What is this folder "memory card sdcard0 Android "? topic

Sorry for asking a simple question as this, It could be answered before, But I did not find doing Google searches.

In the Phone Memory (not the external microSD) there is a folder named Android.
It has two folders in it, "data" and "obb".

\Memory card\Android\obb\
\Memory card\Android\data\

Is this like "program files" in windows? Or "/usr" for freebsd or linux file folder structure?
