Network Fundamentals

This lesson familiarizes the student with layered networking models (TCP/IP & OSI) and exposes them to basic networking concepts for both UNIX/Linux and Windows environments.  Additionally, it provides hands-on experience with a network protocol analyzer software tool (Wireshark) used to examine network traffic.

Learning Objectives
  • Understand layered network models
  • Understand basic concepts related to networking in Linux and Windows
  • Apply software tools such as Wireshark to examine network traffic
