What is the difference between TE and TR?

• A. TE serves a limited number of users
• B. TE transmits data faster
• C. TE uses fiber optic
• D. TR is wireless

Answer: (A)

The key idea is what each term refers to in a network: Terminal Equipment versus Transmission Resource. Terminal Equipment is the gear at the user’s end that terminates the connection—things like PCs, phones, or a user’s router. This equipment is designed to serve a limited number of users or devices at a single site. Transmission Resource, on the other hand, is the network portion that carries signals between equipment and can support multiple TE connections along a shared path. It’s the broader transmission path, not the edge devices.

So TE serves a limited number of users because it represents the end-user devices and interfaces at a specific location, whereas TR represents the network’s shared transmission path that can connect many TE devices. The other statements aren’t defining differences between TE and TR: the speed of TE isn’t fixed by it being TE, the medium isn’t inherently fixed to TE, and TR isn’t inherently wireless in this context.
