Cache Memory

 Cache Memory

Cache memory is a high-speed storage component that bridges the speed gap between the CPU and main memory (RAM). It temporarily stores frequently accessed data and instructions, enabling faster retrieval and boosting overall system performance.

• Location: Situated between the CPU and main memory (RAM).
• Size: Larger than registers, typically ranging from kilobytes to megabytes.
• Access Speed: Faster than main memory but slower than registers.
• Purpose: Acts as a buffer, storing frequently accessed data and instructions from main memory for quicker retrieval by the CPU.
• Benefits:
• Reduces the need to access slower main memory, boosting overall performance.
• Improves performance for programs or tasks that access the same data repeatedly.
• Drawbacks:
• Limited size compared to main memory, requiring careful selection of data to store.
• Data needs to be copied between cache and main memory, adding overhead.
