Answer

Edit

During the fork() system call the Kernel makes a copy of the parent process's address space and attaches it to the child process.

But the vfork() system call do not makes any copy of the parent's address space, so it is faster than the fork() system call. The child process as a result of the vfork() system call executes exec() system call. The child process from vfork() system call executes in the parent's address space (this can overwrite the parent's data and stack ) which suspends the parent process until the child process exits.

When the system boots up, you can hear the fans start and the keyboard and drive lights flicker, but no display appears. What should you do first to troubleshoot this problem?

If the video problem produces a blank display, disconnect the monitor's signal cable from its video adapter card. If a raster appears, a video card problem is indicated.
