LINUX - System / Server Administration

A server administrator, or admin has the overall control of a server. This is usually in the context of a business organization, where a server administrator oversees the performance and condition of multiple servers in the business organization, or it can be in the context of a single person running a game server.

The Server Administrator's role is to design, install, administer, and optimize company servers and related components to achieve high performance of the various business functions supported by the servers as necessary.

This includes ensuring the availability of client/server applications, configuring all new implementations, and developing processes and procedures for ongoing management of the server environment.

A Linux server is a high-powered variant of the Linux open source operating system. The responsibilities of a system administrator and network administrator often overlap; however, the system administrator is more geared to the computer hardware and less on the network, although in many cases, system and network administrator are one in the same, especially in smaller companies.

Linux is an operating system like MS Windows, which allow software programs ("application software") to interact with the computer. An operating system makes the computer hardware (say, a microprocessor) understand the commands of application software and gets the job done.

Server/system administration of Linux is all about keeping a Linux-based computer in usable order. Administration involves functions like backing up files, installing new programs, creating or deleting user accounts, making certain that the filesystem is not corrupted, and so on. In short, if a computer were a house, system administration would be can be likened to maintenance - things like cleaning, fixing broken windows, etc.
