Network Diagnostics refers to the process of identifying and resolving issues within a computer network. It involves using various tools and techniques to analyze network performance, connectivity, and configuration. Common problems include slow internet speeds, dropped connections, and hardware malfunctions. To perform Network Diagnostics, technicians may use software tools that test network paths, check for packet loss, and measure latency. These diagnostics help pinpoint the source of issues, whether they stem from routers, switches, or cables. By diagnosing problems effectively, networks can be optimized for better performance and reliability.
