Detailed explanation-1: -The cache is faster, cheaper, and smaller than RAM. The cache memory caches CPU data and programs often and quickly. RAM contains the CPU’s current data and applications.
Detailed explanation-2: -A cache hit enables the processor to retrieve data quickly, making your overall system more efficient. Since cache memory is much smaller than server RAM, the data it stores is only temporary, and so it may not hold the information that the processor needs.
Detailed explanation-3: -The more cache memory a computer has, the faster it runs. However, because of its high-speed performance, cache memory is more expensive to build than RAM. Therefore, cache memory tends to be very small in size.
Detailed explanation-4: -Which statement is true for a cache memory? a)memory unit which communicates directly with the CPUb)provides backup storagec)a very high-speed memory to increase the speed of the processord)secondary storageCorrect answer is option ‘C’.
