Operating System
An operating system is the most important software on a computer. An operating system (OS)
is the software that manages a computer's hardware and software resources. It acts as a bridge
between the user and the hardware devices of the computer. Without an operating system, a
computer cannot work.
Types of Operating Systems
The most common operating systems for personal computers are Microsoft Windows,
Mac OS, and Linux. Other well-known names include UNIX and DOS.

hardware and software resources effectively.
