Exam dates are:
Students are responsible for the material in the textbook and that in the handouts, if any. The class notes and slides are just "notes"; they may not cover all required material. The book is the reference for the required material.
Below are a set of electronic class notes that are based on the textbook.
Chapter 1: Data Communications and Networking Overview
Chapter 2: The OSI Reference Model and the TCP/IP Stack
Chapter 3: Fourier Analysis - These slides were updated Feb 2013 - More material on Fourier Transform and Z-Transform is added.
In addition you can refer to the following handout: Fourier Series Expansion and Filtering
Data, Signals and Transmission ; solved examples/problems on Chapter 3 material;
Chapter 4: Transmission Media
These slides are originally for Stallings - I just added some explanatory text and modern (colored) illustrations
Chapter 5: Data Encoding - Modulation Techniques
Animation for PCM (the animations were provided by Forouzan)
Chapter 6: Digital Data Communication Techniques: Asynchronous/synchronous Transmission, Error Detection, and Error Coding (optional)
Chapter 7: Data Link Control (Flow/Error Control Schemes and HDLC) - ARQ design problems.
Animations for: stop-and-wait protocol, sliding-window protocol, CRC calculation, and HDLC (the animations were provided by Forouzan)
Chapter 8: Multiplexing (FDM and TDM)
Animations for: FDM, TDM, and Statistical TDM (the animations were provided by Forouzan)
These are the set of notes provided by the publisher. The original power point files are found at: ftp://ftp.prenhall.com/pub/esm/computer_science.s-041/stallings/Slides/DCC6e-Slides/
