Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Detailed explanation-1: -The CPU can only access its registers and main memory. It cannot, for example, make direct access to the hard drive, so any data stored there must first be transferred into the main memory chips before the CPU can work with it.
Detailed explanation-2: -cache memory, also called cache, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. The cache augments, and is an extension of, a computer’s main memory.
Detailed explanation-3: -A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations.
Detailed explanation-4: -Cache storage is a temporary storage like RAM. This is required because system RAM is slower and is a bit further away from the CPU, and all of this has a huge impact on performance and latency when data needs to be accessed frequently.
Detailed explanation-5: -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’.
