Question: 1 / 400

What advantage does cache memory provide?

Slower access to stored data

Extended data storage capacity

Faster access for program sections and data

Cache memory provides the advantage of faster access for program sections and data. It is designed to store frequently accessed data and instructions closer to the processor than main memory (RAM). This close proximity reduces the time it takes for the CPU to retrieve information since accessing cache memory is significantly quicker than accessing data from slower main memory. By minimizing access times, cache memory improves overall system performance and efficiency, allowing programs to run more smoothly and efficiently.

The other choices do not correctly reflect the primary benefits of cache memory, as they either imply drawbacks or do not accurately convey the primary purpose of cache memory.
