 office suite





An office suite is a set of applications designed to work with electronic documents on a computer.

Even if your direct work is not related to electronic documents, you will still encounter them, since most information in electronic form is presented in the format of office documents (text and tabular data). Thus, even just to open such documents, you will need special programs, and all such programs are just in the office suite. In other words, using a computer without office applications will become, if not difficult, then certainly inconvenient.

By default, Windows 10 does not include any office applications, so the office suite is a very useful and necessary program for Windows 10.

The most popular office suite for Windows is, of course, Microsoft Office. LibreOffice is a free alternative.

In addition to text and spreadsheet office documents, I also include PDF documents in this category, so in addition to the office suite, you definitely need a program for viewing PDF files.
