iFrame - Computer Definition
(1) (I-frame) A keyframe in interframe compression. I-frames are fully intact video frames, from which subsequent frames are derived. See interframe coding.
(2) A digital video format from Apple. See Apple iFrame.
(3) (Inline FRAME) An HTML structure that allows another HTML document to be inserted into an HTML page. The iFrame is set up as a window frame of a specified size that scrolls along with the rest of the page, but the iFrame's content can itself be scrolled if it is larger than the iFrame window. Unlike the regular HTML frames function, which is used to divide the screen into multiple windows, the iFrame is typically used to insert an ad or small amount of text in the middle of a page. See frames, XFrames and HTML.
