Digitizing or digitization<ref>Also known as digitising or digitisation, digitalizing or digitalization; see American and British English spelling differences. NB not digitalising or digitalisation (thefreedictionary.com)</ref> is the representation of an object, image, sound, document or signal (usually an analog signal) by generating a series of numbers that describe a discrete set of its points or samples. The result is called digital representation or, more specifically, a digital image, for the object, and digital form, for the signal. In modern practice, the digitized data is in the form of binary numbers, which facilitate computer processing and other operations, but strictly speaking, digitizing simply means the conversion of analog source material into a numerical format; the decimal or any other number system can be used instead.

Digitization is of crucial importance to data processing, storage and transmission, because it "allows information of all kinds in all formats to be carried with the same efficiency and also intermingled".<ref>McQuail, D (2000) McQuail's Mass Communication Theory (4th edition), Sage, London, pp. 16-34</ref> Unlike analog data, which typically suffers some loss of quality each time it is copied or transmitted, digital data can, in theory, be propagated indefinitely with absolutely no degradation.
