Microsoft has long been one of the giants of the Internet, but the prices of its licenses are causing a lot of the market to move to open-source software.
Word, the quintessential word processing software, has an uncertain future faced with free competitors such as LibreOffice or OpenOffice. These programs are not just text editors, but actually have the full range of functions of Microsoft Office, including word processing, spreadsheets, presentations and designs.
These two software packages are very useful for those who always work on the same computer all day long. But for those who change between computers throughout the day, the best option is Google Drive. Even though it is quite a basic version of the Office package, it eliminates problems encountered while traveling or if your device is lost or stolen, and it allows several people to work on the same document simultaneously. In addition they are compatible with all computers and operating systems (online platforms).
Somewhat less well known but considerably more useful than Google Drive files are Zoho Docs, a full suite of rather intuitive Office programs, with up to 5 gb of free online is storage.
