Keyboard buffers are decidedly not on the physical keyboard. The keyboard might have a very small one, but the IRQ is triggered on every input.

The buffer in question is, for a tty, a driver-level buffer that holds on to the data until something reads it. If a command doesn't read it (which things like apt-get update don't) then it'll get read as the next command.

Of course, most terminals these days are ptys accessed via emulators, so the buffer is actually part of the emulator, but the same idea applies.

For some reason my brain still finds it important to remember that the BIOS keyboard buffer is 15 bytes by default, but that you could load tiny little devices drivers in CONFIG.SYS in MS-DOS to make it a whole 31 bytes.
