Cache memory is a small, high-speed storage located close to or within the CPU. Its primary purpose is to temporarily store frequently accessed data and instructions, reducing the time it takes for the CPU to access main memory. • Why cache memory is critical: Cache bridges the speed gap between the CPU and slower memory systems. By storing copies of frequently used data, it minimizes latency and enhances processing efficiency. The use of cache levels (L1, L2, and L3) ensures optimal performance for different workloads. For example, when a CPU processes a loop in a program, the loop instructions are repeatedly fetched. Without cache, the CPU would access the slower main memory every time, slowing down execution. ________________________________________ Why Other Options Are Incorrect: 1. Backup storage for the main memory: Cache is temporary and volatile, unlike backup storage, which is typically non-volatile. 2. Permanent data storage: Cache memory is volatile and cannot retain data after the system is powered off. 3. Facilitates communication between CPUs: Inter-CPU communication is handled by shared memory or interconnects like buses, not by cache memory. 4. Exclusive for storing user-defined variables: Cache stores both program instructions and data, not just user-defined variables.
