1.	Which statement is true for a cache memory?(a) memory unit which communicates directly with the CPU(b) provides backup storage(c) a very high-speed memory to increase the speed of the processor(d) secondary storageThis question was addressed to me during a job interview.The question is from Memory Organisation of Embedded Systems in division Memory Systems of Embedded Systems
Answer» CORRECT answer is (c) a very high-SPEED MEMORY to increase the speed of the processor The best EXPLANATION: The RAM is the primary storage which directly communicates with the CPU. ROM is the secondary storage. Disk drives are capable of providing backup storage and the cache memory is a small high-speed memory which increases the speed of the processor.
