Packet Tracer Software
Packet Tracer is software developed by Cisco to facilitate learning computer networking construction and configuration. The software is free and available (and recommended) to all students in my Networking classes. Students are encouraged to bring in a portable flash drive to install the software and to use as transport for the various lab we do in class.
