In this lab we focused on the subnetting and it was very helpful to revise and being familiar to what we are studying in this course. Like for example, we knew, how to count the number of subnets from the network diagram, how to find the number of usable and unusable IP addresses and how to find the subnet mask as well. Lastly, we had implemented the network using Cisco Packet tr acer and it gave as a good experience about how to configure and test our implementation work
