It is similar to how you have your house number.

Pointers hold reference to variable value which is already declared in memory.

How much more does the ipod weigh for each song?
Downloading a song into an idpod does not make it weigh any more. The song is written into the memory. And computer memory is only a change in the magnetic charge of a small memory byte. The memory chip does not change its physical characteristics. Computer memory is best illustrated by a group of light bulbs. A light bulb is turned ON for a value and turned OFF for another value. The combination of ON and OFF would equate to a number. The light bulbs didn't change weight. The difference with computer memory is that when one is turned "on", then it remains "on" without the requirement for more electric current.
