event log name

Hello everyone,

I understand what is event log source name, i.e. mentioned here in MSDN -- "The event source indicates what logs the event. It is often the name of the application, or the name of a subcomponent of the application,  ..."

http://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog.lognamefromsourcename(VS.80).aspx

But what does the log name mean (in EventLog.LogNameFromSourceName API as mentioned in above link)?

thanks in advance,
George
