Computer Organization[1]
How does a cpu actually work?
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]
- Operating system
- Application software
- File systems (not required by IB)
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.
