What does the Netstat command provide information about?

The Netstat command is a network utility that provides detailed information about network connections on a computer. Specifically, it outputs data regarding the active ports and incoming connections, which is essential for diagnosing network issues and managing network security.

Upon executing the Netstat command, users receive a list of all network connections, along with the local and remote addresses, the state of the connections (such as listening, established, or closed), and the associated ports being used. This information is crucial for monitoring and ensuring that only legitimate applications are communicating over the network and helps in identifying unauthorized access attempts.

In contrast, while the other options mention different aspects of network management and monitoring, they do not accurately describe the information provided by the Netstat command. Active applications on the local system pertains more to task management than network management, total network traffic over a period relates to bandwidth analysis which is handled by different tools, and network signal strength is relevant to wireless connectivity status, not to the details of established network connections. Thus, the primary focus of the Netstat command is on ports and incoming connections, making the answer valid.
