Systems administration is the installation and maintenance of the UNIX computer system. The system administrator will need to maintain the software and hardware for the system. This includes hardware configuration, software installation, reconfiguration of the kernel, networking, and anything else that's required to make the system work and keep it running in a satisfactory manner. To do this the system administrator can assume superuser, or root, privileges to perform many tasks not normally available to the average user of the system.
