Word ProcessingWord Processing

A word processor enables you to create a document, store it electronically on a disk, display it on a screen, modify it by entering commands and characters from the keyboard, and print it on a printer.The great advantage of word processing over a typewriter is that you can make changes without retyping the entire document. Word processors also make it easy to move sections of text from one place to another within a document or between documents.

You can think of a database as an electronic filing system.Traditional databases are organized by fields, records, and files. A field is a single piece of information, a record is one complete set of fields, and a file is a collection of records. To access information from a database, you need a database management system (DBMS). This is a collection of programs that enables you to enter, organize, and select data in a database.
