Today's cars can often run on both regular and premium fuel. Some manufacturers recommend that their cars only use fuel with an octane level of 95 or higher. Note that recommend does not mean "must".
Most modern cars have sensors which can detect the type of fuel you use and will adjust the settings in the car's computer to control how your car runs on that particular type of fuel.
Using premium fuel decreases the chances of an engine knocking (pinging). To my ears, knocking sounds like marbles being rattled around in a plastic box. You can try to make your car knock by accelerating lightly uphill in a higher gear (3rd, 4th, 5th or 6th). Have the windows up and any other noisey accessories switched off to help listen out for it.
Is knocking bad for your engine? YES!!
