Question

Which memory type can provide a CPU with the fastest access to frequently used data?

1) Cache memory
2) RAM
3) Hard disk
4) Optical disk

Answer 1

Correct answer is A) .Cache memory offers the fastest access for frequently used data due to its proximity to the CPU, enabling quicker access times and improving system efficiency.

Step-by-step explanation:

The memory type that can provide a CPU with the fastest access to frequently used data is cache memory.

Cache memory is a small and fast memory that is located directly on the CPU or within close proximity to it. It stores frequently used instructions and data so that the CPU can access them quickly without having to wait for data to be fetched from slower memory types like RAM, hard disk, or optical disk.

For example, when a CPU needs to fetch data for processing, it first checks the cache memory. If the data is found in the cache, it is retrieved quickly, providing fast access. However, if the data is not found in the cache, the CPU has to fetch it from RAM, which takes more time.
