If u serve 2 months notice, they have to pay u 2 months of salary. U don't serve they don't have to pay. So it's the same. Usually people serve so that they can do a proper handover

Of course if you serve out the full 1 or 2 months notice, you don't have to pay, in fact you will still continue to get your salary.

If you wish to just leave immediately, you have to pay the company cash in lieu of notice.
