"Does your computer have cache? Yes
If so how big is it? 2 x 4MB = 8MB
How does your cache size compare with the size of main memory?
CM is 8MB and MM is 8GB
Do you know what kind of cache it is? No
How did you find out about your computer's cache? I looked up the specs for an Intel Q6600.
Make an assumption that your cache is either:
Fully associative
Direct mapped
Two-way set-associative
Four-way set-associative
Based on the assumption that you made, what is the layout of the bits in each cache word, i.e. tag(s) + data + valid bit(s)
If necessary you may also make an assumption on the size of a word.
