In office productivity software, what do you call a program that helps you create written documents such as letters and reports and lets you go back to edit or correct the text as necessary?

Introduction / Context:
This question covers fundamental application software categories. In everyday computing, people use different programs for text documents, calculations and presentations. Each category has a specific name. Here the focus is on software used to create and edit written documents, which is an essential part of office work and education.

Given Data / Assumptions:

• The program helps create written documents such as letters, reports or essays.
• The user can return to the document and make corrections or changes later.
• The context is clearly typical office productivity software.
• Options include spreadsheet, personal writer, word printer, word processor and presentation editor.

Concept / Approach:
A word processor is a software application that allows users to enter, edit, format and print text based documents. Examples include Microsoft Word, LibreOffice Writer and Google Docs. Spreadsheets such as Microsoft Excel focus on numerical data and calculations. Presentation programs such as PowerPoint are used for slides. The terms personal writer and word printer are not standard names for a software category in textbooks.

Step-by-Step Solution:
Step 1: Identify the primary features described. The program creates written documents and lets you edit them later. Step 2: These features match what users do in Microsoft Word or similar applications, which are word processors. Step 3: A spreadsheet application is mainly used for rows and columns of numbers, formulas and charts, not for long paragraphs of text. Step 4: A presentation editor is optimised for slide based visual content and is different from a document editor. Step 5: Personal writer and word printer sound like generic labels and are not recognised software categories in exam material. Step 6: Therefore, the correct term for this type of program is word processor.

Verification / Alternative check:
If you look at any basic computer literacy book, you will find sections with titles like word processing, spreadsheet software and presentation graphics. In the word processing chapter, the description explains that a word processor is used to create, edit, format and print documents. Examples given match exactly the tasks in the question. This confirms that word processor is the correct answer and not any of the other option texts.

Why Other Options Are Wrong:
Spreadsheets are designed around cells, formulas and computations, not primarily text document creation. Personal writer and word printer are not established product categories, so selecting them would not align with standard terminology. Presentation editors are used to design slides for talks and lectures, not general textual documents. Only word processor clearly fits the description given.

Common Pitfalls:
Students occasionally confuse the names of specific programs with generic category names, for example thinking that Microsoft Word is the category name itself. Remember that Word is a word processor, Excel is a spreadsheet and PowerPoint is a presentation program. Knowing the generic names will help you answer many exam questions correctly.

Final Answer:
A program used to create and edit written documents is called a word processor.
