What is computer binary numbering system?

Answer 1

We use a sytem that uses a base or 10, that is the numbers, 0 to 9, then we add a 1 to make 10 and start again 11,12,13 etc. The binary system uses a base of 2, like a switch on or off. so we get ;

Binary Decimal

0 0

1 1 now we have run out of numbers so we add another 1 to the left;

10 2

11 3 which is made up of a 2 and a 3; next we add another 1 to the left

and so on.

100 4

101 5

110 6

111 7 which is made up of a 4, a 2 and a 1

Thats it just keep going, every time we add a new 1 to hte left, its worth twice the value of the 1 to its right, its just like us using units, tens, hundreds thousands.

Answer 2

The binary system as it states is a number system of two ("bi-") which corresponds to the two states of a electrical/logic circuit: true/false, or more accurately: on/off.
