A code is a system of sounds, symbols, or signs used by a group of people to communicate with one another. A speaker should choose a code that his audience understands to communicate with them. In other words, to pass information or message to the listeners, the speaker should select a language that they know.

Interference is anything that interrupts or causes obstruction, hindrance, or any phenomenon that makes communication impossible. Interference may not be destructive or deliberate sometimes, but at other times they cause distinct obstructions in communication. Hence, one must handle interference efficiently to have effective communication. Factors like human differences, cultural differences, social differences, and environmental differences
