Binary And Denary
1=on 0=off, 101 we would read as on off on while a computer would read it completely differently.
Binary is base 2=computer
Denary is base 10=humans
Binary is kept basic so that the computer can understand it and read it much faster. Humans can do base 10 problems because we can work at a much faster rate and read it quicker than the computer.
Binary 8-bit goes up by x by 2 each time it goes up from 1.
The 8-bit system: 1,2,4,8,16,32,64,128.
Denary to Binary
To do this conversion pick a number under 255 (189)
Go through the list of numbers if the number goes into 189 then you put a 1 for 128
You then minus 128 from 189 and carry that number over (61)
If the number is smaller than the number its meant to go in (64) then you go onto the next number (32) and you put a 0 for 64.
You then repeat this process for other problems.
