Which tool is used to measure the performance of an internet connection?

The bandwidth speed test tool is designed specifically to measure the performance attributes of an internet connection, such as download and upload speeds, latency, and sometimes jitter. This tool operates by sending a series of data packets to a server and measuring how long it takes for them to be sent and received. The results provide a clear indication of the connection's performance metrics, which are essential for troubleshooting and assessing the quality of service that users are experiencing.

The other tools have specific functions that do not focus primarily on measuring internet connection speed. A network switch facilitates the connection of devices within a local network and does not measure connection performance. A signal strength meter typically assesses the strength of a wireless signal rather than the speed of an internet connection. A packet sniffer captures and analyzes data packets traversing a network but does not inherently measure bandwidth or speed; its primary purpose is to provide insights into network traffic and data flow.
