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.
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]
Binary Representation[edit]
Simple logic gates[edit]
Standards[edit]
* Outline the architecture of the central processing unit (CPU) and the functions of the arithmetic logic unit (ALU) and the control unit (CU) and the registers within the CPU. * Describe primary memory. * Explain the use of cache memory. * Explain the machine instruction cycle. * Identify the need for persistent storage. * Describe the main functions of an operating system. * Outline the use of a range of application software. * Identify common features of applications. * Define the terms: bit, byte, binary, denary/decimal, hexadecimal. * Outline the way in which data is represented in the computer. * Define the Boolean operators: AND, OR, NOT, NAND, NOR and XOR. * Construct truth tables using the above operators. * Construct a logic diagram using AND, OR, NOT, NAND, NOR and XOR gates.
