c) Operation/price ratio
d) None of the mentioned
4. The performance depends on
a) The speed of execution only
b) The speed of fetch and execution
c) The speed of fetch only
d) The hardware of the system only
5. The main purpose of having memory hierarchy is to
a) Reduce access time
b) Provide large capacity
c) Reduce propagation time
d) Reduce access time & Provide large capacity
6. The memory transfers between two variable speed devices is always done at the speed of the faster device.
7. An effective to introduce parallelism in memory access is by _______
a) Memory interleaving
8. The performance of the system is greatly influenced by increasing the level 1 cache.
Explanation: This is so because the L1 cache is onboard the processor.
