USB

Universal Serial Bus.
A serial bus standard to connect devices to a host computer. USB was designed to allow many peripherals to be connected using a single standardized interface socket and to improve plug and play capabilities.
Everything today has a USB port and almost every electronic device can connect via USB.

My old computer had 1 usb port at the back. My new computer has 6 and my mouse, printer, iPod, keyboard, external hard drive, digital camera and refrigerator all connect to my computer via USB
