- noun matching communications equipment that makes sure that power losses are kept to a minimum
- An electric circuit, network, or instrument that has four or more branches, or arms, each with a component such as a resistor or capacitor. It also has a current source and a null detector, and when such a bridge is balanced, its output is zero. A bridge allows for an unknown component replacing one of the branches to be accurately measured, as it can be compared to known values. Bridges may be utilized to determine unknown resistances, capacitances, inductances, frequencies, and so on. Its characteristic shape is that of a diamond. Also known as bridge circuit, or electric bridge.
- A device which connects networks or segments of networks at the data link layer, utilizing the same communications protocols. When connecting LANs, however, such bridges are protocol-independent. Also called network bridge.
