Overview over the fundamentals of data communication (speech, audio, video and data). The lower layers of both OSI and Internet are discussed. Global and local functionalities of the Internet and Intranets shall be made transparent. Special focus is on fundamentals and principles, as well as the key insight that networks are not exclusively built on IP-based technology.
