Word processing describes the process of creating or editing a document using a word processor, such as Microsoft Word or OpenOffice Writer. For example, with a word processor, a student could create a book report and then print it, save it to a disk, display it on the screen, or send it over e-mail. Also, a person looking for a job could create a résumé using a word processor, then email or print and mail it to job recruiters.
Before computers people used typewriters to write reports or other documents, which had nowhere near the capabilities as today's word processors. With a word processor, you can easily edit and make changes to a document, move text around in a document, add images, change fonts, check for spelling errors, and much more.
