What a Word Processor Is
Quick answer Define a word processor, separate it cleanly from a text editor, and learn how documents are created, saved, reopened and stored in different file formats.
A word processor is application software used to create, edit, format, store and print documents that are made mainly of text. Writing a leave application to your principal, preparing a science project report, designing a certificate or printing a set of address labels are all word-processing jobs. Widely used examples are Microsoft Word, LibreOffice Writer, Google Docs and WPS Writer. Because the document appears on screen almost exactly as it will appear on paper, such software is described as WYSIWYG (What You See Is What You Get).
Students very often confuse a word processor with a text editor. A text editor, such as Notepad on Windows or gedit on Linux, stores plain text only: the characters and the line breaks, and nothing else. It carries no information about font, size, colour, boldness, page margins, tables or pictures. A word processor stores formatted text: the same characters plus every formatting instruction, image, table and page setting attached to them. That is the distinction the examiner is testing, so answer in terms of formatting and layout, never in terms of one program being better than another.
Because of this difference, the two are used for different work. A text editor is preferred when the file must stay perfectly plain — writing HTML code, editing a configuration file, or making notes that any program can read. A word processor is preferred when the document has to look presentable when printed.
Working with a document follows four basic operations. Creating a new document opens a blank page, usually with a shortcut such as Ctrl + N; most word processors also offer ready-made templates for resumes, letters and reports so you do not start from nothing. Saving writes the document from the computer's RAM (Random Access Memory, which is volatile and loses its contents when power goes off) to permanent storage such as the hard disk or a pen drive. The first save asks you for a file name and a folder. Opening loads a saved document back from storage into memory so you can continue working, and closing removes it from the screen.
Note the difference between Save and Save As, which is a favourite short-answer question. Save updates the existing file with your latest changes and keeps the same name. Save As asks for a new name, a new folder or a new file format, and therefore creates a second copy while leaving the original file untouched. Use Save As when you want to keep both the old and the new version.
Documents can be stored in several file formats, each recognised by its extension — the letters after the dot in the file name. Which format is the default depends on the software you use. Microsoft Word normally saves as .docx (Office Open XML), while LibreOffice Writer normally saves as .odt (OpenDocument Text). .doc is the older Word format. .rtf, Rich Text Format, keeps basic formatting and is meant for exchanging files between different word processors. .txt is plain text and drops all formatting. .pdf, Portable Document Format, fixes the layout so the file looks identical on every device and is normally used for sharing or printing rather than for further editing. Most word processors can export a document to PDF directly.
- A word processor creates, edits, formats, stores and prints formatted documents; a text editor handles plain text only.
- WYSIWYG means the screen shows the document nearly as it will be printed.
- Save updates the same file; Save As creates a new copy with a new name, location or format.
- The extension identifies the format: .docx, .odt, .doc, .rtf, .txt, .pdf.
- Saving moves work from volatile RAM to permanent storage such as a disk or pen drive.
- PDF fixes the layout for sharing and printing; it is not the usual editing format.
