Port usage refers to the utilization of specific ports, which are virtual connections established between two devices over a network. Checking port usage involves monitoring and identifying which ports are active or inactive on a computer or network device. This process helps in troubleshooting network issues, identifying security vulnerabilities, and optimizing network performance.
Understanding port usage is crucial for maintaining a secure and efficient network. By identifying active ports, system administrators and network engineers can detect unauthorized access, malware infections, or misconfigurations that could compromise the security of a system or network. Additionally, monitoring port usage provides insights into network traffic patterns, allowing for the identification of performance bottlenecks and optimization of resource allocation.
