Question

5. Describe the function of the following peripheral devices.
(a) Bluetooth adapter (b) Digital camera (c) Camcorder
(d) Graphic card​

Answer 1

Answer:

• a)A USB-based device that transmits and receives Bluetooth wireless signals. It plugs into the USB port to support Bluetooth mice, keyboards and other Bluetooth devices. Also called a "Bluetooth dongle." See dongle. Bluetooth adapters are tiny and barely protrude more than a half inch from the USB socket.

• b)A digital camera uses an electronic image sensor to create still photographs and record video. The optical system of a digital camera works like a film camera, in which a typical lens and diaphragm are used to adjust electronic image sensor lighting.

• c)More recent devices capable of recording video are camera phones and digital cameras primarily intended for still pictures; the term "camcorder" may be used to describe a portable, self-contained device, with video capture and recording its primary function, often having advanced functions over more common cameras.

• d)A Graphics Card is a piece of computer hardware that produces the image you see on a monitor. The Graphics Card is responsible for rendering an image to your monitor, it does this by converting data into a signal your monitor can understand.

Answer 2

Answer:

A)

Explanation:

A)A USB-based device that transmits and receives Bluetooth wireless signals. It plugs into the USB port to support Bluetooth mice, keyboards and other Bluetooth devices. Also called a "Bluetooth dongle." See dongle.

B)A digital camera is a hardware device that takes photographs and stores the image as data on a memory card. Unlike an analog camera, which exposes film chemicals to light, a digital camera uses digital optical components to register the intensity and color of light, and converts it into pixel data.

C)A camcorder (camera recorder) is a portable electronic recording device capable of recording live-motion video and audio for later playback. ... Professional videographers and filmmakers use camcorders to produce video segments and films for commercial sale.

D) Graphics cards allow computers to produce graphics and images more quickly. The video card connects to the motherboard and the monitor. ... This allows the card to accept information from the CPU (central processing unit) and send output to the monitor.
