Spell Immunity vs Spell Resistance

I really don't know how to compare the two, the only thing that I could find was that its the same thing, but Spell Immunity cannot be overcome. What does that mean?

Spell Immunity is treated like a Spell Resistance of Infinity.

Spells with the entry of "Spell Resistance: No" bypass SR.

From the D&D Glossary:
"A creature with spell immunity avoids the effects of spells and spell-like abilities that directly affect it. This works exactly like spell resistance, except that it cannot be overcome. Sometimes spell immunity is conditional or applies to only spells of a certain kind or level. Spells that do not allow spell resistance are not affected by spell immunity. Spell immunity is usually an extraordinary ability."
