Word Processor

Imagine if there are no word processors in the world, chances are the publication of books would be as hard as it was hundreds of years ago. In the earlier days of word processors, people invented them only for the purpose of editing texts. If there was something misprinted in a book, the book had to be printed again. Also, back then there was no spell checker, and when people made a copy of a book it was so easy for people to make a lot mistakes in spelling. Finally, because of no spell checker, people had to double check a book before it was printed, and it took much time and energy as well. Today, word processors have more functions than before, and without word processors, writers might not be able to publish their books as easily as possibly.
