# who knows a easier way to understand binary?

need help with binary

Imagine Binary as an on off switch for a light bulb.

0 = OFF

1 = ON

So if we were to send the 8bit binary 10110000 to the light bulb switch it would go ON OFF ON ON OFF OFF OFF OFF.

So for example in your PC when binary code is sent to your hardware it is recieving an electrical current turning on and off different parts of the hardware.

Binary numbers are quite easy to remember as:

128 - 64 - 32 - 16 - 8 - 4 - 2 - 1

So for example 10110010:

128 - 64 - 32 - 16 - 8 - 4 - 2 - 1 1 - 0 - 1 - 1 - 0 - 0 - 1 - 0

10110010 = 128 + 32 + 16 + 2 = 178
