One of the most well known freeware office packages is Open Office. This is likely because it is an all encompassing suite that attempts to rival Microsoft Office in features. The main difference is that it represents itself as one item, rather than the way that Office Suite is broken up by specifically naming each program separately. This also allows for full spreadsheets, graphical support, the creation of presentations, and a tool for working on large databases. The program utilizes the International Open Standard Format, which allows the application to read files created in other programs.
