1. Scope and Objectives of the Course

1. The course aims at providing knowledge of topologies and small networks by following the top-down

approach from application to physical layer.

2. The course helps students to understand the layered approach of OSI reference model..

3. The course provides the base to prepare the students to study the distributed network concepts.

4. At the end of this course, students should be able to design, build and analyze simple networks using

the application-driven paradigm.
