Communication involves the sharing of ideas, experiences, knowledge, and feelings through symbolic messages. There are various types of communication including downwards, upwards, and lateral communication. Effective communication requires the message to be clear, concise, accurate, relevant, timely, meaningful, and applicable to the situation. Barriers to communication can include language, values, beliefs, gender, economic status, education, physical barriers, attitudes, timing, understanding of the message, and trust. New communication technologies provide immediate access to information and people but also require strategies like ensuring feedback, completeness of messages, and disconnecting regularly to balance their effects.
