netstat:tldr:bacc1

The command "netstat -o" is a command-line tool used in Windows operating systems to display active network connections, listening ports, and related information. It stands for "network statistics" and the "-o" option is used to show the process identifier (PID) associated with each connection.

When you run the "netstat -o" command, it provides you with a list of established TCP connections, listening ports, and UDP endpoints, along with the Process ID (PID) of the application or service that has established or is using that particular network connection. This can be helpful in identifying which process or application is using a specific network resource or causing network traffic.

The output of the command typically includes information such as local and remote addresses, protocol used, state of the connection (established, listening, waiting), and the associated PID. By cross-referencing the PID with other system monitoring tools or task managers, you can determine which application or service is responsible for a specific network connection.
