RJ11 stands for which of the following?

Explanation:
The naming uses a standard that assigns a number to each type of modular jack. RJ stands for Registered Jack, and the number following it identifies the specific jack type. So RJ11 is the Registered Jack 11 designation used for common residential phone lines. The word “Function” isn’t part of the official name, so “Registered Jack Function 11” isn’t the standard wording. In short, RJ11 = Registered Jack 11, typically a 6P2C (or 6P4C) connector for telephone service, while other RJ numbers (like RJ45) refer to different connector types used for other networks.
