Network Troubleshooting
Network troubleshooting is a systematic process of diagnosing and resolving issues in computer networks to restore connectivity, performance, and security. It involves identifying problems in network components like routers, switches, cables, and protocols, using tools and methodologies to isolate faults. This skill is essential for maintaining reliable communication in IT infrastructure, from local networks to cloud services.
Developers should learn network troubleshooting to debug connectivity issues in applications, optimize performance in distributed systems, and ensure security in networked environments. It's critical when deploying web services, managing cloud infrastructure, or working with microservices, as network problems can cause downtime, slow responses, or data breaches. Mastering this helps in roles like DevOps, site reliability engineering, or backend development where network reliability is key.
