OpenOffice is an open source and free office software. Microsoft Office is the same as Microsoft Office, but OpenOffice is a free version of Microsoft Office. OpenOffice is written in C ++ and Java programming languages.
OpenOffice includes word processing (Writer), spreadsheet (Calc), presentation app (Impress), image app (Draw), formula editor (Math), and database management application (Base Management).

It can also read various other file formats, with special attention from Microsoft Office.

OpenOffice.org is mainly developed for Linux, Microsoft Windows and Solaris, and later for OS X, with ports to other operating systems. It is distributed under the GNU Lesser General Public License version 3 (LGPL). Initial versions are also available under Sun Industry Standards Source License (SISSL).

• Great software
  Apache OpenOffice is the result of over twenty years' software engineering. Designed from the start as a single piece of software, it has a consistency other products cannot match. A completely open development process means that anyone can report bugs, request new features, or enhance the software. The result: Apache OpenOffice does everything you want your office software to do, the way you want it to.
  
• Easy to use
  Apache OpenOffice is easy to learn, and if you're already using another office software package, you'll take to OpenOffice straight away. Our world-wide native-language community means that OpenOffice is probably available and supported in your own language. And if you already have files from another office package - OpenOffice will probably read them with no difficulty.
  
• and it's free
  Best of all, Apache OpenOffice can be downloaded and used entirely free of any license fees. Like all Apache Software Foundation software, Apache OpenOffice is free to use. Apache OpenOffice is released under the Apache 2.0 License. This means you may use it for any purpose - domestic, commercial, educational, public administration. You may install it on as many computers as you like. You may make copies and give them away to family, friends, students, employees - anyone you like.
