Cards in this deck (17)

1—peri[heral
computer peripheral, input-output device, or input/output device, any of various devices (including sensors) used to enter information and instructions into a computer for storage or processing and to deliver the processed data
2—touchscreen
A touchscreen or touch screen is the assembly of both an input and output device.
3—inkjet printer
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates.
4—laserjet printer
A laser printer is a popular type of personal computer printer that uses a non-impact (keys don't strike the paper), photocopier technology. When a document is sent to the printer, a laser beam "draws" the document on a selenium-coated drum using electrical charges. ... The toner adheres to the charged image on the drum.
5—scanner
An image scanner—often abbreviated to just scanner—is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image.
6—Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and protocols for connection, communication and power supply (interfacing) between computers, peripherals and other computers.
7—FireWire, also called IEEE 1394 or i. LINK, high-speed computer data-transfer interface that was used to connect personal computers, audio and video devices, and other professional and consumer electronics. ... Devices on a FireWire network could be connected and disconnected without cycling power.
8—Video Graphics Array is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, which became ubiquitous in the PC industry within three years.
9—Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor.
10—High-Definition Multimedia Interface is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source
11—Registered jack-45 (RJ45) refers to a cable termination specification that specifies physical male and female connectors and the pin assignments of wires-in telephone cables and other networks that use RJ45 connections.
12—Thunderbolt is the brand name of a hardware interface for the connection of external peripherals to a computer. It has been developed by Intel, in collaboration with Apple. It was initially marketed under the name Light Peak, and first sold as part of an end-user product on 24 February 2011.
13—Infrared (IR) is a wireless mobile technology used for device communication over short ranges. IR communication has major limitations because it requires line-of-sight, has a short transmission range and is unable to penetrate walls. ... Thus, data transmitted between IrDA devices is normally unencrypted.
14—Bluetooth is a wireless technology that allows the exchange of data between different devices. While Bluetooth uses wavelength to transmit information, it generally only works within a short distance for the devices to stay connected.
15—A camera lens is the part of a camera that directs light to the film or, in a digital camera, to a computer chip that can sense the light. ... For example, a telephoto lens can take a picture of something far away. A wide-angle lens is the opposite.
16—Photosensitive material
A material that changes its chemical composition when exposed to electromagnetic radiation. Note: Examples of photosensitive materials are (a) the material on the surface of an optical disk prior to recording data on it and (b) the coating on unexposed photofilm used in cameras.
17—camera shutter
shutter, in photography, device through which the lens aperture of a camera is opened to admit light and thus expose the film (or the electronic image sensor of a digital camera).
