I have a couple of questions on Linux please help me

1. which process is the parent process of all the processes in Linux?
2.How the system calls are getting called?
3. If there are different terminals attached to the system the if more than one terminals are using vi, then they are different copies or the same copy of vi will be runned in all the terminals?

Thanks in advance.

1. init with pid=1
2. System calls are getting called by the shell.
3. they are different instances of vi on different copies of the same file in the different terminals.
