Introduction to Computer Networks

Description

This course introduces the basic concepts and principles underlying packet-based networks, including circuit switching & packet switching, structure of computer networks, types of computer networks. In addition, examples of standard technologies and protocols are given to illustrate the concepts. 

Prerequisites

CS 140 or equivalent.

Topics include

• Layered protocol architecture, OSI reference model, and the internet architecture
• The physical layer: Theoretical basis for data communications, signaling and modulation, multiplexing, transmission media, physical interfaces and protocols
• The data link layer: Error control, cyclic redundancy check, the sliding window flow control mechanism, performance considerations, bit-oriented data link control protocols (HDLC)
• MAC layer bridging and spanning tree protocol
• The network layer: addressing, services (datagram, virtual Circuit), routing algorithms (Bellman Ford, Dijkstra), congestion control, the internet protocol (IP)
• The transport layer: UDP, TCP, TCP congestion control
• The application layer: FTP
