The term "word" in computing is referring to a space of type. When typing information on a keyboard each stroke is counted. Every time five strokes are made, the computer counts it as one word.

The traditional computer is a Desktop PC, with a monitor, keyboard and mouse. Also, some sort of internet connection.
