This document discusses different types of organizational communication. It defines communication as the exchange of information between individuals or organizations. There are three main forms of organizational communication: internal operational communication within a company, external operational communication with outside groups, and personal communication between employees. The frequency and forms of communication depend on factors like the business nature, organization structure, and employee characteristics. Effective communication networks are important for companies and can be likened to circulatory systems, with formal channels as the main arteries and informal grapevines as secondary veins.
