MICROSOFT OFFICE FOR HOME & BUSINESS
Because there are so many applications to choose from, and because not every user needs all of them, Microsoft groups the applications together in collections called suites. There is a suite of applications for students, a suite for home and small business users, and a suite for large corporations. There is even a suite for schools. Each of these suites is priced based on what is included in it.
