Introduction


In this section I tried to give answers to the following questions:

What is Systems Administration?

System Administration is the set of all tasks to do until a network of computers is customized so that every user of that computer network can do the work s/he is supposed or willing to.
According to that definition, System Administration is an impossible task.

What does System Administration consist of?

Normally, a System Administrator (short: SysAdmin) has to perform the following tasks:
  • install the operating system and its utilities
  • install standard software
  • help the users to work efficiently with that software
  • fix software defects
  • assist the users with the usage of printers, scanners, etc.
  • configure a network, all computers therein and the network equipment
  • fix hardware defects
  • analyze the performance of the computer system and to contribute to that with proposing possible inprovements
The first five of the items above are "proper" system administration tasks and will be covered here. Networking is a course on its own, as is the hardware issue. The last item is most often referred to as "System Analysis".

Why hiring System Administration's specialists?

Normally, everyone that operates a computer has to have some of the SysAdmin's knowledge. So why cannot everyone configure his computer on his own?
The first reason is that it is an enormous waste of time and efforts if every user must get into systems administration; under these circumstances a user tends to spend more time on configuring his/her system than on his very work.
The second reason is that there are many tasks that can be done efficiently only if one employee is responsible for all the computer equipment; things like development of a general backup strategy or decision over what operating system to use are normally out of the sight of the middle-of-the-road user.
