What are the three major components of a cpu

The three major components of cpu:

1. Operator

When the computer is running, the operation and type of operation of the operator are determined by the controller . The data processed by the arithmetic unit comes from the memory, and the processed result data is usually sent back to the memory or temporarily stored in the arithmetic unit. Together with ControlUnit, it forms the core part of the CPU.

2. Controller

The control unit is responsible for the process management of the program. Just like the logistics distribution department of a factory, the control unit is the command and control center of the entire CPU. It consists of three components: the instruction register IR, the instruction decoder ID, and the operation controller OC. It is extremely important for coordinating the orderly work of the entire computer.

3. Memory

The computer’s memory can be divided into internal memory and external memory. Internal memory is used frequently by the computer during program execution and is directly accessible during an instruction cycle.
