Digitalisation workbench

摘要

Information on its own is useless; it needs a context, and to be useful it needs to be translated into action. Modern storage and control systems can do wonderful things with sensor data - but that data needs to be in digital form. Here are some basics. Digitisation and digitalisation are two confusingly similar but separate terms which are not interchangeable. It is useful to know the difference: digitisation is the conversion of analogue signals into usable digital information (see box) - a purely technical procedure. It also encompasses the scanning of documents and images into electronic formats, such as PDF.
