Nmap

Nmap (Network Mapper) is a tool used for analyzing computer networks. It scans devices connected to a network to identify what systems and services are running, such as websites, servers, or printers. By sending small messages to these devices and analyzing their responses, Nmap can determine aspects like open ports, operating systems, and security configurations. This helps network administrators manage, troubleshoot, or assess the security of their networks. In essence, Nmap acts like a digital sonar, mapping out what’s connected and how it’s configured within a network.
