The communication process involves a message, a sender, a channel, a receiver, and feedback.

• A message is a symbol or group of symbols that conveys meaning, such as a thought or an idea. For example, a letter contains words that are written symbols.  These convey a message to the reader.
• The sender is the person who creates the message and transmits it via a channel. In the previous example, the sender is the person who writes the letter.
• A channel is a means by which a message is sent, such as a letter, speaking in person or by telephones or electronically by email.
• The receiver is the person who receives the message, such as the recipient of a letter or an email message.
