Discuss various services provided by the operating system, Operating System

List and discuss the various services provided by the operating system.

Program execution - system capability to load a program into memory and to run it.
I/O operations - since user programs cannot execute I/O operations directly, the operating system must provide some means to perform I/O.
File-system manipulation - program capability to read, write, create, and delete files.

Communications - exchange of information between processes executing either on the same computer or on different systems tied together by a network.

Error detection - ensure correct computing by detecting errors in the

CPU and memory hardware, in I/O devices, or in user programs.
