When I try to start the engine, it makes a clicking sound each time that I turn the ignition key, but the engine won't start?

Yes, technology has moved on a bit. In the early days when you started the car the starter motor turned and "threw" a gear onto the flywheel to turn it. This was a brutal way to treat a gear, causing damage and failing to work properly. For many years now starter motors have been "Pre-engaged", so the gear is permanently attached to the flywheel, so doesn't get damaged. The click is the relay on the starter motor activating which. in turn, allows the motor to turn the engine. Starter motors take several hundred amps and need very clean connections at the battery, starter motor and a thick earth wire; if any of these connections are dirty the resistance will be sufficient to stop the motor turning the engine. If jump-starting it failed the cause could be dirty connections or a failed starter motor.
