Question : Bandwidth definition with analogy needed

Hi
  Can anyone help me out with the definition of Bandwidth making use of a very simplified analogy that can drive the point home. I still get confused on this issue sometimes.

Answer : Bandwidth definition with analogy needed

Think about bandwidth as a trunk which can carry about 1000 kgm of cargo and transport them in one second
the more kgm you trunk can carry at a time the more quickly you can finish you job
so when we say you bandwidth is 1mbps it means that you can transport 1 mb per second into you wire
and when we say that your bandwidth is 2mbps it means that you can transport double the amount of data per second which will double your speed
the trunk is simply your wire , and the cargo is your data.
