There are many advantages of using a word processor.
Some of these are:
If you want to add something extra or remove some text after getting your report checked by a teacher, you can easily do it in a word document.
When making a resume (bio-data), it is important not to make any spelling mistakes. A word processor helps you check spelling and grammar so that you use correct grammar, spelling and language.
If you are writing a long report and you need to work on it for several days, you can save the report and get back to it whenever required. You can also print the document if you have to send a hard copy to someone.
You can make the document attractive by adding different colours, text styles and text sizes. For example, if you want to write the title in a special style or if you want to highlight some important date, you can do it in a word document.
You can also make a poster using a word processor by inserting pictures, bulleted lists, tables, shapes and charts easily.
