An Operating System (OS) is a collection of software that manages computer hardware resources. Without a computer operating system, a computer would be useless.
File management system is the manager in the OS that creates the illusion that there are files and folders being stored in computer memory.
I/O management : OS manages the input and output of all programs running under its control.
Memory management : It is responsible for the efficient usage of main memory, especially in a multiprogramming environment where processes contend for memory.
