Instructions & Programs: Crash Course Computer Science

The video tutorial explains the basics of CPU functionality, focusing on how CPUs are programmable and controlled by software. It covers a simple program execution using LOAD and ADD instructions, introduces advanced instructions like JUMP and JUMP_NEGATIVE, and discusses infinite loops. The tutorial also explains how conditional jumps can control program flow and logic. Finally, it highlights the limitations of instruction sets in hypothetical CPUs and provides a real-world example with the Intel 4004 processor.

How does the CPU differentiate between instructions and data in memory?

What are the two strategies modern CPUs use to handle instruction length?

Discuss the evolution of CPU instruction sets from the Intel 4004 to modern processors.
