What is a System Administrator?
System Administrators are technical professionals responsible for the support, maintenance and development of computer systems.
System Administrators typically install new hardware and software, as well as troubleshooting existing systems. They generally taking care of the computers which are now largely responsible for keeping many businesses afloat. In some ways, everybody who uses a computer is a system administrator - keeping an eye on the disc space they have, rebooting their PC when problems occur, and storing backups of important files on floppy disc in case of disaster.
Professional system administrators, however, often look after large numbers of computers and networks - they are the people who keep the systems running, repair faulty discs, install and debug new software, upgrade existing systems, and generally take care of the computing resources needed for their users to perform their tasks effectively. A shorter definition is "A system administrator is one who manages computers not solely for his or her own use".
