What is the difference between Mac OS X 10.6.5 Update Combo and "not combo"

Question

What is the difference between Mac OS X 10.6.5 Update Combo and "not combo"

I am running OS X 10.6.2 and wanted to download the new update and when I landed on the download page there were 2 updates:

"Mac OS X v10.6.5 Update" and "Mac OS X v10.6.5 Update (Combo)"

The first one is 644.48 MB.

The second one is 977.21 MB.

What is the difference between them?

Any help at al would be very appreciated!

iMac 20", Mac OS X (10.6.2), 2 Ghz Intel Core 2 Duo Processor, 4GB RAM

Hi,

The standard (called a 'delta' update) can be applied to one version back, e.g. the 10.5.7 delta update works only if you are running 10.5.6. 
The combo update will update from any previous version of the main OS release, e.g. 
the 10.5.7 combo update works if you are running 10.5.0 through 10.5.6 (but not, for example, 10.4.11).
The combo update can also be reapplied as a troubleshooting step (i.e. if you are having problems with 10.5.7, 
you can download and run the 10.5.7 combo updater).

Cheers.

the "combo" update means that you can update your system (from mac os 10.6 10.61 10.62 10.63 10.64) to the latest version(10.65)!!! so you need to download the "combo" one!!!
for me,my system is 10.64 ,I can chose either of the two updates
