What is service pack? - Definition from Whatis.com

A service pack is an orderable or downloadable update to a customer's software that fixes existing problems and, in some cases, delivers product enhancements. IBM and Microsoft are examples of companies that use this term to describe their periodic product updates.

When a new product version comes out, it usually incorporates the fixes from the service packs that have been shipped to update the previous product version.
