Which of the following is NOT a reason for a digital communicator to fail in establishing a connection?

1. Network connectivity

2. Signal interruption

3. Incorrect programming

4. Power failure

The correct answer is: Network connectivity

A digital communicator relies on various factors to successfully establish a connection, and network connectivity is a fundamental aspect of its operation. While the other options represent common issues that can disrupt communication—such as signal interruption, which can be caused by obstacles or interference; incorrect programming, which may prevent the proper transmission of data; and power failure, which stops the device from functioning altogether—network connectivity is a prerequisite for these devices to work effectively. If the network is functioning properly, the digital communicator should be able to establish a connection unless hindered by other issues.
