Which of these is not part of a central processing unit (CPU)?

Explanation:
A CPU is built from components that handle computing and fast data access: the arithmetic logic unit performs calculations, the control unit fetches and decodes instructions and coordinates data flow, and cache stores recently used data to speed up access. A disk drive, however, is a storage device used to keep data long-term. The CPU doesn’t execute from a disk directly; data must be loaded into RAM first, and the disk is accessed through I/O channels and controllers rather than as a core CPU component.
