Course Description

This course provides an in-depth discussion of computer networks. It includes a detailed discussion of the different Network Models. Concepts that have a direct effect on the efficiency of a network (e.g. collision and broadcast domains, topology) are also discussed. Concepts on different network technologies, distributed computation, networking, and communication software, and security issues are also discussed.

Course Objectives

Be familiar with the different Network Models; understand different network technologies; understand the effects of using different networking topologies; be updated with different advanced network technologies that can be used to connect different networks; be familiar with various hardware and software that can help protect the network; know the advantage of using a network management system.
