Microsoft distributes fixes in service packs. Service packs keep a product current. They include hotfixes and software updates. Service packs may also include system administration tools, drivers, and additional components. These updates and components are conveniently bundled for easy downloading.
Service packs are cumulative. Each new service pack contains all the fixes that are in previous service packs, together with any new fixes. You do not have to install a previous service pack before you install the latest one. For example, you do not have to install Microsoft SQL Server 2005 Service Pack 1 (SP1) before you install Microsoft SQL Server 2005 Service Pack 2 (SP2).
