-A number that uniquely identifies each computer or device connected to the Internet. b) What are the four categories of output?
-Output is data that has been processed into a useful form called information. Four types of output are text, graphics, audio, and video. Text consists of characters (letters, numbers, punctuation marks, or any other symbol requiring one byte of computer storage space) that are used to create words, sentences, and paragraphs. Graphics are digital representations of nontext information such as drawings, charts, photographs, and animation (a series of still images in rapid sequence that gives the illusion of motion). Audiois music, speech, or any other sound. Video consists of images played back at speeds to provide the appearance of full motion. An output device is any computer component capable of conveying information to a user. c) Define i. resolution, ii. dot pitch, and iii. refresh rate. i) The number of horizontal and vertical pixels in a display device. ii) The distance in millimeters between pixels on a display device. Also called pixel pitch. text created with a smaller dot pitch is easier to read. Average dot pitch on LCD monitors should be .30 mm or lower. The lower the number, the sharper the image. iii)The refresh rate is the number of times in a second that a display hardware draws the data. This is distinct from the measure of frame rate in that the refresh rate includes the repeated drawing of identical frames, while frame rate measures how often a video source can feed an entire frame of new data to a display.
