Why caches are useful and what problems do they cause?

Caches are useful because they can increase the speed of the average memory access, and they do so without taking up as much physical space as the lower elements of the memory hierarchy. They ameliorate the (performance critical) memory access time by leveraging spatial and temporal locality.

What is the impact of the cache on overall performance of the computer system?

The more cache there is, the more data can be stored closer to the CPU. Cache memory is beneficial because: Cache memory holds frequently used instructions/data which the processor may require next and it is faster access memory than RAM, since it is on the same chip as the processor.
