In this lecture we will discuss modes of operating systems in detail as followed:
Operating System Modes:
The operating system code and user-defined code must be distinguished to ensure the proper execution of the operating system. Most of the computer systems Provide hardware support to differentiate among various modes of execution.
The two separate modes of the operating system include User-Mode and Kernel-Mode.
The kernel mode is also known as supervisor mode, system mode, or privileged Mode.
