RCA jacks are cylindrical connectors typically colored red, white, and yellow. The red and white jacks are used for stereo audio connections (red for right channel and white for left), while the yellow jack is used for composite video. They have a metal tip and a plastic sleeve that helps secure the connection in place. RCA jacks are commonly found on televisions, audio equipment, and various multimedia devices.
