the most popular technology for connecting peripherals.

USB ports are conveniently located on the front of the system unit for easy access. When you install a peripheral device, you are creating a connection for data to flow between the device and the computer. Within a computer, data travels from one component to another over circuits called a data bus. One part of the data bus runs between RAM and the microprocessor. Other parts of the data bus connect RAM to various storage and peripheral devices. The segment of the data bus that extends between RAM and peripheral devices is called the expansion bus. As data moves along the expansion bus, it can travel through expansion slots, cards, ports, and cables. An expansion slot is a long, narrow socket on the system board into which you can plug an expansion card. An expansion card is a small circuit board that gives a computer the capability to control a storage device, an input device, or an output device. Expansion cards are also called “expansion boards”, “controller cards”, or “adapters”. Expansion cards are built for only one type of slot. An expansion port is any connector that passes data in and out of a computer or peripheral device. Built in ports supplied with a computer usually include a mouse port, keyboard port, serial port, and USB ports. Most notebook computers are equipped with several USB ports.

Some devices require software, called a device driver, to set up communication between your computer and the device. The directions supplied with your peripheral device include instructions on how to install the device driver. Typically, you use the device driver disk or CD one time to get everything set up, and then you can put the disk away in a safe place.
