BACHELOR OF ENGINEERING (B.E) - PEARL - 08-16-2017
BACHELOR OF ENGINEERING (B.E)
Aim:
The objective of the course on Data Communications and Networking is to provide a foundation to
the course on Computer Networks. The coverage includes concepts related to signals, data
communications, shared assess of media /links, error detection and correction. The course concludes
with reference to layered architecture of computer networks and a detailed exposure to data link
control, medium access control and a few technologies related to connectivity devices.

Scheme of Semester End Evaluation
Students have to answer 5 questions choosing at least 2 out of 4 questions
from Part A and 2 questions out of 4 questions from Part B.
Outcome:
A clear understanding of the basic features of peer-to-peer network s and important concepts are
achieved. Thus enabling the student to persue a cause on computer networks.
