DI unit. A professional passive DI box. It is passive because it does not need external power to operate. DI boxes which require a power source (batteries or phantom power) are called active DI boxes. A DI unit (direct input or direct inject) is an electronic device typically used in recording studios and in sound reinforcement systems to ...
A passive optical network (PON) is a fiber-optic telecommunications technology for delivering broadband network access to end-customers. Its architecture implements a point-to-multipoint topology in which a single optical fiber serves multiple endpoints by using unpowered (passive) fiber-optic splitters to divide the fiber bandwidth among the ...
An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions ...

Difference Between Passive Range of Motion and Active Range of Motion. Range of motion (ROM) refers to how far you can move or stretch a part of your body, such as a joint or a muscle. It’s ...
In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits. Two terminals constitute a port if the currents applied to them satisfy the essential requirement known as the port condition: the current entering ...
