Bits and bytes

Old computers use to have 6 bits to a byte, new ones usually have 8 bits to a byte.

Two states

All computers use two rules (base 2)

on/off

yes/no

1/0

true/false

current/no current

Changing whole numbers to binary

When changing numbers to binery with a base 2, if the answer is even put a 0 beside the sum, if the sum is odd put a 1 beside the sum.

2|26       26/2 =13 With 0 remaining (0 is next to the 13)

2|13  0   13/2= 6 With 1 remaining (1 is next to the 6)

2| 6   1    6/2=3 With none remaining …etc.

2| 3   0

2| 1   1

2| 0  1

Read the zeros and ones from bottom to top e.g. 11010

16| 8| 4| 2| 1|

  1| 1| 0| 1| 0|

Figuring out if it’s right is easy Just add up what the ones are under (16+8+2=26)

If it takes more than 5 ‘ones’ or ‘zeros’ to get the equation to zero the 1,2,4,8 etc. doubles each time 🙂
