What is the purpose of an "Ending Sign" in a message?

The "Ending Sign" serves a specific role in message formatting and communication. It is used to denote the conclusion of a message. This is an important aspect in ensuring clarity and proper interpretation by the recipient. The use of an "Ending Sign" helps distinguish the end of the content, thereby preventing any potential confusion about whether the message is complete.

While some options may seem relevant, they don't align with the defined purpose of the "Ending Sign." The notion of it being called "Carriages" and represented as "NNNN" specifically addresses the standard terminology and notation used in communication protocols. This reinforces clarity in the structure of messages, enabling effective and accurate conveyance of information.
