Ping measures the time it takes for data to travel from your device to a server and back. Lower ping values indicate better network responsiveness, which is important for online gaming, video calls, and real-time applications. A ping under 20ms is excellent, while anything over 100ms may cause noticeable delays.
It's recommended to test your internet speed regularly, especially if you experience connection issues or want to verify your ISP's performance. Weekly tests can help you track performance over time and identify patterns or problems with your connection.
Download speed determines how fast you can receive data (streaming, browsing, downloading files), while upload speed determines how fast you can send data (video calls, uploading files, live streaming). Most internet plans offer faster download speeds than upload speeds, as most users download more than they upload.
