Study Notes

CPU Components and Functions

The Arithmetic Logic Unit (ALU) performs arithmetic and logical operations, such as addition, subtraction, AND, OR, and NOT.

CPU Cores

Most CPU models typically have four cores.
A CPU core is the processing unit that executes instructions and performs calculations.

Control Unit (CU) Role

The Control Unit (CU) retrieves and decodes instructions, generates control signals to execute instructions, and manages data transfer between CPU components.

Central Processing Unit (CPU) Function

The Central Processing Unit (CPU) executes instructions and performs calculations, controlling the flow of data between different parts of the computer.

Multi-Core Processors

Multi-core processors became popular due to the need for increased processing power and efficiency.

CPU Components

The CPU includes the Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers.

Intel Processor Names

The numbers (i3, i5, i7) in Intel processor names represent different levels of processing power, with i7 being the highest.

CPU Primary Function

The CPU primarily performs calculations, executes instructions, and manages data transfer between different parts of the computer.
