Communication codes are systems of signals or symbols used to convey messages. These codes can include verbal language, body language, gestures, and even written symbols. They help individuals understand each other by providing a shared framework for interpreting information. Different cultures and groups may have their own unique communication codes. For example, sign language is a code used by the deaf community, while emojis are often used in digital communication to express emotions. Understanding these codes is essential for effective communication and can help prevent misunderstandings.
