* '''Node servers'''<br>Local Sugar Network servers that are intended to be distributed versions of the Master. This tutorial assumes that Nodes don't have direct connection to the Master, and the only one way to synchronize data is a [[wikipedia:Sneakernet|Sneakernet]].

* '''Database'''<br>Storage space where servers keep Sugar Network data. It might be removable device, e.g., SD card on a XO, or regular directory in the files system on a standalone school server. In all cases, the final directory name should be {{Code|sugar-network}}.

* '''Database media'''<br>Node servers might store database on removable devices (makes sense if Nodes are XO laptops), in that case, such devices should have a magic file, named {{Code|.sugar-network}}, in the root directory on removable device. Having this magic file will let Node's software auto detect recently plugged removable device as a Database media to start behaving correspondingly.

* '''Synchronization Media'''<br>Arbitrary removable media device, e.g., USB stick or SD card that will be used to transfer Packets between servers. In particular cases, Media might be a directory in the files system. In all cases, the final directory name should be {{Code|sugar-network-sync}}.

* '''Synchronization media'''<br>Removable media device, e.g., USB stick or SD card that will be used to transfer Packets between servers. Synchronization media should have a magic file, named {{Code|.sugar-network-sync}}, in the root directory. Having this file will let Node's software start synchronization process automatically after plugging media.

* '''Synchronization Packets'''<br>Regular files that contain synchronization data placed to Media. If synchronization happens using regular tools, Packet files will be named as {{Code|<server's-guid>-<server's-seqno>.packet}}. These files are [[wikipedia:Tar_(file_format)|tarballs]].
