Uploading and downloading
The upload [ ʌp.ləʊd ] (upload of English, for uploading or uploading ) referred to in the computer science data flow from the local computer or local storage to a remote computer. The data flow in the other direction is referred to as a download or in accordance download. Within the framework of transmitting data over the Internet, the process is referred to as upstream (of English upstream).
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.
The uploading of data can be done through various network protocols, such as HTTP or FTP. The latter transferred the data is unencrypted, which is why each of the secure counterpart HTTPS and SFTP applies.
