CLOCK

A clock represents an apparatus employed in indicating, measuring, and synchronizing time. Etymologically, the term "clock" stems from the Celtic words 'clagan' and 'clocca,' signifying 'bell.' Traditionally, a time-measuring device devoid of audible mechanisms is called a timepiece. In contemporary language, a clock encompasses any gadget designed to gauge and display time. Watches or portable timepieces are often distinguished from clocks. As one of humanity's earliest inventions, the clock fulfills the necessity for consistently gauging intervals shorter than natural units: day, lunar month, and year. Throughout history, devices relying on diverse physical principles have been employed. The evolution of clock technology continues to this day.
