You have created a new storage space using a single 500 GB external USB 3.0 drive. The drive is becoming full, so you add another external 1 TB USB 2.0 drive to the storage pool. Now that you have two drives, you would like to create a volume with storage space resiliency set to two-way mirror. You create the new volume with two-way resiliency and a size limit of 1 TB. As you are copying files from the C: drive to this new volume, you receive a warning that you are running out of space. Only a few hundred megabytes have been copied; why might you be receiving the warning so quickly? What can you do about it?

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?

You draw two cards from a standard deck of 52 cards, but before you draw the second card, you put the first one back and reshuffle the deck. (a) are the outcomes on the two cards independent? why?
