Internal communication occurs within the organisation while external communication is between an
organisation and other organisations, customers or individuals who are external to the particular
organisation. Internal communication networks are patterns of relationships through which
information flows in an organization. Stohl (1995) describes communication networks as capturing
“the tapestry of relationships—the complex web of affiliations among individuals and organizations
as they are woven through the collaborative threads of communication” . Communication
networks emerge in organizations based on formal and informal communication
External communication must pass through the registry section which keeps record of such
communication. It involves communication with individuals and organisations outside our
organisation.
