Morphology

extension = extend (semi-transparent) = extend + sion

The link to 'extend' is clear because these items add or lengthen function, but the specific technical senses such as phone or file extension are conventionalized.

Etymology

Extension comes from the Latin parts ex- 'out' and tendere 'to stretch', which gives the image of an extra part reaching out from the main thing. So a phone line, file add-on, or device that is added to a system is called an extension.
