At the very lowest level of operation a computer follows binary instructions.
Binary looks like this: 10100111 01001011 10011001 110100100
This does not make sense to people having to program at this level. So a slightly more people-friendly language is used called 'Machine Code' and it looks like this:
STO E, A
Another name for machine code is 'Assembly Language'.
Machine code tells the microprocessor step by step what to do. For example "Move data from register A to Register B.
Every microprocessor has its own set of machine code called its 'Instruction Set'.
