What is an Operating System?
The Operating System is a piece of software that controls all the resources
available in a computer and allows users utilize these resources. Operation Systems are what a computer needs to be available and in a way
defines our computing experience.
It's the first software we see when we turn on the computer, and the last software we see when the computer is turned off.
It's the software that enables all the programs we use. The operating system organizes and controls the hardware on
our desks and in our hands, yet most users can't say with any certainty precisely what it is that the operating system does.
Most of today's pc's and laptops are using a Windows based operating system such as Windows XP, Windows XP Professional, Windows 98, Windows 2000 and Windows 2003.
Depending on the tasks that a computer is assigned to do it needs different types of operating systems. For instance a Web Server needs a
special set of applications and specific form of usage from the resources of a computer. The operating systems such as Windows 2000 Server,
Windows 2000 Advanced Server, Windows 2003 Server which are all Server operating servers are designed to be installed on a Server Computers.
There are other operating systems designed for other types of computers such as MAC and SUN and Unix based systems.
