Internet service providers usually give you two speed of data transfer - Download and Upload.
Download speeds are usually at least double, or more, that of upload speeds.
Download speed is usually the speed you can browse and download Internet content. Most of our Internet activity is through downloading content.
Upload speed is mostly an issue when you are sending files and email to other servers. It is the rate you are sending data out from your computer to the Internet (versus downloading). Uploading us usually much slower than downloading speeds.
Upload speed can also be an issue if you are using VoIP services.Source(s): http://www.speedtest.net/
