packet sniffer

A packet sniffer is a tool used to monitor and analyze data packets that travel across a network. Just like a postal service can inspect letters, a packet sniffer captures the data being sent and received, allowing users to see details such as sender, recipient, and content. This helps network administrators troubleshoot issues, ensure security, or analyze traffic patterns. While packet sniffers are valuable for legitimate purposes, they can also be misused for unauthorized data interception, highlighting the need for proper security measures in network management.
