&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;OpenSim manifests itself in a few ways, the terminology can get confusing.&amp;#039;&amp;#039;&amp;#039; Here is my attempt at clearing up confusion and misunderstandings when attempting to refer to the software, and it&amp;#039;s various applications:&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Grid -&amp;#039;&amp;#039;&amp;#039; a community or network of individual simulators using some form of shared database for one or all of it&amp;#039;s grid services. A collection of independent Opensim Instances, Simulators, Sims, Regions, or Megaregions sharing a database or databases which handle assets and inventory for grid members. &lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Instance -&amp;#039;&amp;#039;&amp;#039; One example of Opensim running, on a server or PC, in what ever form as outlined below. Usually, but not always, contained inside a single directory.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Simulator, or sim for short -&amp;#039;&amp;#039;&amp;#039; One instance of Opensimulator, running anywhere from one region to hundreds.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Standalone -&amp;#039;&amp;#039;&amp;#039; A simulator or sim, running independently and not as part of a network of other simulators. Could be just a single region, or hundreds.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Standalone, Hypergrid mode -&amp;#039;&amp;#039;&amp;#039; A standalone sim which is networked and accessable by teleporting from other standalones or from other simulators in a grid, by way of simple changes in the OpenSim.ini config file.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Region -&amp;#039;&amp;#039;&amp;#039; Part of a Simulator, the main unit of a sim. Currently 256 x 256 meters, but other sizes are in the works for Opensim.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Parcel -&amp;#039;&amp;#039;&amp;#039; A subunit of a Region.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Megaregion -&amp;#039;&amp;#039;&amp;#039; a group of contiguous regions in one instance of Opensim without any restraints caused by borders. In effect, a group of anywhere from 2 to hundreds of regions configured to act as one single region. &amp;#039;&amp;#039;Note&amp;#039;&amp;#039;. Megaregions have been  replaced by VAR regions in august 2016 and are no longer supported. &lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Var Region-&amp;#039;&amp;#039;&amp;#039; a Var region is a Variable Size region. they can be 2x2 3x3 4x4 etc. They provide in a scalable environment without border crossings between the regions. &lt;br /&gt;
