Key Points at a Glance

  1. 1

    Official syllabus anchor: CET Graduation Computer Knowledge includes MS Office, specifically MS Word, MS Excel/spreadsheet and MS PowerPoint; this topic covers the Word and PowerPoint part of that block.

  2. 2

    Word file rule: `.docx` is the normal modern editable Word document format; `.docm` is used when a Word document contains macros; PDF is used when a stable sharing or printing copy is needed.

  3. 3

    Editing changes the document content; formatting changes how the same content looks. Use Styles for repeated headings and body text instead of manually changing every heading one by one.

  4. 4

    Page layout tools such as margins, orientation, columns, page breaks and section breaks control how the document is arranged on pages; section breaks can allow different layout settings in different parts of a document.

  5. 5

    Review tools have separate purposes: Track Changes records proposed edits until they are accepted or rejected, while comments add discussion notes without changing the final text by themselves.

  6. 6

    Mail merge combines a main document, a data source and merge fields to create personalized letters, emails, envelopes or labels; always preview records before final output.

  7. 7

    PowerPoint exam distinction: Slide Master controls common design, transitions apply between slides, animations apply to objects on a slide, Presenter View shows notes privately, and print/export choices depend on the audience purpose.

MS Word as a document processor

MS Word is a word-processing application used to create, edit, format, review, print and share documents. In the CET Graduation syllabus this sits inside Computer Knowledge under MS Office, so questions usually test practical recognition of commands and file choices rather than software history. Word is suitable for letters, applications, notices, reports, minutes, certificates, resumes, forms and other text-heavy office documents. It is more than a plain typing screen because it can handle layout, headings, tables, pictures, page numbers, headers, footers, proofing tools, review marks and multiple output formats.

The exam-relevant file-format distinction is simple. A normal modern editable Word document is saved as `.docx`. If a Word document contains macros, the macro-enabled format is `.docm`; this distinction matters because macros can automate work and can also create security risk if an unknown file is trusted blindly. Older `.doc` files may appear in offices, but for current MS Office questions `.docx` is the standard modern Word document format. PDF is different: it is chosen when the document must be shared, uploaded or printed with stable appearance, not when another person is expected to continue ordinary Word editing.

A strong answer always connects the tool with the task. Use Word when the main output is a structured document. Use the correct format according to the purpose: editable work in `.docx`, macro-enabled work in `.docm`, and fixed sharing or printing in PDF.
