Simply put, Yes!
The alternator basically is a unit that is turned through a belt, normally called the 'Fan Belt'. As it turns it produces an electrical charge which provides electricity which is stored in the car's battery.
If you have ever left your lights on overnight to find a flat battery in the morning, there is not enough charge or power in your battery to start the engine.
You use jumper cables which connect from one battery to the flat one which allows your battery to use the other as a 'slave'. once the car is started, you let it run for a while. During which time, the battery is re-charged by the alternator.
Back in the days of the Model T Ford, before the existence of alternators and battery technology, cars were started using crank handles. These cars didn't have alternators or electrical systems, so there was no battery to charge.
In summary, every modern gasoline/petrol and diesel engine needs an alternator to be able to keep the battery charged while driving.

Does your car have an alternator?
Yes, all modern cars have alternators.
Why do cars use alternators instead of generators?
Cars don't use generators because the batery is already generating energy. They use alternators in order to convert the energy generated into a usable form.
Are the alternators the same for the 1995 Camaro and the 1998 Camaros?
Physically, yes. However, where alternators differ, is in the produced, amps. If both cars have equal electrical amenities, then it will work.
Why do cars need alternators?
To keep the battery recharged and to help run all the electronics on the vehicle.
What does the alternator do for the car?
Alternators provide all the power for the vehicle as it is running. With newer cars, alternators are linked to the car's computer system, which many of the car's functions are evaluated from the voltage supplied by the alternator.
What is the difference between the welding current produced by alternator and the one produced by a generators?
Alternators produce Direct Current, Generators produce Alternating Current. Todays' cars have Alternators to charge the batteries.
What is the different between an alternator and a generator?
alternators are used in cars and generators are used for you know everything else
How is dc electricity formed?
It comes from batteries, dynamos and as rectified AC from alternators as are installed in cars and other vehicles.
Which cars have Lucas alternators on the right-hand side of the engine when viewed from the fan end?
My 1974 MG Midget has such an alternator.
If two cars are jumpered together for a long time will the alternators continue to charge the batteries normally?
Yes: provided that there are no underlying issues. What usually happens is that one of the two alternators does all the work while the other one coasts
