 Analog
clocks usually are clocks that have hands. An analog clock may be
mechanical, or it may have a quartz movement. An analog has a clock
face with a fixed number dials and also moving hands to tell the
time. An analog clock is a 12 hour clock. It has a circular scale
of 12 hours which is also a circular scale of 60 minutes and also
of 60 seconds. The first analog clock is actually the sundial -
a sundial tracks the sun continuously and registers the time by
the shadow the sun and the gnomon create on the sundial.
A digital clock, on the other hand, does not generally use hands
to show the time like an analog clock does. Instead, a digital clock
uses number for input, processing, transmission, storage, or display
- an analog clock uses a continuous spectrum of valves.
The main difference between analog clocks and digital clocks is
that analog clocks move in a continuous motion. Digital clocks,
on the other hand, have small fluctuations.
There are, though, analog clocks with digital displays. An analog
clock with a digital display does not have hands that show the time.
Rather, such an analog clock has numbers that change and show the
time. But such an analog clock still keeps time in an analog fashion.
The electric motor of an analog clock with a digital display turns
two wheels continuously. One wheel goes at a rate of 1 revolution
per hour. The other wheel is at a rate of 1 revolution per 24 hours.
These wheels move continuously, not in steps like a digital clock.
The wheels of the clock have parts with numbers printed on them.
Every minute the wheels flip over a new number.
There are also analog clocks (ones with hands) that are, in fact,
digital clocks. This is so, because the hands do not move in the
smooth continuous motion that is central to the definition of analog.
Rather, such analog clocks (that are actually digital clocks) have
hands that move in small steps (every second, minute, or half seconds).
Both analog clocks and digital clocks can keep the time equally
as well, the difference is just in the motions.
