Welcome to CS420/520 Data Communication. This web-page contains information about the course, e.g. syllabus, class notes, pointers to interesting places etc. Material can be down-loaded in postscript and pdf format, and will be made available as the class goes on.

• Live-taped: Tuesday 1:30-2:20, Thursday 12:30-2:20, JEB 021.
• This class has a CS341 (operating systems) co-requisite.

• Fall 1999 Term Class Handouts:
  • The handout numbers refer to the lecture in which the handout was made available. This does not necessarily mean that this material was covered in this particular lecture. (Most likely there is some overlap).
  • If there are any problems with accessing the handouts, please let me know (email, phone, smoke signs, drums, ...)!
  • Corrections: some slides may contain formatting errors, typos etc. which have been addressed in class, but have not been reflected in the notes posted here.
  • Need a ghostscript or pdf viewer? (check out Aladdin Ghostscript (use a search engine to get the newest version), adobe acrobat).

  • WARNING LOCAL STUDENTS: Do not send pdf files (i.e. files in pdf format) to the printer! Pdf files are binary files and printing them "directly" will result in a big printer mess!!! There are 2 ways to look at or print the pdf notes:
    • Save the file and use acroread (usr/local/bin/acroread) to open it. Then from within acroread use the print option.
    • Better: update netscape to use pdf files. To do this go to "edit - preferences", then expand "Navigator" and click "Application". Next click "New" and fill in the following: Description: acroread, MIMEType: application/pdf, Suffixes: pdf. Then click on "application" and enter: /usr/local/bin/acroread %s
    • Now "OK" out of it and it should work.
