Speed testing is a process used to measure the performance of a network connection, typically focusing on internet speed. It evaluates how quickly data can be downloaded and uploaded, as well as the latency or delay in the connection. Users often utilize online tools or applications to conduct these tests, which provide results in megabits per second (Mbps). These tests are important for assessing the quality of service provided by internet service providers (ISPs) and can help users determine if they are receiving the speeds promised in their service plans. Regular speed testing can also identify issues that may affect online activities, such as streaming or gaming.
