Second Semester: 2012-2013 Course Handout: Part-II

Date: 01/01/2013

In addition to part-I (General handout for all courses appended to the timetable) this portion gives further specific details regarding the course: Course No. : CS C461 / IS C 461 Course Title: Computer Networks Instructor-in-Charge: RAHUL BANERJEE 1. Objective and Scope of the Course: This introductory course on Computer Networking aims at

providing a sound conceptual foundation with emphasis on the design aspects while adopting combination of the systems and top-down approaches. The course attempts to provide a balanced treatment of the state-of-the-art in the area and thus prepares the students for taking more rigorous and specialized courses in this and related fields. At the end of this course, students should be able to design, build and analyze simple networks using the application-driven paradigm.
