Checking which ports are open on a computer system involves identifying the ports that are actively listening for incoming network connections. This process is essential for network troubleshooting, security audits, and managing network resources effectively.
Understanding which ports are open provides valuable insights into the system’s network configuration, potential vulnerabilities, and the services running on the computer. It enables network administrators to identify and address security risks, such as unauthorized access attempts, malware infections, and denial-of-service attacks that exploit open ports.
