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.
Overview of a three-tier application. Three-tier architecture is a client-server software architecture pattern in which the user interface (presentation), functional process logic ("business rules"), computer data storage and data access are developed and maintained as independent modules, most often on separate platforms. [15]
This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients or performing computations for a client. A single server can serve multiple clients, and a single client can use multiple servers.
HTML generated on the client can be added to the page using the standard DOM API (Line 6). Hop supports bidirectional communication between a running server and a running client instance through its standard library. The client connects to the WebSocket server through the standard HTML5 API (Line 5) and sends the current input value (Line 10).
Client is a computer that gets information from another computer called server in the context of client–server model of computer networks. [1] The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network.
The original server clients were simple text display terminals including Wyse VDUs, and rich clients were generally not used until the increase in PC usage.The original driving force for thin client computing was often cost; at a time when CRT terminals and PCs were relatively expensive, the thin-client–server architecture enabled the ability to deploy the desktop computing experience to ...
The REST architectural style is designed for network-based applications, specifically client-server applications. But more than that, it is designed for Internet-scale usage, so the coupling between the user agent (client) and the origin server must be as loose as possible to facilitate large-scale adoption.
client-server/2-tier (structural pattern): an application that consists of a front-end (user-facing) layer running as a rich client that communicates to a back-end (server) which provides business logic, workflow, integration and data services. In contrast to desktop applications (which are single-user), client-server applications are almost ...
