The _______ performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.

The _______ performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.

• A. Central Processing Unit
• B. Random Access Memory
• C. Graphics Processing Unit
• D. Motherboard

Answer: (A)

The central processing unit is what executes the instructions of a program. It contains the arithmetic-logic unit to perform basic math and logic operations, and a control unit that sequences those operations so the program runs in the correct order. It also coordinates input/output by issuing the necessary signals to devices and controllers as dictated by the instructions. Memory, like random access memory, stores data and instructions but doesn’t carry out computation. A graphics processing unit specializes in graphics-related parallel tasks rather than general-purpose instruction execution. The motherboard is the main circuit board that connects components, not the component that executes instructions.
