Client-Server Architecture

data multimedia web computers

Definition: The term client-server denotes a class of architectures for distributed systems, that is, a way of structuring and organizing the work of several computers that communicate through a network.

In a client-server system there is usually some kind of resource that that a number of other computers need to use. These resources can be of various kinds: from data that a number of computers need to have, to algorithms that they must execute. These resources are placed on a computer, the server, and the other computers that need to use them—the clients—send opportune requests to the server.

In multimedia, the problems that one has to deal with are usually connected to the size of multimedia data, so client-server systems for data distribution tend to be somewhat more common than those to access to computational resources. This tendency is complemented by the fact that typically in multimedia the computationally intensive applications have to do with the display of data, so that they have to be placed on the computer of the final user, which is typically a client. Computationally services that are provided in client server multimedia system are usually ancillary to data access, such as search services.

Many internet applications are organized in a client-server structure. A typical example is the world-wide web: browsers act as clients, sending requests for pages to the Web servers, who either retrieve the pages from their file system or perform the opportune operations to generate them, and send them to the client, which displays them to the user. (Quite ironically, in the software architecture sense, the world-wide web is not a web at all.)
