Operating systems
The role of an operating system is to link the hardware with the user
and any program running on the computer. The operating system has many
functions like the following:
-
Managing files – by copying, renaming, deleting
them and using folders.
-
Managing hardware – by loading programs, allocating
them resources, and using drivers to link specialist hardware such as a video
card.
-
Allocating resources – by sending keyboard/mouse
inputs to programs, as well as accesing other resources such as printing and
the hard disk.
-
Handling security issues, such as restore points
((to return system files and settings back to an earlier state), backups and
access to files when multiple used share a PC.
