•  Typewriter does not have all the required characters or symbols. It is not possible to type all the characters using a
              typewriter.
            •  There is no concept of formatting a document using a typewriter.
            In 1974, Xerox (company) introduced an electronic typewriter which had the capability to resolve most of the give
            limitations of a manual typewriter. It has a small screen that shows one or two lines and provides the facility to make
            small changes to the existing content. It also helped in making multiple copies of the same document. Later on, with
            the development of computer and application software, the electronic typewriters were completely replaced by word
            processing software, thus marking the beginning of the computer era.



                    WORD PROCESSOR

            A word processor is an application software which is commonly used to create, edit, format, and print a document. It
            can help us to create letters, applications, resumes, articles, poems, booklets, advertisements, invitations, and many
            more things. It supports graphical user interface where the text of specific size, font, colour or any other formatting
            feature on the screen will exactly resembles the same as taken on the printing paper. This is called WYSIWYG feature
            (What You See Is What You Get).

            Features of Word Processor
            Some of the important features provide by any word processing program are summed up below:

            •  Easy Typing and Word Wrapping Feature: Text can be easily typed, edited, deleted and moved to the next line
              automatically in any word processor. When a line is finished, the text flows automatically on a new line. This is called
              Word Wrap. We use the Enter key in case we want to start a paragraph or end a short line or create a blank line.
              There is no word limit for any kind of document.
            •  Saved, Stored and Retrieved when Required: A document can be saved in the computer or any other storage device

              be easily done.
            •  Spelling and Grammar Check: The Autocorrect feature will take care of the spelling and grammar of the text. If
