Because the switches that are used are usually on/off switches. Notice: on + off = two settings. Binary = Two digits. To get something digital and non-binary (for example, trinary) you would need a switch that can be "on", "off", and "sort of on". In addition, you wold need logic gates that support this "sort of on" setting.
All electronic devices use digital communications, which is binary.
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
For most digital computers at the lowest level, they work in binary. Experimental multilevel computers have been built and analogue computers don't work in binary.
5.6 V is within the range that most digital circuits recognize as a binary "1".
It has to do with the way computers are built at their core. At the base level it all comes down to on or off. Binary is perfect for that. 0 = off, 1 = on.
Digital
It already has; binary.
Everything "digital" or that is computer based.
it is a sequence of 1s and 0s. (binary) :)
digital
i think its called binary.
Bit means 'Binary Digit' In a Digital Circuit, the amount of 'bits' is usually the measure of binary digits which can logically be processed. 8 bits per byte.
