What does USB stand for?

USB stands for Universal Serial Bus. This term refers to a standard that was developed to facilitate the connection, communication, and power supply between computers and various devices. The USB standard encompasses various versions that support different data transfer speeds and functionalities, allowing a wide range of peripherals—such as keyboards, mice, printers, and storage devices—to connect easily to computers.

The naming convention "Universal Serial Bus" highlights its broad applicability across numerous types of devices and its capability to transmit data serially (data is sent one bit at a time) rather than in parallel, which was common in earlier connection standards. This design allows for faster data transfer and simpler wiring, making USB a versatile and widely adopted interface in modern computing environments.
