Course Content

Network Types & Topologies, introduces learners to the various forms of computer networks—such as LANs, WANs, and VPNs—and explores how devices are interconnected through different layouts like star, mesh, and ring topologies, each with unique advantages and use cases.

IP Addressing & Subnetting, equips learners with the knowledge to identify, assign, and organize IP addresses within a network by exploring IPv4 and IPv6 structures, subnet masks, CIDR notation, and the logic behind dividing large networks into smaller, more efficient segments.

DNS, DHCP & Routing Fundamentals, unpacks the critical services that keep networks functional—explaining how domain names are translated into IP addresses via DNS, how devices automatically receive network configurations through DHCP, and how routers direct data between networks using routing tables and gateways.

Network Hardware – Routers, Switches & Firewalls, delves into the physical components that form the backbone of any network, helping learners understand how devices like routers manage traffic between networks, switches direct data within a local network, and firewalls act as gatekeepers that monitor and control incoming and outgoing traffic for security.

Troubleshooting Tools & Practical Scenarios, gives learners a hands-on approach to identifying, diagnosing, and resolving common network issues using essential tools like ping, tracert, ipconfig, and Wireshark, while reinforcing problem-solving strategies through real-world case simulations and guided decision-making exercises.
