Which of the following is used to measure the transmission rate of communication channels?
Correct answer: B. Bandwidth
- A. Asynchronous transmission
- B. Bandwidth
- C. Parallel transmission
- D. Frequency division multiplexing
Explanation
Bandwidth refers to the range of frequencies that a communication channel can carry. It's measured in Hertz (Hz) or its multiples (kilohertz kHz, megahertz MHz, gigahertz GHz). A higher bandwidth channel can transmit data faster because it can accommodate a wider range of frequencies.Here's an analogy: Imagine a highway with multiple lanes. A wider highway (more lanes) can handle more traffic flow (data) compared to a narrow highway (fewer lanes). Similarly, a channel with a higher bandwidth (more frequency range) can transmit data at a faster rate.
