Computer Networks Syllabus Guide

This document contains the syllabus for a Computer Network subject taught as part of a Bachelor of Engineering degree in Computer Science and Engineering. It outlines the topics that will be covered across three units. Unit I introduces networking concepts like transmission technologies, network models, topologies and transmission media. It also covers physical layer topics. Unit II focuses on data link layer protocols and medium access control. Unit III discusses network layer routing, transport layer protocols, and application layer and network security topics. The document provides an overview of the key areas and concepts students will learn as part of this subject on computer networks.

CONTROLLED ACCESS

In controlled access, the stations consult one another to find which


station has the right to send. A station cannot send unless it has been
authorized by other stations. We discuss three popular controlled-access
methods.

Topics discussed in this section:


Reservation
Polling
Token Passing
Reservation access method
Select and poll functions in polling access method
Logical ring and physical topology in token-passing access method
