The story behind the word. The term 'online' is a relatively modern compound, emerging in the mid-20th century. It combines the preposition 'on' with the noun 'line', referring to a communication line or circuit. Initially, it described equipment that was directly connected to and controlled by a computer. With the rise of the internet, its meaning expanded to encompass anything accessible via a computer network.
