Techopedia Explains Device

A device can be embedded in a computer or be connected outside of it, but all devices can be separately installed or replaced. That said, devices in notebook and other portable computers tend to me more integrated. There are contradictions about a device’s scope; whereas some believe the computer’s components, others say the computer is a device in and of itself. Moreover, with the advent of cloud computing and virtualization, virtual machines and other related instances are also considered devices.
