SHORT ANSWER
1. How does resolution affect images displayed on a monitor? Resolution is the number of horizontal and vertical pixel in a display. Example: monitor has 1440 x 900, that’s mean resolution up to 1440 pixel per horizontal row and 900 pixel per vertical row. Pixel is a single point in an electronic image. so, a higher resolution uses a greater number of pixels and thus provides a smoother, sharper, and clearer image on your monitor.

How does resolution relate to the size of an LCD monitor or screen? Because in your monitor, there is native resolution which is use to setting optimal resolution and to gear LCD in specific resolution.

Infrared printing use infra red light waves.devices have to lines up the IrDA port on devices with IrDA port on the printer.

4.How does an ink-jet printer work?
– a small resistor heats the link, causing the ink to boil and form a vapor bubble

What is audio resolution, and what are three examples of audio resolutions? The number of bytes that represent sound in a given time, is stated as a bit rate such as 8-bit, 16-bit, or 24-bit.
examples: 8-bit = AM radio, 16-bit = optical disc-quality sound, 24-bit = high quality digital audio editing
