Home > Client-side
In computer networking, the term client-side refers to operations that are performed by the client in a client-server relationship.Typically, a client is a software program, such as a web browser, that runs on a user's local computer or workstation and connects to a server as necessary. Operations may be performed client-side because they require access to information or functionality that is available on the client but not on the server, because the user needs to observe them or provide input, or because the server lacks the processing power to perform the operations in a timely manner for all of the clients it serves. Additionally, if operations can be performed by the client, without sending data over the network, they may take less time, use less bandwidth, and incur a lesser security risk.
When the server serves data in a commonly used manner, for example, according to the HTTP or FTP protocols, users may have their choice of a number of client programs (most modern web browsers can request and receive data using both of those protocols). In the case of more specialized applications, programmers may write their own server, client, and communications protocolIn networking, a communications protocol or network protocol is the specification of a set of rules for a particular type of communication. Different protocols often describe different aspects of a single communication; taken together, these form a protoc, that can only be used with one another.
Programs that run on a user's local computer without ever sending or receiving data over a network are not considered clients, and so the operations of such programs would not be considered client-side operations.

Distributed computingDistributed programming Distributed computing is the process of running a single computational task on more than one distinct computer. Introduction This differs from cluster computing in that computers in a distributed computing environment are typically projects such as SETI@home rely primarily on client-side operations. The SETI@home client initiates a connection with the server and requests some data. The server selects a data set (a server-sideIn computer networking, the term server-side refers to operations that are performed by the server in a client-server relationship. Typically, a server is a software program, such as a web server, that runs on a remote server, which is reachable by a user operation) and sends it back to the client. The client then analyzes the data (a client-side operation), and, when the analysis is complete, transmits its results back to the server.
