MTEL Technology and Engineering Test Answer Key

1. C: A binary is long strings of numbers used in computations. ASCII (American Standard Code for Information Interchange) is letters and punctuation signs combined with binary numbers. Hierarchy is the order to understanding and using information technology. The World Wide Web links information via bursts of binary data. Stored Program holds instructions and determines the next step in a process. Routing is the sequences of binary numbers moving through a connected network.

2. A: Graphic design is both the process of visual communication and the product created. Using typography, the visual arts and page layout, designers create an image that tells a story. The graphic designer must be creative, imaginative, have a keen eye for detail and balance, and understand the message and the audience.

3. B: Animation is the process of making drawings and inanimate objects appear to move. It began in the mid 1850s with the use of the zoetrope to simulate movement, graduated to stop-action photography as seen in the early cartoons of Walt Disney in the 1930s and has progressed to the computer-generated films currently being produced.

4. A: A simple explanation for the digital animation process: an image is displayed on the screen; it is quickly replaced with another image that is similar to the first but has shifted ever so slightly. This process is repeated as many times as necessary to complete the desired action. The images are then layered onto a virtual skeleton. Details are added and all related images are shown sequentially, creating the illusion of movement.

5. D: Linear multimedia moves without any control by the viewer. Non-linear multimedia has an interactive component that requires manipulation by the user. Multimedia presentations may be prerecorded or live action, seen in person or watched on a media player. They may be staged, projected on a screen or transmitted via an electromagnetic signal.
