Case Study:

Installing network simulator (packet Tracer)

Creating simple network scenarios

Configuring PC’s with IP addresses subnet mask and gateway

Configuring switches by giving name to switches and management IP addresses

Connection PCs to switch and then ping each other` that they are working properly.
