Digitisation is the process of converting analogue information into a digital format. Analogue information is sometimes represented in a physical format which might have a higher likelihood of including errors. The digital data format is generally thought to be more stable and manageable.
Digitisation and digitalisation are not interchangeable terms. In the Energy White Paper, Powering our Net Zero Future (CP 337), published in December 2020 by HM Government digitalisation is defined as ‘…the integration of digital technologies into a process, organisation or system.’
Digitisation results in the creation of a digital representation of another object as data recorded in binary numeric form comprising ones and zeros (1, 0, also called 'bits') in various sequences to represent words and images. In this fashion, it is possible to create and store huge amounts of data.
Digital data can also be compressed from huge sizes down to more manageable packages. This allows large amounts of data to be transmitted with relative ease, and subsequently decompressed at the point of use.
