What is the instruction set and how does the CPU use it?
The instruction set is a set of instructions that the CPU is designed to understand. The CPU fetches the instructions from the main memory and executes them repeatedly using the fetch-execute cycle.
Describe the role of the program counter in the fetch-execute cycle.
The program counter (pc) holds the memory address of the next instruction to be fetched from main memory. The CPU fetches the instructions one at a time from the main memory into the registers.
Explain the steps involved in executing the Python code 'area = length * width'.
First, the computer loads in the value of the variable length into the immediate access store (registers). Next it loads in the value of the variable width. Then it multiplies the two numbers together, and finally it stores the result in the variable area.
