This presentation discusses types of communication. It defines communication and identifies five main types: downward, upward, horizontal, diagonal, and vertical communication. Downward communication involves information flowing from higher to lower levels in an organization. Upward communication is the reverse, with information moving from lower to higher levels. Horizontal communication occurs across same levels, while diagonal communication involves different departments. Vertical communication encompasses both upward and downward flows through an organization's hierarchy. Examples of each type are provided.
