Microsoft PowerPoint 
Microsoft PowerPoint or Microsoft Office PowerPoint or PowerPoint is a computer program for presentations developed by Microsoft in their suite of office applications, Microsoft Office, in addition to Microsoft Word, Excel, Access and several other programs. PowerPoint runs on a PC computer based on Microsoft Windows operating system and also Apple Macintosh that uses Apple Mac OS operating system, although at first this application runs on the Xenix operating system. This application is very widely used, especially by the office and businesspeople, educators, students, and trainers. Beginning on the version of Microsoft Office System 2003, Microsoft changed the name of Microsoft PowerPoint to Microsoft Office PowerPoint. Then, in Office 2013, its name is simply shortened to PowerPoint. The latest version of PowerPoint is version 15 (Microsoft Office PowerPoint 2013), which is incorporated into the Microsoft Office 2013 package.

histori
The Microsoft PowerPoint application was first developed by Bob Gaskins and Dennis Austin [1] [2] as a Presenter for a company called Forethought, Inc. which they later renamed to PowerPoint. [3]

In 1987, PowerPoint 1.0 version was released, and the computer it supports is Apple Macintosh. At that time, PowerPoint still uses black / white, which is able to create text and graphic pages for overhead projector (OHP) transparency. A year later, a new version of PowerPoint came with color support, after a color Macintosh appeared on the market.

Microsoft acquired Forethought, Inc. and of course PowerPoint software for a price of approximately $ 14 million on July 31, 1987. In 1990, a version of Microsoft Windows from PowerPoint (version 2.0) came into the market, following in the footsteps of Microsoft Windows 3.0. Since 1990, PowerPoint has become an integral part of standard in Microsoft Office System office suite (except Basic Edition).

The latest version is Microsoft Office PowerPoint 2013 (PowerPoint 15). This version was released in January 2013, which is a considerable leap in terms of user interface and enhanced graphics capabilities. In addition, compared to previous data formats that are binary data with the extension * .ppt, this version offers an XML data format with * .pptx extension.

Microsoft Excel
Microsoft Excel or Microsoft Office Excel is a spreadsheet spreadsheet application program created and distributed by Microsoft Corporation that can run on Microsoft Windows and Mac OS. This application has a feature of calculation and graphics that, using the aggressive Microsoft marketing strategy, makes Microsoft Excel as one of the popular computer programs used in microcomputers to date. In fact, this program is currently a spreadsheet program most widely used by many parties, both on Windows-based PC platform and Mac OS based Macintosh platform, since version 5.0 was published in 1993. This application is part of the Microsoft Office System, and the latest version is version of Microsoft Office Excel 2013 that is integrated in the package of Microsoft Office System 2013.


History
In 1982, Microsoft created a spreadsheet program called Multiplan, which is very popular in CP / M systems, but not in the MS-DOS system considering there already stands its rival, the Lotus 1-2-3. This led Microsoft to start developing a new spreadsheet program called Excel, with the aim, as Doug Klunder says, "do everything 1-2-3 does and do it better / does what it does 1-2-3 and better yet ".

The first version of Excel was released for the Macintosh in 1985 and its Windows version followed (numbered version 2.0) in November 1987. Lotus was late for the spreadsheet program market for Windows, and in that year Lotus 1-2-3 was still MS- DOS. In 1988, Excel began to shift 1-2-3 in the market share of spreadsheet programs and make Microsoft as one of the leading software application developers for personal computers that are reliable. This achievement confirms Microsoft as a very strong competitor for 1-2-3 and even they develop it better. Microsoft, using its advantages, releases new versions of Excel every two years, and the latest version of Excel for Windows is Microsoft Office Excel 2010 (Excel 14), while for Macintosh (Mac OS X), the final version is Excel for Mac.

In the early days of its launch, Excel was subjected to the demands of other companies engaged in the financial industry that had sold a software that also had the name Excel. Finally, Microsoft ended the demands with defeat and Microsoft had to rename Excel to "Microsoft Excel" in all Microsoft press releases and documents. However, in practice, this is ignored and even Microsoft bought Excel from the company that previously demanded them, so the use of the Excel name alone will not bring any more trouble. Microsoft also often uses the letters XL as an abbreviation for the program, which although not common, the icon used by the program still consists of two letters (although given some style of writing). Additionally, the default extension of a spreadsheet created by Microsoft Excel to version 11.0 (Excel 2003) is * .xls whereas starting Microsoft Office Excel 2007 (version 12.0) its default extension is * .xlsx that supports HTML format but with the same content has a smaller file size when compared with previous versions of Excel.

Excel offers many interface advantages compared to previous spreadsheet programs, but the essence is still the same as VisiCalc (the famous spreadsheet software for the first time): Cells are arranged in rows and columns, and contain data or formulas with absolute references or references relative to other cells. Excel is the first spreadsheet program that allows users to define how views of the spreadsheets they edit: fonts, character attributes, and the appearance of each cell. Excel also offers intelligent recalculation of cells, where only cell-related cells will be updated (where other spreadsheet programs will recalculate the entire data or wait for a specific command from the user). In addition, Excel also offers excellent graphics processing features.

