       What is server ??       

                     

Definition - A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet.

   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.

      Different types of Servers.      

Web Server

               At its core, a Web server serves static content to a Web browser by loading a file from a disk and serving it across the network to a user's Web browser. This entire exchange is mediated by the browser and server talking to each other using HTTP.


Mail Server

              Almost as ubiquitous and crucial as Web servers, mail servers move and store mail over corporate networks (via LANs and WANs) and across the Internet.


Server Platforms

              A term often used synonymously with operating system, a platform is the underlying hardware or software for a system and is thus the engine that drives the server.


Application Server

               Sometimes referred to as a type of middleware, application servers occupy a large chunk of computing territory between database servers and the end user, and they often connect the two.


Real-Time Communication Server

              Real-time communication servers, formerly known as chat servers or IRC Servers, and still sometimes referred to as instant messaging (IM) servers, enable large numbers users to exchange information near instantaneously.


FTP Server

                One of the oldest of the Internet services, File Transfer Protocol makes it possible to move one or more files securely between computers while providing file security and organization as well as transfer control.


Collaboration Server

                  In many ways, collaboration software, once called 'groupware,' demonstrates the original power of the Web. Collaboration software designed to enable users to collaborate, regardless of location, via the Internet or a corporate intranet and to work together in a virtual atmosphere.


List Server

               List servers offer a way to better manage mailing lists, whether they be interactive discussions open to the public or one-way lists that deliver announcements, newsletters or advertising.


Telnet Server

              A Telnet server enables users to log on to a host computer and perform tasks as if they're working on the remote computer itself.


Open Source Server

               From your underlying open source server operating system to the server software that help you get your job done, open source software is a critical part of many IT infrastructures.


Virtual Server

                In 2009, the number of virtual servers deployed exceeded the number of physical servers. Today, server virtualization has become near ubiquitous in the data center.

More Info:



  • While server software is specific to the type of server, the hardware is not as important. In fact, a regular desktop computers can be turned into a server by adding the appropriate software. For example, a computer connected to a home network can be designated as a file server, print server, or both.



  • While any computer can be configured as a server, most large businesses use rack-mountable hardware designed specifically for server functionality. These systems, often 1U in size, take up minimal space and often have useful features such as LED status lights and hot-swappable hard drive bays. Multiple rack-mountable servers can be placed in a single rack and often share the same monitor and input devices. Most servers are accessed remotely using remote access software, so input devices are often not even necessary.

  • While servers can run on different types of computers, it is important that the hardware is sufficient to support the demands of the server. For instance, a web server that runs lots of web scripts in real-time should have a fast processor and enough RAM to handle the "load" without slowing down. A file server should have one or more fast hard drives or SSDs that can read and write data quickly. Regardless of the type of server, a fast network connection is critical, since all data flows through that connection.
