Data Communication Systems and Networks

At the end of this course, the students should be able to: 1. outline the basic concepts of data communications and networking; 2. describe the purpose of network layered models, OSI and the Internet Model using TCP/IP protocols; 3. illustrate noise, attenuation, and distortion and state their impact on data digital transmission; 4. demonstrate Flow and Congestion control; and 5. describe the use of network components like Bridges, Switches, and Routers.
