What does USB stand for?
USB stands for Universal Serial Bus. It is an industry standard that defines the cables, connectors, and communication protocols used in a bus for connection, communication, and power supply between computers and electronic devices. The term ‘universal’ in USB signifies its ability to connect a wide variety of devices to a computer.
The term ‘serial’ in USB refers to the fact that data is transmitted one bit at a time over a single wire. This is in contrast to parallel buses, which transmit data in parallel over multiple wires. The term ‘bus’ in USB refers to the fact that multiple devices can be connected to the same bus, allowing them to communicate with each other.
