One of my roommates has a question on computer architecture that has me completely stumped. So without further ado I'll have him post it.

Hello. Does anyone know why set associative mapping is better than direct mapping in cache memory? Thanks in advance. BTW my nick is monty but I'm waiting on email confirmation on it.

Beta: Can you pass on these links to your friend, I hope they'll be helpful:

This one basically defines the mapping methods (direct, fully associative, n-way associative/set associative)

This next one compares the performance between the three
