Parts of Unix Operating System:

The UNIX operating system comprises three parts: The kernel, the standard utility programs, and the system configuration files.



The kernel is the core of the UNIX operating system. Basically, the kernel is a large program that is loaded into memory when the machine is turned on, and it controls the allocation of hardware resources from that point forward.

Standard utility programs
These programs include simple utilities like cp, which copies files, and complex utilities, like the shell that allows you to issue commands to the operating system.

System configuration files:
The system configuration files are read by the kernel, and some of the standard utilities.
