Techopedia Explains Capture

Capture refers to taking analog data and converting it into
digital. One of the most obvious uses is video capture. A video capture card
might take a video signal coming over the air or from a VCR and convert it into
a digital format, such as MP4 for later viewing and editing. Similarly, audio
capture refers to digitally recording analog audio. A screen capture refers to
taking a picture of a computer screen, to show a computer program in action or
to show off one’s desktop customizations.
