British spelling: converted into digital form that computers can read and process.
From 'digit' (Latin digitus, finger) + '-ise' (British suffix for making something). The term emerged in the 1960s as computing technology allowed physical information to be converted into numerical data.
The British vs. American spelling difference (-ised vs. -ized) reflects how English split into regional variants—but both versions are fighting hard: digitised documents now outnumber their printed originals by billions!
