A-level Computing/AQA/Paper 2/Fundamentals of computer organisation and architecture/Addressing modes
There are many different addressing modes which can be used. However, in the AQA A-level there are only two that need to be known - Direct and Immediate.
Immediate Addressing
Immediate addressing is where the value is passed directly as the operand. In AQA assembly this is shown using the # symbol.
Direct Addressing
Direct addressing is where the address at which the value is stored is the operand.
