3. Operating System Purpose
3 main purposes:
To provide an environment for a computer user to execute programs on computer hardware in a convenient and efficient manner
(Shells, Windows, Terminals, Executable files concept).
To allocate separate resources (memory, processor, disk space, I/O device usage) of the computer as needed to solve the problem given.
The allocation process should be as fair and efficient as possible.
Control the running programs:
supervision of the execution of user programs to prevent errors and improper use of the computer
protection of OS and programs from user programs
management of the operation and control of I/O devices
device drivers, file systems
