What is another common term for the device that links multiple videoconferencing sites into a single conference, often described as bridging different sites?

• A. Multi-point Control Unit
• B. Bridge
• C. Mobile Telehealth
• D. MPEG

Answer: (B)

In videoconferencing, connecting several sites into one shared conference is accomplished through bridging. The hardware that makes this possible is commonly called a Bridge or video bridge, because it literally links and coordinates streams from multiple endpoints so everyone participates in the same session.

Sometimes you’ll hear this device described as a Multi-point Control Unit (MCU), which is the more technical label for the same function. The everyday term, though, is Bridge, which is why it’s the best answer here.

The other options don’t describe the equipment used to connect sites: MPEG is a video compression standard, and Mobile Telehealth refers to a service area, not the hardware that links multiple locations.
