In some cases analog connections can be subject to distortion which doesn't happen in digital. But the main difference between digital and analog is that they are two methods of sending a signal. The Analog method merely converts the signal to audio or video at the receiver's end, which may carry distortions or interference it might've picked up along the way. However, in digital, the signal received is interpreted as data which is used by a processor to create audio or video from that data locally. In other words, in digital systems, the audio or video signal is actually created at the receiver's end. Therefore, since only the data received is interpreted it doesn't recreate interference or distortion the signal may have picked up along the way. In the transmitter's or sender's end only the information needed to create the audio or video is transmitted, but not the video or audio itself.
