A(n) is special high-speed memory that allows a microprocessor to access data more rapidly than from memory located elsewhere on the system board.

Answer is CPU cache

Explanation: A CPU cache is a special high-speed memory which is smaller and faster, and which helps to store copies of data from main memory location which are often used. It is actually located quite close to the processing core, and is used by the CPU of a computer to save time and energy in accessing data from the main memory.

The way it works is if the processor is either trying to read from or write to a particular location in the main memory, it checks to see if the data from the location is already in a cache, if it is, then it alternatively read from or write to the cache; which faster, instead of the main memory.

Please let me know if this helps.

Cache memory in CPU.

Explanation:

The computer system is an electronic device comprising of a hardware unit and a software interface unit or platform. The software unit provides the user with the interface to operate the system, while the hardware is the physical parts of the system.

The hardware components are the input and output unit, the CPU and the memory. For a cpu to process a task or data, it retrieves it from the memory, which can be very slow as more data are retrieved for every computing.

The cache memory is an built-in memory in the CPU that can retrieve data for computing. It boost the speed of CPU operation by providing the retrieved data speedily to the CPU.

answer; (c) series 3; i believe this is the correct answer. good luck
