Multi-level caches introduce new design decisions. For instance, in some processors (like the Intel Pentium II, III, and 4, as well as most RISCs), the data in the L1 cache may also be in the L2 cache. These caches are called inclusive. Other processors (like the AMD Athlon) have exclusive caches — data is guaranteed to be in at most one of the L1 and L2 caches.

Some reading for you on Wiki. See under the Multi-level caches heading.

The real question is did you understand the above Do you know what caches are and why they are important?

OP, why are you asking? If this is for college, don't you think reading through your notes might be an idea?

Very simply put they enable your processor to work faster so you want the bigger the better.

Its kinda like having extra ram on your Processor which saves your processor going half way across your motherboard to use your Ram, it can just use its "cache" which is right beside it thus making it faster to process Applications etc

*VERY SIMPLIFIED SOLUTION and not entirely correct but I hope it will make it clearer for you.

If you need a more technical answer let me know and ill be more than happy to reply.
