Computer Networking & Network Security Course by Saurav Sinwar

This 7-week Computer Networking course takes students from the basics of what a network is all the way to designing and securing their own. It starts with foundational concepts like network types and devices, then builds up through the OSI and TCP/IP models, IP addressing, subnetting, routing, and switching. Students then dive into key protocols like DNS, HTTP, and SSH, followed by a dedicated week on network security covering firewalls, VPNs, and common attacks. The course wraps up with wireless networking, an intro to cloud infrastructure, and a final project where students design and present a complete network for a mock company. Throughout all 7 weeks, hands-on tools like Cisco Packet Tracer and Wireshark keep the learning practical and career-ready.
