Microsoft Office

Microsoft Office is an office suite of applications, servers, and services developed by Microsoft. It was first announced by Bill Gates on August 1, 1988, at COMDEX in Las Vegas. Initially a marketing term for a bundled set of applications, the first version of Office contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, OLE data integration and Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applicationsbrand.

On 10 July 2012, Softpedia reported that Office is used by over a billion people worldwide.

The desktop version of Office is available for Windows and OS X. A touch-optimised version of Microsoft Office is available pre-installed on Windows RT tablets. A mobile version of Office, Office Mobile, is available for free onWindows Phone, iOS and Android. A web-based version of Office, Office Online, is also available. Microsoft has stated that it plans to create a version of Office for "other popular platforms" as well.

The current desktop version is Office 2016 for Windows and OS X, released on 22 September 2015 and 9 July 2015, respectively.

Desktop components

Word

Microsoft Word is a word processor available for Windows and OS X. Word is also available in some editions ofMicrosoft Works. The first version of Word, released in the autumn of 1983, was for the MS-DOS operating system and had the distinction of introducing the mouse to a broad population. Word 1.0 could be purchased with a bundled mouse, though none was required. Following the precedents of LisaWrite and MacWrite, Word for Macintosh attempted to add closer WYSIWYG features into its package. Word for Mac was released in 1985. Word for Mac was the first graphical version of Microsoft Word.

Its proprietary Doc format is a de facto standard, although Word 2007 deprecated this format in favor of Office Open XML, which was later standardized by Ecma International as an open format. Support for Portable Document Format (PDF) and OpenDocument (ODF) was first introduced in Word for Windows withService Pack 2 for Word 2007.

Excel

Microsoft Excel is a spreadsheet program that originally competed with the dominant Lotus 1-2-3, and eventually outsold it. It is available for the Windows and OS X platforms. Microsoft released the first version of Excel for the Mac OS in 1985, and the first Windows version (numbered 2.05 to line up with the Mac and bundled with a standalone Windows run-time environment) in November 1987. It provided more functionality than the previous version.

PowerPoint

Microsoft PowerPoint is a presentation program for Windows and OS X. It is used to create slideshows, composed of text, graphics, and other objects, which can be displayed on-screen and shown by the presenter or printed out on transparencies or slides.

Access

Microsoft Access is a database management system for Windows that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. Microsoft Access stores data in its own format based on the Access Jet Database Engine. It can also import or link directly to data stored in other applications and databases.

Outlook

Microsoft Outlook (not to be confused with Outlook Express) is a personal information manager. The replacement for Windows Messaging, Microsoft Mail, andSchedule+ starting in Office 97, it includes an e-mail client, calendar, task manager and address book.

On the Mac OS, Microsoft offered several versions of Outlook in the late 1990s, but only for use with Microsoft Exchange Server. In Office 2001, it introduced an alternative application with a slightly different feature set called Microsoft Entourage. It reintroduced Outlook in Office 2011, replacing Entourage.

OneNote

Microsoft OneNote is a freeware notetaking program. It gathers notes (handwritten or typed), drawings, screen clippings and audio commentaries. Notes can be shared with other OneNote users over the Internet or a network. OneNote was initially introduced as a standalone app that was not included in any of Microsoft Office 2003 editions. However, OneNote eventually became a core component of Microsoft Office; with the release of Microsoft Office 2013, OneNote was included in all Microsoft Office offerings before eventually becoming completely free of charge. OneNote is available as a web application on Office Online, a Windows desktop app, a mobile app for Windows Phone, iOS, Android, and Symbian, and a Metro-style app for Windows 8 or later.
