What is essential for a device to function correctly in terms of transceiver signal strength?

Devices must have a strong physical connection
Devices must receive enough signal
Devices must always be powered on
Devices must have identical sensitivity levels

The correct answer is: Devices must receive enough signal

For a device to function correctly, it is crucial that it receives enough signal. Signal strength is vital in communication between devices, particularly in networking scenarios. If a device does not receive sufficient signal strength, it may lead to poor connectivity, data loss, or complete inability to communicate effectively with other devices on the network. This concept applies to both wired and wireless communications, where sufficient signal ensures data is transmitted and received accurately. While a strong physical connection, being powered on, and identical sensitivity levels may influence performance, they do not guarantee that a device will function correctly if the signal is inadequate. Signal strength directly impacts the ability to establish and maintain effective communication, making it the fundamental requirement for proper device functionality.
