Explanation

The Control Unit directs all operations in the CPU.

The ALU (Arithmetic Logic Unit) performs arithmetic and logical operations.

Explanation

A complete microcomputer system includes a microprocessor (CPU), memory (RAM/ROM), and peripheral devices (keyboard, monitor, etc.).

All components work together to input, process, store, and output data.

Explanation

Every processor must have a Control Unit (CU) to direct operations and an Arithmetic Logic Unit (ALU) to perform calculations.

Primary storage (RAM) is essential for holding data and instructions during processing.

Explanation

Input, processing, output, and storage are the four primary components of the information processing cycle.

It is also known as the data processing cycle or the computer processing cycle.
