Answer 2

In the case of a CPU cache, it is faster because it's on the same die as the processor. In other words, the requested data doesn't have to be bussed over to the processor; it's already there.

In the case of the cache on a hard drive, it's faster because it's in solid state memory, and not still on the rotating platters.

In the case of the cache on a web site, it's faster because the data has already been retrieved from the database (which, in some cases, could be located anywhere in the world).
