Network simulator

A network simulator is like a video game for computers. It's a computer program that allows someone to create a model of a computer network, which can be used to test different kinds of activities and security in the network. It can be used to help network administrators and engineers to understand how different types of computer networks work and also to test out different ideas or scenarios before making any changes to the real network. A network simulator can also help you practice setting up and troubleshooting network problems.
