USB stands for Universal Serial Bus. It is an industry standard developed to enable digital data transmission and power delivery between computers (hosts) and peripheral devices such as keyboards, mice, printers, and storage devices. USB was introduced in 1996 to standardize and simplify the connection of various peripherals, replacing multiple earlier types of ports like serial and parallel ports. The "Universal" part signifies its wide acceptance and standardization globally, "Serial" refers to the method of data transmission one bit at a time, and "Bus" denotes a communication system that transfers data between components inside or between computers
