Input-Output Devices Flashcards
A hand-held scanner used to read the group of thick and thin lines (called a barcode) printed on various products. The barcode is linked to a database that contains information on the product.
Barcode reader
Allows access to a computer or device by identifying a person through one of their unique physical characteristics, such as finger or hand prints, retina or iris patterns, voice or facial recognition, etc.
Biometric device
A hand-held device used to record live-action video and audio. Originally, camcorders recorded onto magnetic tape. Some transitioned to small optical discs. Most now record onto flash memory cards or internal SSD. Camcorders usually come with additional software that you can use to edit the videos you record. (Also referred to as video cameras and video recorders.)
Camcorder
A hand-held device that records still images digitally instead of on photographic film. Digital cameras are limited by their maximum resolution and the number of colors they can represent.
Digital camera
Used to convert hand-drawn pictures into digital images that can be manipulated using computer software. You draw on the digitizer’s screen and what you draw is digitally rendered into the computer.
Digitizer
Used to digitize handwritten signatures, for example, to accept credit card signatures at the point of sale terminals. Some signature pads are designed to use a stylus while others are signed with a finger.
Signature pad
A hand-held device used to play video games. A gamepad can contain buttons, thumb sticks, joy pads, and triggers. It is held between both hands and controlled using your thumbs.
Gamepad
A device that controls the movement of the cursor on the screen. A joystick can also contain buttons. Typically used for gaming or graphics.
Joystick
A device used to input audio into a computer. Microphones can connect using the “mic” port on the computer sound card, to a USB port, or can be built-in. Microphones have many uses including: VoIP, voice recognition, gaming, online chat, dictation, and podcasts. Microphones are often built into laptop computers.
Microphone
An electronic sensor that detects physical motion in an environment. In computers and other electronic devices, motion sensors can be used for “waking up” the device, entering data using gestures, gaming input, start or stop video recording, and more.
Motion sensor
Captures printed photos and images for editing on a computer. Scanner types include hand held, flatbed, or automatic document feeder (ADF). Some scan in black and white only; others can do both black and white, and color.
Scanner
Smart cards are about the size of a credit card and used to store information. To access the information stored on the card you use a smart card reader. Smart card readers are configured to read specific types of cards. For example, some card readers are designed to read information off a magnetic strip; others read information off a microchip embedded on the card; some can do both. Smart cards can provide authentication and encryption, making them safe for financial transactions.
Smart card reader
Reads contactless payment cards or inventory tracking tags using near field communication technologies. Depending on the exact technology used the tag may need to be tapped against the reader, or simply be brought nearby.
NFC reader
A video camera that transmits live video over the Internet. Webcams are often built into the lid of laptop computers above the display screen.
Webcam
