What is Server Technology

 What is Server Technology


A server is a computer designed to process requests and deliver data to another computer over the internet or a local network.

Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server. For example, a Web server may run Apache HTTP Server or Microsoft IIS, which both provide access to websites over the Internet. A mail server may run a program like Exim or iMail, which provides SMTP services for sending and receiving email. A file server might use Samba or the operating system's built-in file sharing services to share files over a network.





What are they used for?


A server is a computer used in a network and which provides a service to a client. Servers usually have more processing power, memory and storage than client computers. The client is the computer that is not acting as the server, at least at that point in time, and is requesting information or a service from the server. Understanding what a server is involves an understanding of what networks are. When computers are connected in some physical (or wireless) way and sharing services or information, this is referred to as a computer network. In a computer network, there are two or more participants where at least one of them is acting as a client and one is acting as the server.

Servers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.
