Cisco Packet Tracer is a  powerful network simulation program that allows students to experiment  with network behavior and ask “what if” questions. As an integral part  of the Networking Academy comprehensive learning experience, Packet  Tracer provides simulation, visualization, authoring, assessment, and  collaboration capabilities and facilitates the teaching and learning of  complex technology concepts.
Packet Tracer  supplements physical equipment in the classroom by allowing students to  create a network with an almost unlimited number of devices, encouraging  practice, discovery, and troubleshooting. The simulation-based learning  environment helps students develop 21st century skills such as decision  making, creative and critical thinking, and problem solving.
Packet Tracer  complements the Networking Academy curricula, allowing instructors to  easily teach and demonstrate complex technical concepts and networking  systems design. With Packet Tracer, instructors can customize individual  or multiuser activities, providing hands-on lessons for students that  offer value and relevance in their classrooms. Students can build,  configure, and troubleshoot networks using virtual equipment and  simulated connections, alone or in collaboration with other students.  Most importantly, Packet Tracer helps students and instructors create  their own virtual “network worlds” for exploration, experimentation, and  explanation of networking concepts and technologies.
Packet Tracer activities are included in the CCNA Discovery, CCNA Exploration, and CCNA Security curricula to provide rich networking technology learning experiences.
