Uses of word processor –

Computer programs used to write and modify documents, the word processor creates the layout of the text, and previews on the computer monitor how the printed copy will appear. The ultimate ability is known as “what you see is what you get” (WYSIWYG; pronounced wi-zē-wig).

Word processors facilitate writing and editing, especially their ability to copy and move text (“cut-and-paste”), with their built-in dictionaries to check spelling, and their grammar checkers. Other common features include a wide choice of typographic fonts and sizes, different paragraph and page layouts, tools for finding and replacing strings of characters, and word count. Modern word processors have many of the features once reserved for desktop publishing systems, such as table creation and the import of graphic images. They typically provide templates for common document types, such as letters, memos and resumes, and can generate multiple copies of a document with recipient addresses drawn from a list (“mail merge”).
