Operating System:
The purpose of an operating system is to:
-Manage the Hardware & Software on a system
-To provide a stable, way for applications to run & perform tasks.
-Provide users with a Command Line or Graphical Interface (GUI) to interact with the computer.
System Requirements:
- Windows 2000 Professional:
-CPU: Pentium 133 MHz
-RAM: 64 mb
-HDD: 650 mb (Free Space)
-Windows XP: Home, Pro, Media Centre
-CPU: Pentium II 233 MHz
-RAM: 64 mb
-HDD: 1.5 GB (Free Space)
