These are known as bits (a contraction of binary digits) and the sequences of 0s and 1s that constitute information are called bytes. The core of the process is the compromise between the capturing device and the player device so that the rendered result represents the original source with the most possible fidelity, and the advantage of digitization is the speed and accuracy in which this form of information can be transmitted with no degradation compared with analog information.ĭigital information exists as one of two digits, either 0 or 1. The term digitization is often used when diverse forms of information, such as an object, text, sound, image, or voice, are converted into a single binary code. Professionals in the field can attend conferences and join organizations and working groups to keep their knowledge current and add to the conversation. Technological changes can happen often and quickly, so digitization standards are difficult to keep updated. Mass digitization projects have had mixed results over the years, but some institutions have had success even if not in the traditional Google Books model. Many digitizing institutions develop their own solutions to these challenges. There are challenges and implications surrounding digitization including time, cost, cultural history concerns, and creating an equitable platform for historically marginalized voices. Some analog materials, such as audio and video tapes, are nearing the end of their life-cycle, and it is important to digitize them before equipment obsolescence and media deterioration makes the data irretrievable. Doing this creates challenges for information professionals and solutions can be as varied as the institutions that implement them. Libraries, archives, museums, and other memory institutions digitize items to preserve fragile materials and create more access points for patrons. They are different, but digitization is often a vital first step in digital preservation. Sometimes digitization and digital preservation are mistaken for the same thing. This potential has led to institutional digitization projects designed to improve access and the rapid growth of the digital preservation field. ĭigitization 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." Though analog data is typically more stable, digital data has the potential to be more easily shared and accessed and, in theory, can be propagated indefinitely without generation loss, provided it is migrated to new, stable formats as needed. In modern practice, the digitized data is in the form of binary numbers, which facilitates processing by digital computers and other operations, but digitizing simply means "the conversion of analog source material into a numerical format" the decimal or any other number system can be used instead. The result is called digital representation or, more specifically, a digital image, for the object, and digital form, for the signal. The result is the representation of an object, image, sound, document, or signal (usually an analog signal) obtained by generating a series of numbers that describe a discrete set of points or samples. Digitization is the process of converting information into a digital (i.e. ![]()
