Answer:
A clock is a device used to measure, keep, and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units: the day, the lunar month, and the year. Devices operating on several physical processes have been used over the millennia.Timepieces allowed us to measure time in accurate, uniform ways. And, once we had that ability, we began to look at the way we live and work quite differently. ... It is the mechanical clock that made possible, for better or worse, a civilization attentive to the passage of time, hence to productivity and performance.”The use of a (signal) clock in digital circuits allows all operations in the circuit or system to be synchronized. The clock might contribute to the change(s) of flip-flop states. ... Circuits using a clock signal for synchronization may become active at either the rising edge or falling edge of the clock signal.A clock or watch is called "analog" when it has moving hands and (usually) hours marked from 1 to 12 to show you the time. Some have Roman Numerals (I, II, III, etc) instead, or no numbers at all! In other words: not a digital clock.The first mechanical clocks, employing the verge escapement mechanism with a foliot or balance wheel timekeeper, were invented in Europe at around the start of the 14th century, and became the standard timekeeping device until the pendulum clock was invented in 1656.
