Social Implications Grade 12
How Big Data, data warehousing, globalisation and the 4IR affect society — privacy, employment, social media and the evolution of the web.
Social Implications of Big Data & Data Mining
Big Data is the term for datasets so enormous, fast-moving and varied that ordinary database tools cannot store or process them — think of every Facebook post, every WhatsApp message and every e-toll swipe in the country, all at once. When companies and governments mine this Big Data, the results affect real people's lives, and that brings both wonderful benefits and serious dangers.
Why Should We Care?
The same data that lets a hospital predict and prevent illness can also let an insurance company refuse you cover because your shopping habits suggest you eat unhealthily. The technology is neutral — it is how the data is used that creates the social problem. As IT students you must be able to argue both sides.
| Positive | Negative |
|---|---|
| Healthcare: predict and prevent illness | Privacy erosion — habits tracked without full consent |
| Fraud detection in banking | Discrimination based on data profiles |
| Personalised education programmes | Security breaches expose millions of records |
| Better government services | Data sold to third parties without user knowledge |
Globalisation and the 4IR
| Aspect | Effect |
|---|---|
| Globalisation | World interconnected economically and culturally; faster trade; outsourcing; cultural exchange; increased competition |
| 4IR technologies | AI, machine learning, IoT, robotics, automation, biotechnology, AR/VR, Big Data |
| Jobs | Routine jobs replaced by machines; new careers in data science, AI, cybersecurity |
| Workers | Must reskill constantly; digital literacy essential |
Computer Management (Gr 12)
Key factors affecting computer performance and maintenance:
- Software: outdated software causes security risks and slower performance
- Security: antivirus, firewall, strong passwords
- Housekeeping: disk cleanup, defragmentation, archiving, compression
- Hard drive space: insufficient space causes performance issues (virtual memory relies on it)
- Corrupt files: use SMART scan / Disk Check to detect and fix errors
Evolution of Social Media and its Effects
- Information overload: constant exposure to content makes it hard to focus or verify facts
- Personal data exposure: users voluntarily share location, habits, preferences
- Social engineering: attackers use social platforms to manipulate users into revealing information
- Wikis: collaborative knowledge (e.g. Wikipedia) — useful but reliability varies
- Cultural effects: global connectivity promotes exchange but can dilute local traditions
Privacy and Information Sharing
| Concept | Privacy implication |
|---|---|
| Cookies | Track browsing behaviour; can be used for targeted advertising |
| Anonymity | Enables free expression; also enables cyberbullying and illegal activity |
| GUIDs | Global Unique Identifiers track behaviour across websites and apps |
| Location data | Apps continuously track movement; risk of stalking and profiling |
| File sharing | Piracy is illegal and harms creators; but sharing also enables legal distribution |
Protecting Your Online Identity
- Use strong, unique passwords for every account
- Enable Two-Factor Authentication (2FA)
- Avoid posting sensitive personal information publicly
- Verify links before clicking — beware of phishing
- Keep software and antivirus updated
- Only connect to trusted Wi-Fi networks
- Periodically search your own name to see your digital footprint
