120V is the voltage of electricity (amount of power it contains). In Canada, USA and most of North America, we use 120V electricity. On the other hand, the rest of the world uses 220V (more powerful).
60Hz is the frequency of the electricity. Believe it or not, when you turn on a light bulb, you don't see a straight beam of light. The light is actually flickering on and off 60 times a second (too fast for the eye to see). In Europe, the frequency is 50Hz (Asia is mostly 60Hz, at least I know China uses 60Hz).
2.1A is the amount of power that the PS3 console draws from the electrical socket. You might have heard of something like a 60W or 100W light bulb. Watts is also how much electricity something consumes. To get the wattage from "A" which stands for amps, multiply the volt (120) by the amp (2.1) and divide by 1000
PS3 uses around 250W of electricity per hour.
And that's basically it. You'll learn it in science class if you haven't already :)

It is the plug type that is used for the unit.
It tells you that the device uses a 120 Volts- 2.1 amps @ 60 Hertz.
It also tells you what connector you can use,
