Wondering what is word processing software? The word processing software is a computer application that is used to create, modify, format and store textual documents. It enables you to compose letters, reports, essays or books using such tools as spell check, templates, headers/footers and tables. On top of mere editing, modern word processors also offer a high level of functionality such as style controls, real time collaboration (in applications such as Google Docs) or offline desktop publishing capabilities (as in the LibreOffice Writer). It is essentially a digitalized type writer, more powerful, flexible and user-friendly.
