A client is a Computer System that accesses a (remote) service on another Computer by some kind of Network . The term was first applied to Device s that were not capable of running their own stand-alone Program s, but could interact with remote computers via a network. These Dumb Terminal s were clients of the Time-sharing Mainframe computer. The Client-server model is still used today on the Internet , where a User may connect to a service operating on a remote system through the Internet Protocol Suite . Web Browser s are clients that connect to Web Server s and retrieve Web Page s for display. Most people use E-mail Client s to retrieve their E-mail from their Internet Service Provider 's mail storage servers. Online Chat uses a variety of clients, which vary depending on the chat protocol being used. Game Clients usually refer to the software that is the game in only multiplayer online games for the computer. Increasingly, existing large client applications are being switched to websites, making the browser a sort of universal client. This avoids the hassle of downloading a large piece of software onto any computer you want to use the application on. An example of this is the rise of Webmail . TYPES Clients are generally classified as either " Fat Client s", " Thin Client s", or " Hybrid Client s". Fat See Also: Fat client A fat client (also known as a '''thick client''' or '''rich client''') is a client that performs the bulk of any data processing operations itself, and does not necessarily rely on the Server . The fat client is most common in the form of a Personal Computer , as the personal computers or laptops can operate independently. Programming environments for rich clients include Curl , Delphi , Droplets , Java , Win32 and X11 . Thin See Also: Thin client A thin client is a minimal sort of client. Thin '''clients''' use the resources of the host computer. A thin client's job is generally just to graphically display pictures provided by an Application Server , which performs the bulk of any required data processing. Programming environments for thin clients include JavaScript / AJAX (client side automation), ASP , JSP , Ruby On Rails , Python's Django , PHP and other (depends on server-side backend and uses HTML pages or rich media like Flash, Flex or Silverlight on client). Hybrid See Also: Hybrid client A hybrid client is a mixture of the above two client models. Similar to a fat client, it processes locally, but relies on the server for storage data. This approach offers features from both the fat client (multimedia support, high performance) and the thin client (high manageability, flexibility).. SEE ALSO |
