Network Simulators
Network simulators are software applications that allow engineers to create, configure, and test virtual network topologies without needing physical hardware. By modeling the behavior of devices like routers, switches, and firewalls, these tools enable the practice of complex configurations, troubleshooting scenarios, and protocol analysis in a safe, controlled environment. They serve as a practical platform for verifying network designs and preparing for certification exams by emulating various operating systems and network conditions.
