The amount of memory used to store the numeric value of a sound sample during digital sound recording. 8-bit sound uses eight bits (or one byte) to store the value of each sample. 16-bit sound uses two bytes per sample. Generally speaking, the better the bit depth, the better the sound.

(a)  

The number of individual samples taken each second during digital sound recording. Measured in Hertz, the higher the sampling rate, the better the recording. Most modern sound recordings are made at 44.1 kHz.

(a)  

The number of images, or frames, that are taken each second during digital video recording. Most digital videos have a frame rate of about 30 frames per second.

(a)  

The number of pixels in the width and height of each frame in a digital video recording. The higher the resolution, the clearer the image will be.

(a)  

The amount of memory the computer uses to display colors in a digital image or a digital video. 8-bit color images use one byte of data for each pixel. 24-bit color uses three bytes for each pixel.
