composite video

A video signal in which all the image information (color, brightness, line, field, sync, etc.) are mixed together. Cross-color artifacts become apparent in composite video.

dynamic IP address

A dynamic IP address is an address that changes every time a user logs into their ISP (Internet service provider). This makes their address more secure, as it is harder for unauthorized users to access the address should they come across it via the Internet. It also allows a user to track down the source of an unwanted message.
