Network engineering courses can help you learn network design, troubleshooting, security protocols, and performance optimization. You can build skills in configuring routers and switches, implementing firewalls, and managing network traffic. Many courses introduce tools like Cisco Packet Tracer, Wireshark, and various network monitoring software, that support applying your skills in real-world networking environments.
