What are the main functions of process management in an operating system?


a) Create and delete user and system processes; Suspend and resume processes; Provide mechanisms for process synchronization; Provide mechanisms for process communication; Provide mechanisms for deadlock handling.
b) Maintain a record of the parts of memory that are currently being used and by which process; Decide which processes should be loaded into memory when space is available; Allocate and deallocate space in memory as necessary.
c) Create and delete files; Create and delete directories; Provide support for manipulating files and directories; Map files to secondary storage; Provide backup tools.
