Universal Serial Bus
A common interface used to connect peripherals, such as mice, keyboards, printers, and digital cameras to a computer.
Infrared
A communication technology that uses light waves to transmit information through the air.
Registered Jack 45 connector
A connector used to connect a computer to a wired network.
High-Definition Multimedia Interface Connector
A connector used to connect a computer to an HDMI monitor or TV.
Video Graphics Array
A connector, identified by its blue color and three rows of pins, that is used to connect older monitors to a computer.
Digital Visual Interface Connector
A connector, typically white with three rows of eight pins, designed to connect digital monitors to a computer.
Scanner
A device that can be connected to a computer or network that scans paper documents and converts them into digital files.
Peripheral
A device, usually external to a computer, that is plugged into a computer's communication port or is connected wirelessly. Common peripherals are keyboards, mice, monitors, speakers, and printers.
Touchscreen
A device, usually external to a computer, that is plugged into a computer's communication port or is connected wirelessly. Common peripherals are keyboards, mice, monitors, speakers, and printers.
Input
A keyboard allows you to send alphanumeric information to the system by pressing keys. The hardware within the mouse is able to keep track of its physical location on a hard surface.
Bluetooth
A short-range wireless communication technology used to connect peripherals such as wireless headphones, speakers, keyboards, mice, smart watches, printers, and game controllers to a computer, including smartphones.
Explain what each USB connector is designed for
A. USB allows you to connect a variety of external devices, including printers, digital cameras, external hard drives, and smartphones. B. FireWire functions in much the same manner as USB, allowing you to connect external devices, such as digital cameras, extra hard drives, and scanners to the computer system. C. The blue one is the line in connector, which can be used to connect an external audio source to the computer. The green one is the line out connector, which is used to connect speakers to the system. The pink one is the microphone jack, which is used to connect a microphone to the system. D. Computers also provide video connectors, which are used to connect an external monitor to the system. E. Most computers provide a connector that allows you to connect the system to a network.
Thunderbolt
An interface primarily used on Apple computers that typically connects a monitor to a computer and can also provide DC power.
FireWire
An uncommon interface used to connect peripherals such as digital cameras and external hard drives to a computer.
troubleshooting tip: Cables
Check all cables and connectors to make sure they're securely seated.
Output
Computers use output devices to display or send information.The mostly common type of output device is the monitor.
DVI
Digital Visual Interface
To record audio, a microphone can be connected to a desktop system using a FireWire connector, an audio jack, or a wireless connection.
False: USB
A scanner is used to create a hard copy of the information processed by the computer.
False: printer
External keyboards are optional for desktop systems.
False: required
The main functions of computer hardware are input, output, programming, and storage.
False; processing
Drivers
For some peripheral devices, you may need to load drivers before connecting the device for the first time.
HDMI
High Definition Multimedia Interface
Self Powered USB Devices
If a device can operate on this much power, it's considered a bus-powered device, which means the USB port provides 100 percent of its power.If a device needs more power than this, then it's considered a self-powered device and will typically have an external power adapter that plugs into a wall outlet.
troubleshooting tip: device with seperate power source
If the device requires a separate power source in order to operate, verify that it's plugged in.
troubleshooting tips: installing in a device on windows
If you're installing the device on Windows, open Device Manager and make sure the device is listed and enabled.
Troubleshooting tips: updated driver no longer works even after being updated
If you've recently updated the device driver and the device no longer works, roll back the driver to the previous version or revert the operating system to an earlier restore point.
Network
If your computer has access to a local network, either wired or wireless, you might install and configure peripherals to be accessed over the network.
