simply that. It supplies power.
Now, in a computer, it takes in power from the wall (or from the battery) and then supplies the proper voltage and power to those parts which need it.

Uh... it's a device that supplies power?
Typically a power supply is a transformer to take 120V/220V in put and step it down to another voltage. Not uncommon to make the output DC as well. Most common example: the power supply in a desktop computer takes wall current and provides +/-5V and +/-12V DC.

It's usually a device that converts standard electricity from a wall plug (110VAC or 220VAC, depending on which country you're in) to a lower voltage direct current that the electronic device uses. Most computer circuts run on 5V DC or 10V DC, and most of your other household gadgets run on anything from 1.5V DC to 18V DC.
