2010-05-16 Finally updated the module TCP and UDP. Sorry for keeping an old version for so long; now it contains the most important issues about Internet's transport layer.

Wireless LAN

I am currently working on a more actual documentation which also covers actual topics in more detail, including OFDM, LWAPP, other security issues, management, and site survey. But for now the following modules should be a good start for beginners because they cover most of the fundamental issues of WLANs in a not too technical level, however precise enough for daily practice.

DCOM Basics

The following (widely appreciated :-)) lecture notes have been created between 2003 and 2005 and have proved oneself to provide both an efficient introduction into modern data communication and a compact reference book for self study. Future updates will be marked differently somehow to avoid duplicate downloads. You can use these modules freely for you private purposes but please contact me if you have other plans.

Most of this content follows Manfred Lindner's outline and didactical approach. I hereby want to express my gratitude to him, especially for his excellent lectures.

Cisco Configuration Cheatsheet

If you ever plan to become a CCNA first visit the ICND exams, buy the CCNA Certification Libary from CiscoPress but definitely get some hands-on experience. Simply check whether you know all the commands listed in my: *Cheat Sheet*.
