B. Components of Office Automation
Five Core Components
The key tools that make up a modern automated office
| Component | What it Does | Software Examples |
|---|---|---|
| Word Processing | Creating, editing, formatting, and printing text documents. Replaced the typewriter. Features: spell check, templates, mail merge, headers/footers. | MS Word, Google Docs, LibreOffice Writer |

D. Benefits of Office Automation
Advantages & Disadvantages
What OA improves and what it costs
| Advantage | Explanation |
|---|---|
| Speed | Tasks completed much faster than manual methods. A mail merge can send 1,000 personalised letters in seconds. |
| Accuracy | Eliminates human calculation errors. Spreadsheet formulas are always correct if data is correct. |
| Storage | Massive amounts of data stored digitally on hard drives — no physical filing cabinets needed. |
| Cost Saving | Reduces paper, printing, and postage costs. Reduces need for large clerical staff. |
| Communication | Email and video conferencing enable instant worldwide communication. |
| Accessibility | Cloud-based systems allow access from anywhere, any time, on any device. |
| Security | Digital files can be password-protected, encrypted, and backed up — safer than paper. |
| Disadvantage | Explanation |
|---|---|
| High initial cost | Purchasing hardware and software requires significant upfront investment. |
| Training needed | Staff must be trained to use new systems — takes time and money. |
| Technical failures | System crashes, power cuts, or hardware failures can halt all work. |
| Security risks | Digital systems are vulnerable to hacking, viruses, and data breaches. |
| Job displacement | Some manual jobs become unnecessary — can lead to unemployment. |
Advantages
