System calls for process management

System calls for Process Management: 


1. fork(): A parent process uses fork to create a new child process. The child process is a copy of the parent. After fork, both parent and child executes the same program but in separate processes.

2. exec(): Replaces the program executed by a process. The child may use exec after a fork to replace the process’ memory space with a new program executable making the child execute a different program than the parent.

3. exit(): Terminates the process with an exit status.

4. wait(): The parent may use wait to suspend execution until a child terminates. Using wait the parent can obtain the exit status of a terminated child.
