When a CPU executes instructions as it converts input into output, it does so with _____.
A) the control unit and the arithmetic logic unit
B) the hard drive and RAM
C) the cache and the motherboard
D) RAM and ROM

Question

Quizplus · Accepted Answer

The control unit and the arithmetic logic unit (ALU) are the two main components in a CPU. The control unit fetches instructions from memory and coordinates the actions of the other components, while the ALU performs arithmetic and logical operations on data. Together, they execute instructions and process input into output. The hard drive, RAM, cache, and motherboard are all important components in a computer, but they do not directly execute instructions like the control unit and ALU. RAM and ROM are types of memory that do play a role in the CPU's operation, but they are not the only components involved.
