WebMain memory is slower than cache memory due to its higher latency, longer access time, and the difference in the technology used to build them. Caches are designed to bridge the speed gap between the processor and main memory, by storing frequently used data closer to the processor and providing faster access times. WebCache memory stores the portion of programs currently getting executed in CPU and any temporary data needed for computation. It acts as a buffer between CPU and main memory. This is the reason cache memory is important and highly needed. The above CPU and main memory speed disparity is popularly known as Von-neumann bottleneck. iphone 13 pro handyhülle
