When learning how to Test and Tag a computer, you'll learn that there are essentially four items that need to be tested: the monitor, desktop PC and 2x IEC leads. Also, ensure the PC is shut down correctly before testing.
PC's are connected to the monitor via a VGA cable. As these cables are designed to shield themselves from electromagnetic interference, this shielding connects the earth of the desktop to earth of the monitor. As a result, testing a computer can be made easier because the 'earth return' lead does not have to be moved when testing the system.
