Which among the following is incorrect about cache memory?

Correct option is A

The statement "It is slower than the main memory" is incorrect because cache memory is much faster than the main memory (RAM). Cache memory is designed to provide high-speed access to frequently used data and instructions, thereby reducing the time the CPU spends waiting for data from the main memory.

Important Key Points:

1. Cache memory is faster than main memory but smaller in size.
2. It acts as a high-speed buffer between the CPU and main memory to store frequently accessed data.
3. Data stored in cache is for temporary use, improving the system's performance by reducing latency.

Knowledge Booster:

• Cache memory keeps frequently used programs and instructions close to the CPU to minimize data fetch time.
• It serves as a critical component for performance optimization in modern computing systems.
• While main memory is larger and slower, cache provides faster access for critical data processing.
