MS Office (Microsoft Office) is a productivity suite widely used in government offices, businesses, and education. For MPESB exams, questions focus on practical knowledge — identifying toolbar functions, keyboard shortcuts, file extensions, and basic operations in Word, Excel, PowerPoint, and Access.
Key ideas
- MS Word is a word processor for creating documents — letters, reports, resumes. Default extension is .docx (older format: .doc).
- MS Excel is a spreadsheet application for calculations, data analysis, and charts. Files are stored as .xlsx workbooks containing multiple worksheets.
- MS PowerPoint creates presentations with slides containing text, images, animations, and transitions. Default extension is .pptx.
- MS Access is a database management system (DBMS) for storing and querying structured data. Uses .accdb format and works with tables, queries, forms, and reports.
- Ribbon Interface — All modern MS Office apps use a ribbon (introduced in Office 2007) with tabs (Home, Insert, View, etc.) containing grouped commands.
