TCP/IP courses can help you learn networking fundamentals, data transmission protocols, and the architecture of the internet. You can build skills in configuring network devices, troubleshooting connectivity issues, and implementing security measures. Many courses introduce tools like Wireshark for packet analysis, Cisco routers for practical networking experience, and command-line interfaces for managing network settings.
