Answer / k.s.naidu
A system call is the mechanism used by an application
program to request service from the operating system.
On Unix-based and POSIX-based systems, popular system
calls are open, read, write, close, wait, exec, fork, exit,
and kill. Many of today's operating systems have hundreds of
system calls. For example, Linux has 319 different system
calls. FreeBSD has about the same (almost 330).
Tools such as strace and truss report the system calls made
by a running process.
