Binary

Well , I study on Information and Communication Engineering.

So as far as I know ,

Computers are a Digital which contains only 2 number the 0 and 1 . or base 2 aka Binary.

These Binary are later represent the data such as 1 in ASCII Code are 00110001 .

and also In reality the computer itself is not on and off otherwise it will shutdown itself and it process.

It using High Voltage and Low Voltage , The High Voltage is 1 and Low Voltage is 0

Moreover , In terms of communication , Sending Data in Digital are more efficient than analog.

Because it use less power and less anotation over a distance due to it is only have 1 and 0 and it is a Discrete.

It easier and save power to use Decision Maker to check whether it is 1 and 0 and correct it and sending back

than the amplifier which use a lot of power to amplify the analog signal.

Also , In Computer , there is an error and/or exception happening every time but we didn't see it because it much likely handle by system itself . For Example , You hit the keyboard which you shouldn't when it do some processing and/or Someone sent you a packets over distance which is error - which most likely drop packets by your pc and waiting for retransmission and stuff

Back to the topic.

Q:Why do computers use the binary number system? A: Computers use the binary number system, or base 2, because they have two electrical circuits. On and off are the two electrical circuits used in the operation of a computer system.

May be it is a little off - topic.

but it would be a good knowledge to share with :D

Thanks
