Operating System
An operating system is a series of programs which organizes and controls a computer. Every computer comes with one set of programs already on it’s hard drive. The operating system is the most important of those programs. When the computer is turned on, the operating system tells it what gadgets are linked to the computer. The operating system, or OS, controls the hardware (keyboard, mouse, printer) and it controls the operation of the software.
We still have some older computers in our school that are running on OS 9. These are mostly the extra, student computers in the classrooms. The newer computers use OS X (10) but they also have OS 9 built into them so you can still use some older software that needs 9 to work. Operating system 9 is also called “classic”.
