Universal Serial Bus (USB)

The Universal Serial Bus (USB) is an industry-standard interface that establishes communication between devices and a host controller (usually a personal computer). USB is used to connect peripherals such as keyboards, mice, printers, external storage devices, and smartphones. It allows for data transfer and power supply between devices. USB has evolved over time, with versions like USB 2.0, USB 3.0, and USB-C offering increased data transfer speeds and improved power delivery.
