This course offers a general introduction to computer networks. It explores the structure, goals, services and problems of computer networks. The structure of computer communications is examined using the Open Systems Interconnection (OSI) seven layer protocol model. The purpose of each layer is discussed from both conceptual and practical aspects, and data communication standards are examined in terms of their layered structures. The distinction between circuit and packet switching is highlighted, and client server distance applications are discussed.
