Bandwidth Testing is the process of measuring the maximum data transfer rate of a network connection. It helps determine how much data can be sent or received over a specific period, usually expressed in bits per second (bps). This testing is essential for assessing the performance of internet connections, ensuring they meet the required standards for various applications. During Bandwidth Testing, tools and software are used to send data packets across the network. The results indicate the speed and reliability of the connection, helping users identify potential issues like congestion or inadequate service. This information is crucial for optimizing network performance and improving user experience.
