Digital clocks are timekeeping devices that display the time using numbers instead of hands like traditional analog clocks. They typically show hours and minutes, and many also include seconds. Digital clocks can be powered by batteries or electricity and are often found in homes, offices, and public spaces. These clocks come in various designs and sizes, from small alarm clocks to large wall-mounted versions. Some digital clocks feature additional functions, such as alarms, timers, and backlighting for visibility in the dark. They are popular for their ease of reading and precise timekeeping, making them a common choice for many people.
