Communication:-

Communication is the exchange of information, thoughts, or ideas between individuals or groups through speaking, writing, or using some other medium. It involves encoding and transmitting messages, and decoding and interpreting messages received, with the goal of effectively conveying meaning. Communication can occur between people, animals, or machines, and is a vital aspect of human interaction and relationships.
