So, computers use binary numbers to represent everything inside them. Computer instructions at the machine level are composed of binary numbers that direct the computer to perform actions.
The instruction must tell the computer what to do (add, move, decision, etc.), what to use (which data to use), where to put the results, etc. Don't stop here, DATA or information is also represented as binary 1's and 0's; but they are sets of specific bit combinations for representing a set of characters.
