thin client terminals serverThin Clients

A thin client is a computer (client) in client-server architecture networks which has little or no application logic, so it has to depend primarily on the central server for processing activities.

It may also be a program or a device for the execution of application programs.

In short, thin clients does most of its processing on a central server with as little hardware and software as possible at the users site.

A thin client's job is generally just to graphically display information from the application server. This allows a company the ease of managing their business logic for all applications at a central location.

Designing A Thin Client Network

In designing a client-server application, there is a decision to be made as to which parts of the task should be done on the client, and which on the server. This decision can crucially affect the cost of thin clients and servers, the robustness and security of the application as a whole, and the flexibility of the design to later modification or porting.


One design question is how application-specific the thin client software should be. Using standardized thin client software such as a Web browser or X11 display can save on development costs, since one does not need to develop a custom client—but one must accept the limitations of the standard client.Depending on the outcome of these decisions we might say that we use either one or both (or a mixture of both).



thin client software serverThin Client Terminals: "Thin client" has also been used as a marketing term for computer appliances designed to run thin client software. An X terminal, Wyse Winterm, Clearcube or Web kiosk might be considered thin clients in this sense.

Thin Client Software:There are also software-only thin clients which run on standard PC hardware or even on dedicated PCs as previously mentioned. The best example of this thin client software is PXES Universal Linux Thin Client and Pilotlinux.

A thin client may be a program or a device for the execution of thin-client application programs. Unfortunately, however, there is no precise definition (in quantifiable terms) for when the client program or device may be called a thin client or not.
