A digital signal is a physical signal that is a representation of a sequence of discrete values (a quantified discrete-time signal), for example of an arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal. The term digital signal can refer to either of the following:
A signal that is generated by means of a digital modulation method (digital passband transmission), to be transferred between modems, is in the first case considered as a digital signal, and in the second case as converted to an analog signal.

what do you mean by data assembly?
digital footprint means - data about you. Given by you and others from interactions in a digital world

DA means conversion of digital data into analogous and AD means conversion of analogous data into digital one.
An analogue-to-digital converter (ADC) is used to convert analogue data into digital data for the computer system to process. A digital-to-anagloue converter (DAC) is used to convert digital data back into analogue data for output.
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data

A digital system can recognize digital data i.e. data only in form of 0 & 1, if data is not in digital form we have to convert it using analog to digital converters.

process of representing data in digital form so it can be usedly a computer .
Digital data can exist in several forms. As a file, it will reside on a disc or in memory of some sort and as a stream, it will exist as a signal of some kind. Therefore, digital signals are made up of digital data. They are simply data that are being moved from one location to another. To convert file data to a digital signal, it is necessary for a process to be run that will take the data in a file and convert to a stream of data in the appropriate format.
