How does a speed test work?
A speed test measures how fast data travels between your device and a remote server. Download speed is how quickly you receive data — crucial for video streaming, file downloads, and web browsing. Upload speed measures how fast you can send data — important for file sharing, video calls, and cloud services.
Latency (ping) measures the round-trip time for a data packet between your device and the server. Low latency (< 20 ms) is essential for online gaming and video calls. Jitter measures the variation in latency — high jitter can cause stuttering in calls or streaming.
Results depend on many factors: your connection type (fiber, DSL, 4G/5G), distance to the server, network congestion, number of connected devices, and whether you use WiFi or Ethernet. For the most accurate results, close other applications and use a wired connection.
