Checking ports being used is the process of identifying which ports on a computer are currently in use. This information can be useful for troubleshooting network issues, identifying security risks, and optimizing network performance.
There are a number of different ways to check ports being used. One common method is to use the netstat command. Netstat is a command-line tool that can be used to display a list of all active network connections. Another method is to use a network scanner. Network scanners are software programs that can scan a network for open ports.
