need to FTP (file transfer protocol). FTP is a client (you) server application. If you created your page on your desk top, obviously to share it you would need to get it on your server. It’s also used to transfer files between your own pc to someone else’s computer.
