Open-source Software: Apache OpenOffice
For those that don't have the money to buy, or the means to come by, Microsoft Office and all of its tools (Word, Excel, PowerPoint, etc.) there is a great open-source alternative that I have used for many years: Apache OpenOffice.
OpenOffice is just like Microsoft Office in most if not all aspects, as well as being available for multiple operating systems (Linux, OS X, and Windows.) AND IT'S FREE!!
The files save as an ODF (Open Document Format) which can be read by Microsoft Office programs, so moving files/documents from one Office suite to the other is almost seamless. Also, the file formats of Microsoft Office, such as .docx can be read on OpenOffice.
As an educator, free, open-source software is a great alternative/tool, especially with the low education budgets and cut-backs in today's economic situation.
