MICROSOFT WORD

Word processor is used to produce documents for business or personal

use such as newsletter, reports, letters and essays. We might say that a word

processor is an intelligent typewriter. We can type a whole page, make

corrections (editing), use up paragraphs in different styles and shapes and

columns (formatting) and also check spelling, find and insert synonyms for a

word (Thesaurus) and process it in many more ways before we actually put

that page to print.

FEATURES OF WORD PROCESSOR

The following are the main features of a word processor:

Fast

Editing features

Permanent storage

Formatting features

Graphics
