Chapter 2.4 Vocab Flashcards
The part of a sound wave that is captured, measured, and assigned a numeric value during digital sound recording
Sample
Amount of memory used to store the numeric value of a sound sample
Bit Depth
The number of individual samples taken each second during digital sound recording. It’s measured in hertz
Sampling Rate
Number of images taken each second
Frame Rate
The number of pixels of each frame
Resolution
The amount of memory the computer uses to display colors in a digital image
Color Depth
A display on a computer monitor that is made up of sets of tiny red, green, and blue light
RGB Display
Images are stored by dividing a picture into rows of pixels and collecting the color values of each pixel
Raster Images
Images stored by mathematically describing the shapes in the image
Vector Images
A way of reducing the size of files, making them easier to store
File Compression
compression algorithm that doesn’t affect the original data
Lossless Compression
compression algorithm that slightly alters the data to make it easier to store
Lossy Compression
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
Run-Length Encoding
patch of pixels in a compressed image or video that have less visible detail than the rest of the image
Compression Artifact
Kilobits of audio data processed each second
Bitrate
