What is the difference between an analog clock and a digital clock?
The difference between analog and digital technologies is that in analog technology, information is converted into varying amplitude electric pulses. In digital technology, information is translated into binary format (zero or one), with each bit representing two distinct amplitudes. Audio signals, like images, can have limited bandwidth when recorded digitally. The bandwidth is fixed once a digital recording is made. An analog recording is thought to be limitless. As a result, it can progress to higher and higher resolutions without losing its original quality. An analog clock with gears and springs may be more accurate than a digital clock in measuring elapsed time; even better if it has a sweeping second hand that displays the time.
