Machine Code

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:

LDA #3000

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'.
