Question

Internally, the CPU consists of what two units?

Short answer

Answer: The two main units of a CPU are the Control Unit (CU) and the Arithmetic Logic Unit (ALU). The Control Unit manages and coordinates all hardware components, fetching, decoding, and executing instructions. The Arithmetic Logic Unit performs arithmetic and logical operations as per the decoded instructions.

Step-by-step solution

Identify the first unit of the CPU

The first main unit of a CPU is called the Control Unit (CU). The Control Unit manages and coordinates all of the hardware components in the computer. It is responsible for fetching instructions from memory, decoding them, and executing them. It also controls the flow of data within the system.

Identify the second unit of the CPU

The second main unit of a CPU is called the Arithmetic Logic Unit (ALU). The ALU is responsible for performing all the arithmetic and logical operations within the CPU, such as addition, subtraction, multiplication, division, and comparison of numbers. This unit processes the data according to the instructions that have been fetched by the Control Unit and decoded.

Conclude

To summarize, internally, the CPU consists of two main units: the Control Unit (CU) and the Arithmetic Logic Unit (ALU). The Control Unit manages the flow of instructions and data within the system, while the Arithmetic Logic Unit performs arithmetic and logical operations as per the decoded instructions.
