What is memory hierarchy, and why is it important in computer systems? Describe the main levels of memory in a typical hierarchy.
Expert Solution
Step 1: Define Memory hierarchy
Memory hierarchy involves organizing different types of memory devices in a system to optimize the balance between performance, capacity, and cost. The primary goal is to provide fast and efficient data access to the CPU while managing the trade-offs between speed, capacity, and cost effectively. In a computer system, the memory hierarchy consists of several levels, each with distinct characteristics and purposes. These levels are arranged in a hierarchy, with each level being larger and slower but also more cost-effective than the level above it.
