a device receives the binary code “101”. what does this sequence of pulses mean? the signal is on, then off, then on again. the signal is getting stronger, then weaker, then stronger. the signal is off, then on, then off again. the signal is continuous for three seconds

Explanation:

In binary signaling, 1 represents an "on" (active) signal and 0 represents an "off" (inactive) signal. For the sequence "101", the first digit 1 is on, the second digit 0 is off, and the third digit 1 is on again.

A. The signal is on, then off, then on again.
