Memory Hierarchy
Memory Hierarchy refers to the arrangement of different types of memory in a computer system in a hierarchical order based on their speed, size, and cost. The memory hierarchy consists of multiple levels of memory, each with different characteristics and purposes. The levels of memory hierarchy include registers, cache memory, main memory (RAM), secondary memory (hard disk), and tertiary memory (tape drives). The primary goal of the memory hierarchy is to provide the CPU with the fastest possible memory access while minimizing the overall cost of the memory system. The memory hierarchy is an essential concept in computer architecture and plays a crucial role in determining the performance of a computer system.
