This document discusses communication networks in business settings. It identifies 7 types of networks: fan, circle, chain, wheel, Y, daisy, and all-channel. Each network type has a different structure and flow of communication. For example, a wheel network is centralized with a clear leader at the center, while an all-channel network is decentralized and allows everyone to interact with everyone else. The networks can facilitate coordination, information sharing, and directing activities within an organization.
