The performance of an Internet connection, which is based on the number of bytes per second that data travels from the user's device to the Internet (upload) and from the Internet (download). Depending on the type of connection, the speed differs dramatically. The download rate is higher than the upload, because a short request to the website (upload) results in a much larger download of Web pages, images and videos. Pricing Internet access via cable, DSL, FiOS and satellite is priced on maximum download/upload speeds. Pricing from a cellular carrier is based on bytes of data transfer in both directions (see carrier data plans), and the download speed can vary significantly depending on current location and activity.
