Packet Tracer

Packet Tracer is a simulation tool used by networking students and professionals to design, test, and visualize computer networks without physical hardware. It allows users to create virtual network topologies, configure devices like routers and switches, and observe how data flows through the network. This helps in understanding complex networking concepts, practicing configurations, and troubleshooting issues in a safe, cost-effective environment. Packet Tracer is widely used for education and training, providing an interactive way to learn about network operations without the need for real equipment.
