What is the difference between internal and external communication in a organization?

Internal communication involves the communication that exists within a company and can take many forms. Key to the success of an organisation is communication from within. In order to effectively engage in two-way symmetrical communication, (the goal of public relations practitioners), communication is essential internally.

External communication covers how a provider interacts with those outside their own organisation. This may be with the public, employers, community organisations, local authorities, job centers, careers offices, funding bodies, specialist agencies and other training providers.
