An upload is the act of sending files from a local workstation to a remote workstation or server.
The File Transfer Protocol (FTP) is the Internet facility for downloading and uploading files. (If you are uploading a file to another site, you must usually have permission in advance to access the site and the directory where the file is to be placed.)
|Dial-up: Up to 54 Kb/s|
|DSL: 54-2000 Kb/s|
The opposite of this activity is called, downloading. Uploading is usually slower than downloading. This is due to the bottleneck at the modem, though upload speeds are also often throttled (limited) by the internet service provider.
