A server is a system that responds to requests across a network to provide services. Servers can run on dedicated computers or networked computers. Any computerized process that shares resources to clients is considered a server. While a laptop is not typically thought of as a server, it can fulfill the server role by running server software like a web server. Servers prioritize fast network connections and input/output throughput over absolute CPU speed. Servers often run without monitors or input devices and exclude unnecessary processes to allocate resources to their functions.
Server and Its Types - Presentation
- 3. A server is a system (software and suitable computer hardware) that responds to requests across a computer network to provide, or help to provide, a network service. Servers can be run on a dedicated computer, which is also often referred to as "the server", but many networked computers are capable of hosting servers. In many cases, a computer can provide several services and have several servers running.
- 4. The term server is used quite broadly in information technology. Despite the many server-branded products available (such as server versions of hardware, software or operating systems), in theory any computerized process that shares a resource to one or more client processes is a server. To illustrate this, take the common example of file sharing. While the existence of files on a machine does not classify it as a server, the mechanism which shares these files to clients by the operating system is the server.
- 5. Similarly, consider a web server application (such as the multiplatform "Apache HTTP Server"). This web server software can be run on any capable computer. For example, while a laptop or personal computer is not typically known as a server, they can in these situations fulfill the role of one, and hence be labeled as one. It is, in this case, the machine's role that places it in the category of server.
- 6. Hardware requirement for servers vary, depending on the server application. Absolute CPU speed is not quite as critical to a server as it is to a desktop machine. Servers' duties to provide service to many users over a network lead to different requirements such as fast network connections and high I/O throughout. Since servers are usually accessed over a network, they may run in headless mode without a monitor or input device. Processes that are not needed for the server's function are not used. Many servers do not have a graphical user interface (GUI) as it is unnecessary and consumes resources that could be allocated elsewhere. Similarly, audio and USB interfaces may be omitted.
- 7. In the client/server programming model, a server is a program that awaits and fulfills requests from client programs in the same or other computers. A given application in a computer may function as a client with requests for services from other programs and also as a server of requests from other programs. Specific to the Web, a web server is the computer program (housed in a computer) that serves requested html pages or files. A Web client is the requesting program associated with the user. The Web Browser in your computer is a client that requests HTML files from Web servers.
- 8. Application server a server dedicated to running certain software applications Catalog server a central search point for information across a distributed network Communications server carrier-grade computing platform for communications networks Compute server, a server intended for intensive (esp. scientific) computations Database server provides database services to other computer programs or computers Fax server provides fax services for clients File server provides remote access to files Game server a server that video game clients connect to in order to play online together
- 9. Home server a server for the home Mail server handles transport of and access to email Mobile Server or Server on the Go is an Intel Xeon processor based server class laptop form factor computer. Name server or DNS Print server provides printer services Proxy server acts as an intermediary for requests from clients seeking resources from other servers Sound server provides multimedia broadcasting, streaming. Stand-alone server a server on a Windows network that neither belongs to nor governs a Windows domain Web server a server that HTTP clients connect to in order to send commands and receive responses along with data contents
- 10. Server-oriented operating systems can, in many cases, interact with hardware sensors to detect conditions such as overheating, processor and disk failure, and consequently alert an operator or take remedial measures themselves.
