16. Computers are not as smart as you think, in fact, they only know 2 things… 0 and 1 Everything else is told to the computer by a human, this is called programming. © Mrs G Hemel

17. Humans need to learn the computers language to be able to tell computers what to do. The computers language is Binary. Here is an example of what binary code looks like: 0101010001101000011010010111001100100000 0110100101110011001000000110010101100001 01110011011110010000110100001010 © Mrs G Hemel
