Question: A CPU contains

Answer:

A CPU, or central processing unit, is the primary component of a computer's processing power. It is a complex integrated circuit that contains several key components, including:

Arithmetic Logic Unit (ALU): This component performs arithmetic and logical operations, such as addition, subtraction, multiplication, and comparison.
Control Unit (CU): This component directs the flow of data and instructions between the various components of the CPU and the computer's memory.
Registers: These are small, high-speed memory locations within the CPU that are used to temporarily store data and instructions during processing.
Cache memory: This is a small amount of high-speed memory located within the CPU that is used to store frequently accessed data and instructions, in order to speed up processing.
Clock: The clock provides a timing signal to synchronize the operation of the CPU's components.
Instruction Decoder: This component decodes the instructions fetched from memory and determines the appropriate operation to be performed.
