USB, or universal serial bus, was developed to be a an instant, no-hassle way to connect a new digital joystick, a scanner, a set of digital speakers, external storage devices, a digital camera, or a PC telephone to personal computers.

A feature known as "hot-swapping", you don't even need to shut down and restart your PC to attach or remove a peripheral. USB also lets you connect many peripherals at one time. Many USB PCs come with two USB ports. And USB hubs have additional ports that let you "daisy-chain" multiple peripherals (devices) together. USB even delivers enough power to run small devices.

Almost all desktop and laptop computers today have either USB 1.1 or 2.0 ports.
