Before they get away from me I want to start listing the builds of SharePoint 2010. To see which build your farm is, go to Central Administration > System Settings > Manage servers in your farm (/_admin/FarmServers.aspx)
Or using Windows PowerShell: (get-spfarm).buildversion
To see which build your products are, go to Central Administration > Upgrade and Migration > Check Product and patch installation status. (/_admin/PatchStatus.aspx)
To see which build your databases are, go to Central Administration > Upgrade and Migration > Review database status (/_admin/DatabaseStatus.aspx)
Patch terminology KB article.
