What is the Difference Between Download and Upload Speeds?

Download speeds measure how fast your internet is at receiving information, like downloading and streaming. This affects things like watching a YouTube video, streaming a 4K TV show, or listening to your favorite song on Spotify. Upload speeds affect how fast your internet can send information. This affects how quickly you can upload a video to YouTube, send a large file to a coworker, the quality of your Zoom / video meetings, and how much lag you will experience when online gaming.
