An internet speed test is a tool that measures the performance of your internet connection. It typically assesses three main factors: download speed, upload speed, and ping (latency). Download speed indicates how quickly data can be transferred from the internet to your device, while upload speed measures how fast data can be sent from your device to the internet. Ping reflects the time it takes for data to travel to a server and back, which affects responsiveness during online activities. These tests can be conducted using various websites and applications, such as Speedtest by Ookla or Fast.com. Users can run a speed test to determine if their internet service provider (ISP) is delivering the promised speeds and to troubleshoot any connectivity issues. Regular testing can help ensure optimal performance for activities like streaming, gaming, and video conferencing.
