About Sysadmins
According to Wikipedia's article on system administrators:
A system administrator, or sysadmin, is a person employed to maintain, and operate a computer system or network for a company or other organization. System administrators are often members of an information technology department.
The duties of a system administrator are wide-ranging, and vary widely from one organization to another. Sysadmins are usually charged with installing, supporting, and maintaining servers or other computer systems, and planning for and responding to service outages and other problems. Other duties may include scripting or light programming, project management for systems-related projects, supervising or training computer operators, and being the equivalent of a handyman for computer problems beyond the knowledge of technical support staff.
