• There is no saving of digital data, so a document which needs to be duplicated, has to be typed again.
• 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.
Electronic Typewriter
In 1974, Xerox (company) introduced an electronic typewriter which had the capability to resolve most of the
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
helps us 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
that is visible on the screen will exactly resemble the same as taken on the printing paper. This is called WYSIWYG
(What You See Is What You Get) feature.
Features of Word Processor
Some of the important features provided by any word processing software are as follows:
Header and Footer Mail Merge Word Wrap Column
Voice Recognition Printing AutoCorrect Tables
Spelling and
Formatting Thesaurus Find and Replace
Grammar
• 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, and can be easily sent and received through the Internet as an attachment.
• Select, Move, Copy and Delete the Text: A small portion or complete data can be easily selected and moved to
some other place in a document. In case the data needs to be repeated then by using the copy/paste option it can
be easily done.
