What is Microsoft Office?

Microsoft Office is a set of programs that are used for office work. The most important, known and used are:

• MS Word - text processor. Used to create documents, reports, papers, etc.
• MS Excel - table processor. Used to create spreadsheets, etc.
• MS PowerPoint - presentation software. Allows you to impress your audience with colorful presentation full of pictures and graphs.
• MS Access - database program.

Then there are programs as MS Frontpage (to create static HTML pages), MS Binder but those I consider them not useful for me personaly, except maybe Frontpage.

It is a suite of common business office applications. Different versions of MS Office contain different components, but all contain at least a Word processor (Word), a spreadsheet (Excel), and a graphics presentation program (Power Point).

Some other programs available in more advanced versions of Office, include a database program (Access), an e-mail & calendar program (Outlook), and many other applications.
