(2) (Universal Serial Bus) USB is a hardware interface for up to 127 peripherals that is governed by the USB Implementers Forum (see USB-IF). USB is used to attach keyboards, mice, printers, external storage and mobile devices to the computer. It is also used for charging a wide variety of portable products (see USB power). After debuting in 1997, USB soon replaced the earlier serial port, parallel port and Apple Desktop Bus.
Hot Swappable Drives
USB devices can be plugged and unplugged while the computer is on. This feature, combined with easy-to-reach ports on every computer, gave rise to the ubiquitous USB drive for transport (a manual "eject" is however required). See USB drive, USB device class, USB OTG, USB switch and USB toy.

| Host sockets are Type A, and peripherals use B, Micro-B, Mini-B, USB-C and Lightning. In time, USB-C is expected to replace A, as well as every other USB connector. Today, some laptops have only USB-C ports, while all other computers have Type A. See USB Type C, USB hub, Mini USB, Micro USB and Lightning connector. |
