1.1.3 - Von Neumann Architecture

What is the name of the architecture all modern CPUs are based on?

Von Neumann Architecture

What are the 3 components of the CPU?

The three components of the CPU are the Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers.

What does the ALU perform?

• +, −, *, /

• comparisons

• boolean operators (AND, OR, NOT)

What is the purpose of the CU (Control Unit)?

The Control Unit transmits control signals to other components of the CPU. It follows the fetch-decode-execute cycle to execute program instructions.

What are the two main components of the CU?

The clock, which coordinates the CPU’s activity and the decoder, which decodes program instructions

What are registers?

Tiny amounts of super-quick memory within the CPU. Each register holds a specific piece of info.
