It manages hardware resources and ensures smooth
communication between components. The main types of
system software are Operating Systems, Device Drivers, and
Utility Software.

output devices, and network connections. Examples include Windows, macOS, Linux, Unix,
Android, and Ubuntu.
Device Drivers: A device driver is software that allows a computer to communicate with
hardware devices like printers and scanners. Without the correct driver, the device won’t work
