Course Description:
This course has been designed to introduce the concepts of basic computer communications and to make students aware of how networks (and specifically the Internet) functions today. The course offers students a variety of topics on data communication including the concept of layering, communication protocol stacks, and network devices and functions.

Course Learning Outcomes:
CLO:1 Describe and express the fundamental concepts of communication protocols and layered network architectures, especially information related to TCP/IP architecture.
CLO:2 Apply concepts of protocol layering to solve problems, and recognize different internetworking devices and their functions within a network.
CLO:3 Categorize network systems using the standard techniques and analyze features, services and operations of various network and transport layer protocols of communications task.
