Binary

The binary numeral system, or base-2 number system, represents numeric values using two symbols: 0 and 1. when 1 is used this indicates that something is there and if it is a 0 then nothing is there. when you have a number made from binary, each part is called a bit and if there are 4 bits in the number then it is a nibble. if you have 8 bits or 2 nibbles then it is a byte. when you have lots of binary code then it does start to get confusing because to work out the value you have to convert the binary into denary or decimal. think of it like this, on top of each bit there is a number that goes from 1 and each time you increase the amount of bits the value on top doubles. this makes it easier to understand.

Converting Binary to Denary / Decimal And adding!

The binary (base two) numeral system has two possible values, often represented as 0 or 1, for each place-value. In contrast, the decimal (base ten) numeral system has ten possible values (0,1,2,3,4,5,6,7,8, or 9) for each place-value. when you need to add binary it is quite simple. when you need to add 1 and 0 then it becomes 1. when you need to add 1 and 1 then it gets a bit more complicated. because binary only uses 1 and 0 then it is 1 but you need to carry 1 over to the next digit. say it was 1100 + 1010 then it would be:

1100

1010

=11110

because the last digits were both 1s then it is just like adding normal numbers where you don't carry you add it to the final number.
