Stop reading about networks. Start building one.
Computer Networking II is the hands-on continuation of Computer Networking I — where theory becomes real configuration. Across 17 weekly sessions, you'll build, secure, and maintain a single, continuously-growing company network in Cisco Packet Tracer: Mboa Group, a fictional Cameroonian organization that expands from one office in Douala into a four-site enterprise spanning a corporate headquarters, a school, a government partnership, and a smart-city IoT pilot.
What you'll build:
- Core device configuration: CLI fundamentals, interface addressing, and basic security from day one
- VLANs, trunking, and inter-VLAN routing to segment a real organization
- Redundancy with EtherChannel and HSRP, so no single device failure takes down the network
- DHCP, static routing, and OSPF dynamic routing connecting multiple physical sites
- Access Control Lists and NAT/PAT securing and connecting the company to the outside world
- A site-to-site VPN encrypting sensitive government traffic
- Wireless configuration, real Identity and Access Management (SSH, named accounts, no shared passwords), and SNMP monitoring across every site
- IoT device integration for a smart-city deployment
- Systematic, layer-by-layer troubleshooting — diagnosing and fixing real, deliberately-introduced faults
Computer Networking I
Learn how the internet actually works — from the ground up, with no prior experience required.
Computer Networking I is a complete, theory-first foundation course designed to take you from "what is a network?" to genuinely understanding how data travels across the internet — the hardware behind it, the addresses that identify every device, the protocols that keep it reliable, and the math behind subnetting a real network by hand.
Delivered by Aloge Allen through NeoCohorts, this course is built specifically for students starting with zero networking background. Every concept is grounded in examples you already live with daily — MTN Mobile Money, CAMTEL's fiber backbone, WhatsApp calls, campus Wi-Fi — so abstract ideas stay concrete from day one.
What you'll learn:
- The core vocabulary of networking: communication, protocols, and networking itself
- Real hardware — routers, switches (unmanaged, smart, and managed), access points, and more
- How every device gets its identity: MAC addresses, IP addresses, and subnetting — calculated entirely by hand
- Transmission media, wireless access, and how one connection serves many devices at once
- The layer model that organizes the entire internet, and what's actually inside a network packet's headers
- How data reaches its destination reliably: TCP, UDP, routing, and error detection
- Real-world performance: bandwidth, latency, and why some connections feel faster than others
- Security fundamentals: common threats and the defenses that counter them
