The Bridge Between Two Plugs

Written by Studio AM.

A cable has one kind of plug, but a screen has another port. An adapter can form a bridge between them. One end fits the cable. The other end fits the screen.

Matching shapes is only the first step. The devices must also send a signal the other side can understand. Some adapters simply connect matching wires in new positions. Others contain tiny circuits that translate one signal into another.

An adapter cannot create every missing ability. A phone may not send video through its port at all. No plug shape can add that feature by itself. Before choosing an adapter, a user should check both devices and the kind of signal needed. Both the connection and the signal need to be supported.
