Lesson 11. Peripherals > Plug-and-Play Buses

Plug-and-Play Buses

The two most commonly used plug-and-play buses for connecting peripheral devices to Macintosh computers are Universal Serial Bus (USB) and FireWire. Bluetooth is less common, but is gaining popularity. Plug-and-play buses allow you to connect, use, and disconnect devices while the device and the computer are powered on (hot-swapping), without the need to install special drivers or software for the devices to function.

USB 1.1/2.0

Universal Serial Bus (USB) is a plug-and-play interface for external add-on devices such as audio players, joysticks, keyboards, phones, scanners, and printers. You can connect USB devices directly to your computer or to other USB devices. For example, you can connect your USB mouse to your USB keyboard, which is then connected to your computer. You can also purchase USB hubs that allow you connect several USB devices to a single port on your computer.
