Standalone Programs, Integrated Programs, & Software Suites „

Integrated programs provide all the leading productivity programs in one p package. g Advantages: „

Disadvantages: „

26

The programs within a suite share resources. The programs within a suite are designed to work together. These applications share common program code, interfaces, and drivers.
