Q
What is the processor’s instruction set?
A
A set of instructions, individual to the processor, that it can carry out. The individuality means that one processors instruction set may not be compatible to anothers.
2
Q

A
Machine code.
3
Q
What are the two primary parts of machine code?
A
Opcode.
Operand.
4
Q

A
The type of operation that is to be carried out e.g. subtraction or store.
5
Q
Define an operand.
A
