section 2.4 vocab Flashcards
The part of a sound wave that is captured, measured, and assigned a numeric value during digital sound recording.
sample
The amount of memory used to store the numeric value of a sound sample during digital sound recording. > the better the bit depth, the better the sound.
bit depth
(measured in hertz) the number of individual samples taken each second during digital sound recording. > the higher the sampling rate, the better the recording
sampling rate
The number of images, or frames, that are taken each second during digital video recording
frame rate
The number of pixels in the width and height of each frame in a digital video recording.
resolution
The amount of memory the computer uses to display colors in a digital image or a digital video.
color depth
A display on a computer monitor that is made up of sets of tiny red, green, and blue light that make up a pixel
RGB display
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
A compression algorithm that doesn’t affect the original data.
lossless compression
A compression algorithm that slightly alters the data to make it easier to store. used in images, audio files, videos
lossy compression
algorithm that looks for repeated patterns of bits or bytes records it and numbers the number of times repeated
Run-Length Encoding
A 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
Video Codecspeices of software that either compress or decompress digital media
Video Codecs
