Computer organization
Computer Organization[1]
How does a computer actually work? How do they transform what you type into a program that shows cute cat pictures?
Big ideas in computer organization[edit]
This lecture (quite long) is an excellent introduction to the deeper ideas presented on this page. I strongly advise you to watch this.
Information layer[2][edit]
Computer architecture[edit]
- Architecture of the central processing unit (CPU)
- Functions of the arithmetic logic unit (ALU)
- Control unit (CU)
- Registers within the CPU
- Primary memory
- Cache memory
- The machine instruction cycle
Secondary memory[edit]
Operating systems and application systems[edit]
Simple logic gates[edit]
Textbook pages[edit]
