This document provides a diagram of the main components of a CPU, including the processor, cache, main memory, input and output devices. It also describes the fetch-execute cycle where the CPU fetches code from memory, decodes the binary instructions, and executes the instructions by directing the arithmetic logic unit. The control unit manages data flow and communication between the CPU components.

2. The fetch Execute Cycle
Fetches the item from
the memory or
storage
Decodes the code
which is 1’s and 0’s
It then executes
what the code told it
to do

3. Control unit
Inputs and Outputs
Immediate access store
Backing store
Arithmetic & logic unit
(ALU)
