One input device for a computer is a keyboard, a keyboard should use an interrupt-based i/o because when you are typing a keyboard you are creating a new change which the device needs to work through to make sure it does not miss any inputs from the keyboard whilst doing other tasks. An example of a situation where serial transmission may be better is when connecting to a very far away device such as a printer or modem in which while data does need to be transmitted, it is too far of a distance to be at all economical to use parallel transmission.
