Topic 5
Cloud-based business applications
Cloud computing delivers computing resources — servers, storage, software — over the internet on a pay-as-you-use basis.
| Service model | What the provider supplies | Examples |
|---|---|---|
| SaaS (software as a service) | Ready-to-use applications | Microsoft 365, Google Workspace, Zoho Books, Salesforce |
| PaaS (platform as a service) | Platform to build and run apps | Google App Engine, Azure App Service |
| IaaS (infrastructure as a service) | Virtual servers, storage, networks | AWS EC2, Microsoft Azure VMs |
- Deployment models: public, private, hybrid and community cloud.
- Benefits: low upfront cost, scalability, anywhere access, automatic updates, collaboration. Risks: dependence on internet, data privacy, vendor lock-in.
Topic 6
Professional documents and reports in Word
- Create, save and print: File → New; Ctrl + S to save (.docx); Ctrl + P to print with print preview.
- Character formatting: font, size, bold (Ctrl + B), italic (Ctrl + I), underline (Ctrl + U), colour.
- Paragraph formatting: alignment (left, centre, right, justify), indents (left, right, first-line, hanging), line spacing.
- Lists: bullets and numbering.
- Headers and footers: text shown on every page — company name, page numbers, date.
- Page setup: margins, orientation (portrait/landscape) and paper size.
- Reports: use built-in heading styles, automatic table of contents, captions, footnotes, page numbers and section breaks; export to PDF for sharing.
Topic 7
Presentations in PowerPoint
- Start with a layout (title slide, title and content) and a design theme.
- Add text, pictures, charts, tables and SmartArt.
- Slide sorter view shows thumbnails of all slides to rearrange them.
- Slide show (F5) presents slides full-screen.
- Animations move objects on a slide; transitions are effects between slides.
