1) In a magnetic disk, sequential block numbers are placed next to one another on a track. Ex: Block 207 is placed after block 206. Is it true or false? justify your answer

3) For a direct-mapped cache design with a 32-bit address, the following bits of the address are used to access the cache (shown in the following table). Answer each of the following question:

	Tag	Index	Offset
a	31-10	9-5	4-0
b	31-12	11-6	5-0

What is the cache line size (in word) for a)?

What is the ratio between total bits required for such a cache implementation over the data storage bits for a)?

What is the cache line size (in word) for b)?

What is the ratio between total bits required for such a cache implementation over the data storage bits for b)?
