[[ASCII]] is a convention by which specific patterns of 8 bits -- which we usually represent as numbers, just because bit-patterns are not very human-compatible -- are understood to refer to specific characters on the keyboard (including a few "special" characters like carriage-return and tab, which are arguably formatting operations).

	(Aside: so, like, historically, sometimes the top bit of the 8 was needed for parity-checking in serial communications, so traditional ASCII actually only uses 7 bits -- 128 possible characters. [[MS DOS]] used all 8 bits because IBM PC displays weren't serial terminals, which had been the case for pretty much everything before that, but basically internal electronics that the computer could talk to directly -- so no need to worry about parity-checking for comms. MS DOS therefore defined another 128 characters which allowed text-mode DOS to do things like use text to draw lines, and also have accents on some Roman characters and a few Greek characters and other miscellany. You don't actually need to know this in order to understand the rest, but I often find it helpful to explain how things got the way they are.)
