Growing up with aging tech

Question: What are the Windows A: and B: drives used for? It’s the type of thing that makes you feel like an old nerd. It reminded me of one of my teaching experiences late last year — one of the kids was looking at the title page of his planner (which contains all of the school’s contact information), and proceeded to ask me what a fax was. In a somewhat related note, both my father and brother say that faxing is still widely ingrained within the medical profession, and seemingly the legal profession as well.
