1.	Can you get the process running for specific user
ps –u username

2.	What is system call
In computing, a system call is the programmatic way in which a computer program requests a service from the kernel of the operating system it is executed on. This may include hardware-related services (for example, accessing a hard disk drive), creation and execution of new processes, and communication with integral kernel services such as process scheduling. System calls provide an essential interface between a process and the operating system

3.	What is kernel panic
A kernel panic is a computer error from which the operating system (OS) cannot quickly or easily recover. The term applies primarily to Unix-based systems and to Mac OS X. In other systems, the equivalent of a kernel panic is known by slang terms such as blue screen of death, sad Mac or bomb

4.	Can u tell me how to check system call are being made by one process
