This course provides the student with terminology and concepts related to data communications. Modes of data transmission and transmission media are discussed. Emphasis is placed on the integration of electronic principles with systems analysis and design for computer networks. The role of telecommunications in systems design for networking and distributed processing is presented, along with the architecture of data communication systems ranging from local area networks to international wide area networks. Also discussed are common data communication error detection and correction techniques, available communications software, common carrier services, and prevailing relative costs for those services.
