User Reviews
"I've always used computers, but I never really understood how the internet works. This course demystified it all. Now I know what a router actually does, why my Wi-Fi gets slow, and how to use ping to test connections. Highly recommend for anyone who wants to stop feeling helpless when their internet goes down."
"Solid introduction. The module on IP addressing was very clear. I appreciated the interactive activities—they made abstract concepts concrete. The course is quite short, so don't expect to become a network engineer, but as a foundation, it's excellent. The Cisco badge is a nice touch."
"I'm studying for the CompTIA Network+ certification, and this course was a great warm-up. It covers the absolute basics in a very accessible way. The troubleshooting section with ping and tracert was practical and useful. I feel much more confident now moving on to more advanced topics."
