DATA COMMUNICATIONS AND NETWORKING

Course Code: BTE 702 Credit Units: 03

Course Objective: The course provides a unified and fundamental view of the broad field of data communications networks.

Furthermore, the easy to understand and extremely relevant world of Computer Net working is introduced in a

top down Approach. Excellent online resources are available which are fun to use and learn and the student is

highly encouraged to look at them.
