COE-342 Data and Computer Communications

## Exam Dates:

Exam dates are:

• Major 1 on Thursday March 25th, 2004 -
• Major 2 on
• Final exam: To be scheduled by the Registrar

## Lecture Notes

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: Introduction, Topologies, and Protocols

Chapter 3: Fourier Analysis - These slides are still under development - not final.

In addition you can refer to the following handout:  Fourier Series Expansion and Filtering

Chapter 4: Transmission Media  or the new edition slides

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: Data Communication Interface (Asynchronous/synchronous Transmission, V.24/EIA-232-F, ISDN interface)

Chapter 7: Data Link Control (Flow/Error Control Schemes and HDLC)

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/

## Handouts:

1. Periodic signals - Period T and the relationship with the fundamental frequency f
2. The DC component of a signal - The power of a periodic signal
3. The Fourier series expansion of a periodic signal
4. Computing the power of a signal using its Fourier series expansion - Computation of power of truncated signals
5. Low/Band/High pass filtering (ideal)
6. Introduces MATLAB programming language (code included in document)

## Announcements:

• WebCT:

Student's WebCT ID: Same as their KFUPM student ID's

Please note that WebCT ID created for any student last semester is still effective. If a student has forgotten his password then please contact at webcourses@kfupm.edu.sa to request password reset. New WebCT ID's have been created for those students whose IDs were not previously registered on the server. Please inform your students that if they did not have a WebCT ID before then it is same as their KFUPM ID with password as given below:

Initial password: Same as their KFUPM student ID's
