Your upload and download speeds have a lot to do with how your device functions online. Typically, these speeds are measured in megabits per second (Mbps). How fast the data moves in either direction is the upload or download speed.

Uploading a picture to Facebook or Instagram, playing multiplayer online games in real-time and running video conference calls are all examples of activities that rely on the upload process.

When you stream videos or music or download an e-book or app, you’re engaging in the download process. The first is via download.ĭownloads occur when data comes from another device or the internet down to the local level on your device - in this case, specifically, your mobile phone.
