4) A group of very fast memory chips located within the CPU that contain data and instructions that the CPU may need next is (are) called .

Cache Memory

Explanation:

Cache memory is the fastest type of memory in a computer system. It resides outside the CPU and is found one level below it. Therefore, we have to consider cache memory as an external memory that is outside of the CPU that has a very fast access speed. All recent program instructions are always stored in cache memory for ease of access. Whatever instructions the CPU needs to process will be taken first from the cache memory before performing its operations. The cache was built to reduce the access time.
