What is Online
Online means when a machine is in running state and is connected with another device....

In the same way, devices like, scanners, video Cameras, audio Interfaces and other things can be asked to be online when they are running and connected together with computer system.
But, the term "online" actually means being connected to the Internet. This connection is available on every mode, either it's a phone line, or a dial-up or DSL modem, a cable line or via cable modem, or just a wireless connection.
