Social Implications Grade 11
The impact of technology on society — covering IoT, Big Data, the Fourth Industrial Revolution, cybercrime, and digital ethics.
Social implications are revisited every term rather than taught once. The sections below are grouped by the term where each topic is introduced on the Year Planner — but all of it stays examinable afterwards.
Digitalisation and the 4IR
| Effect | Positive | Negative |
|---|---|---|
| Employment | New IT-related jobs created | Many routine jobs automated away |
| Efficiency | Faster, more accurate processes | Over-reliance on technology |
| Access | Global connectivity and knowledge sharing | Digital divide widens |
| Privacy | Better security systems | Constant surveillance and data collection |
The Gig Economy
The gig economy is a labour market built on short-term, flexible jobs or "gigs" (freelance or on-demand work) rather than permanent employment, usually arranged through online platforms.
- Examples: Uber/Bolt drivers, Mr D and other food-delivery couriers, freelancers on Fiverr or Upwork.
- Advantages: flexible hours, work from anywhere, an easy source of extra income.
- Disadvantages: no job security, no benefits (paid leave, medical aid, pension), and an unpredictable income.
Blockchain
A distributed digital ledger where data is stored in linked, tamper-resistant "blocks".
- Decentralised — no single owner
- Highly secure — changing one block breaks the chain
- Used for: cryptocurrency (Bitcoin), smart contracts, supply chain tracking
Cybercrime
| Crime | Description |
|---|---|
| Identity theft | Stealing personal info to commit fraud |
| Business data theft | Stealing company secrets or customer databases |
| Ransomware | Encrypting company data and demanding ransom |
| SQL Injection | Inserting malicious SQL into web forms to access databases |
Internet of Things (IoT)
A network of physical devices embedded with sensors and internet connectivity that collect and exchange data automatically.
| Category | Examples |
|---|---|
| Smart home | Smart fridges, thermostats, security cameras |
| Connected cars | Real-time traffic, remote diagnostics |
| Healthcare | Remote patient monitoring, smart wearables |
| Agriculture | Soil sensors, weather monitoring for crop yields |
| Smart cities | Adaptive lighting, smart bins, traffic management |
Big Data
Extremely large and complex datasets that traditional software cannot handle. Characteristics: Volume, Velocity, Variety.
- Healthcare: track vitals, predict illnesses
- Marketing: personalised advertising
- Banking: fraud detection
- Risk: privacy erosion, data breaches, discrimination
Crowdsourcing
Crowdsourcing is getting ideas, content, services or funding by asking a large group of people (the "crowd"), usually online, rather than from traditional employees or suppliers. The internet makes it possible to reach huge numbers of contributors quickly.
| Type | Example |
|---|---|
| Crowdfunding (raising money) | Kickstarter, BackaBuddy, GoFundMe |
| Knowledge / content | Wikipedia, Stack Overflow, OpenStreetMap |
| Reviews & ratings | Google Maps reviews, TripAdvisor |
| Problem solving / micro-tasks | Citizen-science projects, design competitions |
Benefit: taps into a wide range of skills and ideas cheaply and quickly. Risk: contributions may be inaccurate, biased or unverified.
Privacy: Advantages & Disadvantages
Privacy is your right to control what personal information is collected about you and how it is used. Technology constantly gathers data — what you browse, buy, watch and where you go — which brings real convenience but also serious risks. In an exam you must be able to argue both sides.
| Advantages of data collection | Disadvantages / privacy risks |
|---|---|
| Personalised services and recommendations (Netflix, online shops) | Constant tracking and surveillance of your activity |
| Faster, more convenient use (saved details, auto-login) | Personal data sold to third parties without consent |
| Better security — fraud and identity-theft detection | Data breaches can expose millions of records |
| Relevant, targeted advertising | Profiling can lead to discrimination (insurance, jobs) |
| Services improved by analysing user behaviour | Loss of anonymity; stalking risk from location data |
Protecting Your Privacy
- Adjust privacy settings on social media and apps
- Limit the personal information you share online
- Review app permissions (location, camera, contacts)
- Use strong, unique passwords and 2FA
- Know your rights under POPIA — SA law protecting personal information
Digital Footprint
The trail of data you leave online. Active: data you intentionally share (posts, forms). Passive: data collected without your knowledge (cookies, browsing history).
Implications: affects reputation, privacy, can be used by employers or cybercriminals.
