Network analysis tools are software applications designed to monitor, analyze, and visualize computer networks. They help network administrators understand traffic patterns, identify bottlenecks, and troubleshoot issues. Common features include real-time monitoring, data packet analysis, and performance metrics, which assist in maintaining network efficiency. These tools can also enhance security by detecting unusual activities or potential threats within the network. Popular examples of network analysis tools include Wireshark, SolarWinds, and Nagios. By using these tools, organizations can ensure their networks run smoothly and securely, ultimately supporting better communication and productivity.
