Computer Organization^[1]

A computer is an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.^[2]

Computer architecture[edit]

Secondary memory[edit]

Persistent storage

Operating systems and application systems[edit]

Binary Representation[edit]

Simple logic gates[edit]

Not part of IB curriculum but you should know this[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.
