For many Internet applications is an example ADSL usual reception-transmission ratio ( "Download upload " ) ratio of the data rate of 8:1 (previously 6:1) sufficient, as more data are received by the local computer as sent. For Internet users, who often upload or send multimedia files, but it is recommended to increase the transmission rate ( " upload rate " ), for example via an SDSL line (this is the data rate in both directions the same).

The origin of the word is not clear. Probably I'll use a picture of a " target computer " as a model, standing on a mountain or on a satellite and is visible to all. For this calculator, the data should be pushed up. Another approach is the one that your host is seen as a slave device on the network.
