Final answer:
Formal communication channels follow the chain of command within an organization, strictly adhering to the hierarchy of authority. Messages are communicated systematically between different levels of the organizational structure, from the top executives to the entry-level employees.
Step-by-step explanation:
Communication channels that follow the chain of command within an organization are referred to as formal communication channels.
These channels adhere to the hierarchy of authority, where messages are passed through levels of organizational structure, typically from superiors to subordinates, and vice versa. For instance, within a corporation like Walmart, a shift manager would receive directives from the store manager who, in turn, is guided by the regional manager, ultimately connecting to the CEO and the board members. Such a system ensures that information flows systematically in alignment with the established corporate governance structure.
