2.4 VOCAB

Question 1

Part of a sound wave that is captured, measured, and assigned a numeric value during digital sound recording

Answer 1

Sample

Question 2

amount of memory used to store the numeric value of a sample. 8-bit sound uses eight bits, 16 uses 16, etc. Better the bit depth, better the sound

Answer 2

Bit depth

Question 3

number of individual samples taken each second during digital sound recording, most now are recorded at 44.1 kHz

Answer 3

Sampling Rate

Question 4

number of images or frames that are taken each second during digital video recording, common fps is 30

Answer 4

Frame Rate

Question 5

number of pixels in width and height of each frame in a digital video recording, better resolution= clearer image

Answer 5

Resolution

Question 6

amount of money computer uses to display colors in a digital image or video. 8-bit color images uses 1 byte, 24 bit uses 3 byte

Answer 6

Color Depth

Question 7

display on a computer monitor that is made of tiny red green and blue lights, combining to make a pixel. Will display different colors based on brightness of each light

Answer 7

RGB Display

Question 8

images stored by dividing a picture into rows of pixels and collecting color values of each pixel, in order by row

Answer 8

Raster Images

Question 9

images stored by mathematically describing the shapes in the image

Answer 9

Vector Images

Question 10

way of reducing file size, making them easier to store

Answer 10

File Compression

Question 11

compression algorithm, like GIF, PNG, PDF, and ZIP. doesn’t affect original data. When decompressed, exactly the same file as before compression

Answer 11

Lossless Compression

Question 12

compression algorithm, such as JPG MP3 and MP4. slightly alters data to make it easily storable. takes advantage of limited human senses, used for images videos, and audio. Cuts corners

Answer 12

Lossy Compression

Question 13

a common lossless compression algorithm that looks for repeated patterns of bits or bytes and records the pattern and then the number of times the pattern is repeated.

Answer 13

Run Length Encoding

Question 14

patch of pixels in a compressed image or video that have less visible detail than the rest of the image

Answer 14

Compression Artifact

Question 15

Kilobits of audio data processed each second

Answer 15

Bitrate

Question 16

Pieces of software that either compress or decomperss digital media

Answer 16

Video Codecs

Question 17

first step in designing a 3D model which provides the outline of the mode;, including only the vertices and lines without including surfaces textures or lighting

Answer 17

Wireframes

Question 18

advanced rendering method that is used to create incredibly realistic lighting effects for videogames and movies

Answer 18

Ray Tracing
