Internet Speed Test Analysis Guide
Everything you need to know about interpreting bandwidth, latency, and line consistency.
Download speed measures how quickly digital data travels from the internet to your device (crucial for streaming 4K video, downloading software, and loading web pages). Upload speed measures how rapidly data moves from your device to the internet (critical for video conferences, cloud backups, live streaming to YouTube or Twitch, and sending large attachments).
