major & minor numbers
A little more context please..You must always face the curtain with a bow.
I assume you mean like the numbers in Firefox 3.6.9 for example?
Generally speaking, the major number indicates a significant release, often something with many pervasive changes, or potentially a complete rewrite. Backwards compatibility might be be broken. Moving from left to right, you get progressively less changes involved. Firefox 3.5 to 3.6 involved some new features, but the basics of the browser were the same. The minor point releases, like Firefox 3.6.8 to 3.6.9 are usually just bug fixes.
If this is about device nodes, then major number indicates what driver is in use and minor is the number of device.
For instance, first partition on first SATA drive is 8,1.
