Digitization is the move from analog to digital.Not so long ago, businesses kept records on paper. Whether handwritten in ledgers or typed into documents, business data was analog. If you wanted to gather or share information, you dealt with physical documents — papers and binders, xeroxes, and faxes. Then computers went mainstream, and most businesses started converting all of those ink-on-paper records to digital computer files. This is called digitisation:

The process of converting information from analog to digital. Finding and sharing information became much easier once it had been digitised, but the ways in which businesses used their new digital records largely mimicked the old analog methods. Computer operating systems were even designed around icons of file folders to feel familiar and less intimidating to new users. Digital data was exponentially more efficient for businesses than analog had been, but business systems and processes were still largely designed around analog-era ideas about how to find, share, and use information.
