A 19-inch rack is a standardized framework used for housing electronic equipment, particularly in data centers, server rooms, and telecommunications environments. The term "19-inch" refers to the width of the rack's internal mounting space, which is 19 inches (approximately 48.26 cm) between the internal mounting rails. This standard allows equipment such as servers, networking devices, and other hardware to be easily installed and removed.
