Digital clocks
A digital clock displays time numerically using electronic components, typically showing hours and minutes, sometimes seconds. It functions by counting the cycles of an internal oscillator, often a crystal or resistor-capacitor circuit, which maintains precise timing. This signal is processed by a clock circuit that updates the display at regular intervals. Digital clocks can be powered by batteries or electricity and often include features such as alarms or date displays. They provide a clear, easy-to-read format, making it simple to tell time accurately at a glance without interpreting traditional clock hands.
