A digital clock is a type of clock that displays time in a digital format. This particular digital clock is of the 24-hour format, which means it can display time up to 24 hours (midnight). The clock is built using sequential components, which are electronic devices that can store information based on their current input and previous inputs. Flip-flops and logic gates are two types of sequential components. Flip-flops are used to store binary information, while logic gates are used to perform logical operations. Together, these components are used to create the digital display of the clock.
