What are the elements of a data communication system except sender, receiver, medium, and voltage?
Correct answer: D. voltage
- A. Sender
- B. Receiver
- C. Medium
- D. voltage
Explanation
Voltage is not an element of a data communication system. While electrical signals are used to transmit data, the specific voltage level is not a key component of the system itself. Data communication systems can function with varying voltage levels depending on the transmission medium and protocols used. In essence, voltage is a property of the electrical signal used to carry data, not a fundamental element of the data communication system itself. The core elements are the sender, receiver, and medium, which facilitate the flow of information between devices.
