An RCA jack, also referred to as a phono connector or Cinch connector, is a type of electrical connector that is commonly used in the audio/video market. The name "RCA" derives from the Radio Corporation of America, which introduced the design by the early 1940s to allow mono phonograph players to be connected to amplifiers.

A gender changer is a hardware device placed between two cable connectors of the same type and gender. An example is a cable connector shell with either two female or two male connectors on it (male-to-male or female-to-female), used to correct the mismatches that result when interconnecting two devices or cables with the same gender of connector.

RJ11 is a physical interface often used for terminating telephone wires. It is probably the most familiar of the registered jacks, being used for single line POTS telephone jacks in most homes across the world.Cables sold as RJ11 are nearly always 6P4C (six position, four conductor), with four wires running to a central junction box. Two of its six possible contact positions connect tip and ring and the other two conductors are then unused. 6P2C and 6P6C can also be found in stores.
