The 'system' API will run a command string in a subshell and return to the calling program. The 'execl' API will overlay the current process with a different program; it can never return to the calling program because the calling program is no longer there (it has been overlayed by the new program from execl).
The fork and exec command are used to spawn other activities or processes from a currently running program.
