Latch is a term that can refer to a device used to secure doors, gates, or other openings. It typically consists of a metal or plastic mechanism that can be easily opened or closed, providing a simple way to keep things safe. Latches come in various designs, including sliding, spring-loaded, and hook types, and are commonly found in homes, vehicles, and outdoor equipment. In technology, "Latch" can also refer to a type of electronic circuit used in digital systems. It stores a binary state (0 or 1) and maintains that state until it is changed by an input signal. Latches are fundamental components in devices like computers and smartphones, playing a crucial role in memory storage and data processing.
