Exam 8: Digital Media

-With vector graphics,like the one found in the accompanying figure,objects may be layered over other objects.

Anita fancies herself to be an artist on the computer. She has drawn a stylized image of the Parthenon using a series of long and rectangular objects for the columns, a triangular object for the roof, and a circular object for the sun. She layered the objects so that the roof object is layered in front of the columns and sun. She likes having a great deal of flexibility in arranging and editing image elements. -In addition to her computer,what other tool might Anita use to create vector graphics?

-You can use a scanner,like the one in the accompanying figure,to convert a printed image into a bitmap graphic.

The ____ format offers very good sound quality based on MPEG-4.

You plan to create a cartoon-like image of a computer to be used in a flyer for your school's computer lab.What type of graphic would you most likely use?

____________________ works by superimposing a grid over a vector image and determining the color for each pixel.

Today's ____ editing simply requires a computer hard disk and video editing software.

MATCHING Identify the letter of the choice that best matches the phrase or definition. -An undesirable "bitmappy" appearance

A vector graphic can quite easily be converted into a bitmap graphic through a process called ____.

-A scanner,like the one featured in the accompanying figure,creates a vector graphic.

Nancy has several types of video media originating from a variety of devices, including an analog video camera, a DVR (digital video recorder), and a TV. She also has video-editing software installed on her computer. -Nancy is using codec software to reduce the size of some of her video files by allowing her to specify a compression ratio or bitrate.If she is very concerned with minimizing the size of her video files,she could ____.

Cameras designed for still photography cannot capture video.

____________________ sound is an artificially created sound,of which MIDI music is an example.

Using a computer's infrared port to beam photo data from a camera,which eliminates the need for a cable,is much faster than using FireWire or USB._________________________

The color of each dot in a bitmap graphic is stored as a(n)binary number._________________________

MATCHING Identify the letter of the choice that best matches the phrase or definition. -The superimposition of a grid over a vector image,followed by the determining of the color for each pixel

____ refers to the process of selecting part of an image.

You have just decreased the number of pixels,resolution,and file size of your graphic by selecting a portion of the image.What have you done to your graphic?

Each ____ uses a unique compression algorithm that allows the user to specify the compression ratio and/or bitrate used when compressing video.

-In the accompanying figure,the bitmap image on the left was enlarged to create the image on the right by a process called pixel recalibration._________________________
