A server is a computer that provides information to other computers called "clients" on a computer network. [1] 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 ...
Linux is the leading operating system on servers (over 96.4% of the top one million web servers' operating systems are Linux), [48] leads other big iron systems such as mainframe computers, [clarification needed] [49] and is used on all of the world's 500 fastest supercomputers [h] (as of November 2017, having gradually displaced all competitors).
Linux was designed by programmers for their own use, thus emphasizing simplicity and consistency, with a small number of basic elements that can be combined in nearly unlimited ways, and avoiding redundancy. [134] Its design is similar to other UNIX systems not using a microkernel. [135]
A Linux distribution is usually built around a package management system, which puts together the Linux kernel, free and open-source software, and occasionally some proprietary software. Many Linux distributions provide an installation system akin to that provided with other modern operating systems.
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.

Dedicated console server appliances are available from a number of manufacturers in many configurations, with the number of serial ports ranging from one to 96. These Console Servers are primarily used for secure remote access to Unix Servers, Linux Servers, switches, routers, firewalls, and any other device on the network with a console port.
On operating systems with a windowing system, such as macOS and desktop Linux distributions, some users may never use the shell directly. On Unix systems, the shell has historically been the implementation language of system startup scripts, including the program that starts a windowing system, configures networking, and many other essential ...
