download vs. upload

Download and upload (downstream and upstream) speeds may be the same or very different. In a local network, sending a file and receiving a file are transmitted at the same speed. Transmission speeds to and from the Internet are not necessarily the same. It depends on the provider and type of service being subscribed to. For example, business customers may have the same download/upload speeds, while residential customers generally have much higher download speed to prevent consumers from operating an Internet service.

Consumers - Little Up - A Lot Down
A Web page is requested with a very little amount of data going to the Web server, but the content coming back can be 100 times as much. Video is even a more extreme example. A small data request can retrieve a couple hours worth of content (hundreds of megabytes of data). See download and UL/DL ratio.
