what exactly is digital data?

Question

does it have a volume? if not how does it fill a memory chip? how does memory chips hold data? what EXACTLY is data? Is it electirc currents? is it a bunch of numbers that make a code?

Answer 1

memory holds two different charges (voltages) one is high, the other is low the high represents a 1 the low a 0. In a modern computers 32 of these ones and zeros are the contentes of a single memory location and represent a piece of data such as a letter of the alpahebet or a number.

In wndows go to start > run and type command
then type debug
then type d 100
and see for yourself

Answer 2

Data is basically information. This can mean a multitude of things depending on the context. Data at the binary level are 1's and 0's that represent information. 1's and 0's are stored on a memory chip as electrical currents. Voltage is used to determine whether the current represents a 1 or a 0.

Answer 3

0101010101001010101101010110101
That is digital data.
Interpreters or Programs reassemble the Binary code into working code. That is also called Compiling.
BASIC used a Text Code, but it was also very binary.
Look at The History of Computers, then UNIX, BASIC,DOS.

Answer 4

Data represented as discrete and discontinuous binary digits, as opposed to analog data which exists in continuous and variable form such as voltage, pressure, etc.
