Introduction

Welcome to Packet Tracer 5.0.

Packet Tracer 5.0 is a standalone, medium-fidelity, simulation-based learning environment for networking novices to design, configure, and troubleshoot computer networks at a CCNA-level of complexity. Packet Tracer supports student and instructor creation of simulations, visualizations, and animations of networking phenomena. Like any simulation, Packet Tracer 5.0 relies on a simplified model of networking devices and protocols. Real computer networks remain the benchmark for understanding network behavior and developing networking skills. Packet Tracer was created to help address the "digital divide" in networking education, where many students and teachers lack access to equipment, bandwidth, and interactive modes of learning networking. We invite you to use the help files and tutorials to learn about the major features of the program, which include the items in the following table
