Final Practice Exams 104 English Total Points: 50 Practice Exam Read the following passage, and then answer the questions: Terminals As central computers became faster and more powerful, it was possible to establish many remote display stations from which operators could all use the same computer to display information and enter data. Later, even small machines were equipped with a fairly large display screen and keyboard oriented towards use by a person with limited training, rather than by a highly skilled computer operator. For many interactions with computers a permanent record is unnecessary; therefore, output that is scanned once and then thrown away produces a lot of wasted paper. To solve this problem cathode ray tube(CRT) terminals can be used. These terminals are completely silent and frequently much faster than hard-copy terminals. CRT terminals are very useful interactive devices for use in offices and in other areas. These display terminals are diverse and of many colors. The original video output was single-color (black and white) uppercase, but in more highly developed devices, lower-case letters can be displayed, and some give options of blinking and dual-density characters. Certain screens can produce `negative' (dark)characters on a bright background or even make each character a different color, if so desired. The latter is an important feature in order to catch someone's attention when a value is abnormal. More of these sophisticated screens can generate continuous lines for graphic displays. The simplest of these are monochromatic and may have strictly limited graphic applications. They may use special characters strung together in ordr to form lines that look continuous, or they may be restricted regarding the number and the shape of curves that can be drawn at once. Multicolor pictorial graphics which are extremely useful in emphasizing contrast, have been used with good results in nuclear medicine, where differences in intensity would be too subtle if shades of only one color were used. A. Main Idea: Circle the main idea of the passages: (5 pts) 1. CRT terminals are interactive peripheral devices which allow users access to the computer even from remote stations. 2.
