Non-verbal communication

Language differences –

Inability to converse in a language that is known by both the sender and receiver is the greatest barrier to effective communication. When a person uses inappropriate words while conversing or writing, it could lead to misunderstanding between the sender and a receiver. . On the Internet, for example, the lingua franca is badly written and poorly understood English. Some people use it as their native language; other learned some of it from various sources. In any case, whatever you say will be interpreted in a myriad of ways, whether you use idiomatic English or not.