When first bundled into Microsoft Office in 1993, Microsoft redesigned the interface display used by Microsoft Word and Microsoft PowerPoint to match the look of Microsoft Excel, which at that time became the most preferred spreadsheet application. Since 1993 Excel has had a Visual Basic for Applications (VBA) programming language, which can add Excel's ability to automate in Excel and also add user-defined functions (UDF) for use in in the worksheet. In later versions, Microsoft even added an integrated development environment (IDE) for the VBA language for Excel, making it easier for programmers to create their own programming. In addition, Excel can also record all that is done by the user to become a macro, so it is able to automate some tasks. VBA also allows the creation of forms and controls contained in the worksheet to communicate with its users. VBA languages ​​also support the use of ActiveX / COM DLLs, although they can not create them. The VBA version further adds support to the class module thus allowing the use of object-oriented programming techniques in VBA

The automation function provided by VBA makes Excel a target for macro viruses. This is a very serious problem in the corporate world until antivirus makers start adding support to detect and clean macro viruses from Excel files. Finally, though too late, Microsoft also integrates functions to prevent misuse of macros by disabling macros in its entirety, or disabling macros when enabling workbooks, or trusting encrypted macros using trusted digital certificates.

Microsoft Word
Microsoft Word or Microsoft Office Word or Word is Microsoft's flagship word processing software (word processor). First published in 1983 under the name Multi-Tool Word for Xenix, other versions were later developed for various operating systems, such as DOS (1983), Apple Macintosh (1984), SCO UNIX, OS / 2, and Microsoft Windows (1989). After becoming part of Microsoft Office System 2003 and 2007 was named Microsoft Office Word. In Office 2013, its name is simply called Word.

Many Word ideas and concepts are drawn from Bravos, the first graphics-based word processor developed at Xerox Palo Alto Research Center (PARC). Bravo creator Charles Simonyi left Xerox PARC and moved to Microsoft in 1981. Simonyi also hired Richard Brodie from PARC. On February 1, 1983, Word Multi-Tool development began. After being given a new name Microsoft Word, Microsoft published this program on October 25, 1983 for the IBM PC. At that time the word processing world is controlled by WordPerfect and also WordStar.

Word has the concept of "What You See Is What You Get", or WYSIWYG, and is the first program that can display bold and italic prints on the IBM PC. Word also used a lot of mice that were not so prevalent so they offer Word-with-Mouse packages. Other DOS-based Word processors, such as WordStar and WordPerfect, display text only with markup and color codes to mark bold, italic, and so on.

Word for Macintosh, despite having many different views of its DOS version, is programmed by Ken Shapiro with little difference from the DOS version source code, written for high-resolution display screens and laser printers, even though no such products are publicly circulated. After LisaWrite and MacWrite, Microsoft also tries to add the WYSIWYG feature into the Word for Macintosh programming package. After Word for Macintosh was released in 1985, the program gained considerable attention from the community of computer users. Microsoft does not create versions of Word 2.0 for Macintosh, to equate versions with Word for other systems or platforms.

The next version of Word for Macintosh, is Word 3.0, released in 1987. This version includes many enhancements and new features but has many bugs. In just a few months, Microsoft replaced Word 3.0 with Word 3.01, which is much more stable. All registered users of Word 3.0 are sent a letter containing a copy of Word 3.01 for free, making this the most expensive Microsoft error to redeem at that time. Word 4.0, released in 1989, is a very successful and also stable version used.

Year 1990-1995
In this year's range, Word for Windows launches. The first version of Word for Windows was released in 1989 at a price of 500 US Dollars. With the release of Microsoft Windows 3.0 in the next year, sales were finally boosted up, considering Word for Windows 1.0 is designed for Windows 3.0 and its performance is very bad if run on previous versions. Microsoft waited until the release of Word 2.0 to reinforce Microsoft Word as the leader of the word processing market.

Microsoft Word 2010
This version is the version that Microsoft releases for Office on Windows, with support For Windows 8, Windows 7, Windows Vista (With Service Pack 2), Microsoft Windows XP (Service Pack 3) (Launched In 2010) >Unnecessary feature feature removal in Microsft Office 2010, making it lighter. >Better Graphics Support Better >Support Standardization Open Document Format format (.odf) >Supports more complex image editing >Simpler .pdf and .xps file storage >Integrated with Windows Live so it can store data on Cloud Cloud >Provision of 32 bit and 64 bit versions >The Ribbon is simple and easy to use.

Microsoft SQL Server
Microsoft SQL Server is a relational database management system (RDBMS) of Microsoft products. The important query language is Transact-SQL which is an implementation of the standard SQL ANSI / ISO used by Microsoft and Sybase. SQL Server is used in the business world that has a small-scale database up to, then evolved with the use of SQL Server on large databases.

Microsoft SQL Server and Sybase / ASE can communicate over the network using the TDS (Tabular Data Stream) protocol. In addition, Microsoft SQL Server also supports ODBC (Open Database Connectivity), and has a JDBC driver for the Java process language. Another feature of SQL Server is its ability to create database mirroring and clustering. In previous versions, MS SQL Server 2000 was attacked by a SQL Slammer computer worm that crippled the Internet access on 25 January 2003.
