Yes, it is for the cell. As Ram sir has specified, there are no updates in
HBase per se. You either put a new version or delete the old data and put
the new data in the same cell. Along with the link specified by Ram sir, I
would suggest you to go through this as well :
http://hbase.apache.org/book/versions.html

There are no updates.  It just adds one more version to the existing row.
 You can try out from the HBase shell.

http://hbase.apache.org/book.html - will give an idea on the design and
architecture.
