NOTE

DIGITALIZATION OF DATA

Digitalization is the process of converting information into digital format. This information may represent an object, image, sound, document or a signal (usually an analog signal) organized into discrete set of its points or samples. This is the binary data that computers and many devices with computing capacity (such as digital camera and digital hearing aids) can process.

Digitalization can also be defined as the integration of digital technologies into everyday life.

BENEFITS OF DIGITALIZATION

  1. Long term preservation of documents
