C
Input device used for games playing and flight simulators.
D
the ability to work in different locations while storing data on the hard drive, wide variety of models available, integrated keyboard > no desk required
Explanation: 

Detailed explanation-1: -Noisy – Dot matrix printers are noisier than other types of printers, they can be disruptive to quiet environments. Prone to jamming – Because dot matrix printers use a ribbon to transfer ink to the paper, they are more prone to jamming if the ribbon is not loaded or maintained properly.

Detailed explanation-2: -The density of barcodes is low and color printing is limited. Print Speed – Dot matrix printers are very slow compared to laser. Noise Level – With the pins striking the ribbon to the paper, the dot matrix printers when in use are very loud. Print Head Sensitive-The pins can get bent easily damaging the print head.

Detailed explanation-3: -Dot matrix printers create noise when the pins or typeface strike the ribbon to the paper, and sound-damping enclosures may have to be used in quiet environments. They can only print lower-resolution graphics, with limited color performance, limited quality, and lower speeds compared to non-impact printers.

Detailed explanation-4: -Answer: true, dot matrix is less expensive but very noisy.

Detailed explanation-5: -Whilst all printers will make a noise to some extent, the crown for the noisiest type of printer must go to the dot matrix printer.
