Question

which one of the following system calls blocks the entire process in many to one model options are 1. exec system call 2.bloxk system call 3.half system call 4.fork system call​

Answer 1

Fork system call is used for creating a new process, which is called child process, which runs concurrently with the process that makes the fork() call (parent process). After a new child process is created, both processes will execute the next instruction following the fork() system call. A child process uses the same pc(program counter), same CPU registers, same open files which use in the parent process.
