Whereas the words server and client may refer either to a computer or to a computer program, server-host and client-host always refer to computers. The host is a versatile, multifunction computer; clients and servers are just programs that run on a host. In the client–server model, a server is more likely to be devoted to the task of serving.
A thick client, also known as a rich client or fat client, is a client that performs the bulk of any data processing operations itself, and does not necessarily rely on the server. The personal computer is a common example of a fat client, because of its relatively large set of features and capabilities and its light reliance upon a server. For ...
Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server. While request–response is the most common client-server design, there are others, such as the publish–subscribe pattern. In the publish-subscribe pattern, clients register with a pub-sub server, subscribing to ...
A host is a node that participates in user applications, either as a server, client, or both. A server is a type of host that offers resources to the other hosts. Typically a server accepts connections from clients who request a service function. [4] Every network host is a node, but not every network node is a host.
In computer networking, a thin client, sometimes called slim client or lean client, is a simple (low-performance) computer that has been optimized for establishing a remote connection with a server-based computing environment. They are sometimes known as network computers, or in their simplest form as zero clients.
Client/server distributed networking is also popular in web-based computing. [3] Client/Server is the principle that a client computer can provide certain capabilities for a user and request others from other computers that provide services for the clients. The Web's Hypertext Transfer Protocol is basically all client/server. [1] [4] [5] [6]
Sometimes the more general term server or server process is used, particularly for daemons that operate as part of client-server systems. [5] After the term was adopted for computer use, it was rationalized as a backronym for Disk And Execution MONitor. [6] [1] Daemons that connect to a computer network are examples of network services.
Cloud computing attempts to address QoS (quality of service) and reliability problems of other grid computing models. [77] Cloud computing shares characteristics with: Client–server model – Client–server computing refers broadly to any distributed application that distinguishes between service providers (servers) and service requestors ...
