IEB IT theory grade 12 LU5 summary (social economic implications)

Green computing
 What is green computing?
- the study of designing, engineering, manufacturing, using, and disposing of
computing devices in a way that reduces their environmental impact
 Four aspects of green computing
- green use: minimalize electricity consumption in electronic devices
- green disposal: repurposing, disposing correctly, or recycling electronic
equipment
- green design: designing energy-efficient electronic devices
- green manufacturing: reducing waste and environmental impact of manufacturing
devices
 ways to make computer usage greener
- use sleep mode to save power
- dispose of electronic devices correctly
- upgrade existing devices instead of buying a new one
Positive and negative environmental impact of technology
Advantages
 working electronically means less printing and less paper = less deforestation
 working at home and online conferences = less traveling and less pollution
 home working means reduction of office space, equipment, and travel costs
disadvantages
 technology consumes energy and are made with hazardous materials
 manufacturing requires oil that can pollute soil and water
 paper consumption is increased due to printing
 duping of old technology and no proper recycling

solutions to issues of global importance
artificial intelligence
 what can machine learning help solve?
- medical research by processing huge data amounts
- self driving cars reduce accidents
- tracking wildlife to prevent extinction
- predicting natural disasters
Pros of AI Cons of AI
Less room for errors High development cost
Improved efficiency Unemployment
Takes risks instead of humans Humans are machine dependant
Always available Lacks unique out of box thinking
Fast decision making Could dominate humans


Education
 smart classroom technology
- wireless tech, online lessons, cloud storage
- students and teachers can access a variety of resources
- self teaching using the internet
Virtual reality

,  VR technology can be used for training workers who need hands on experience
- medicine and engineering
Poverty
 Tech can create more jobs, reducing poverty
 Can create more opportunities for people to economically support themselves
Smart cities
 More efficient buildings and streets
- sensors can decrease water and electricity consumption
Transport
 Electric cars are more efficient
- efficient batteries and battery charging
 Sensors on roads
- monitor parking and traffic to reduce congestion
 Self-driving cars
- people can be productive while driving
- helps reduce pollution emitted (less acceleration and braking)
Public safety
 Location-based emergency communications increase public safety
Healthcare
 EMRs – electronic medical records
- doctors have access to medical history anywhere
 Blockchain technology
- helps issues of security, scalability, and privacy in healthcare sector
 Internet of things (IoT) wearables provides user-generated health data
- used to detect health issues early so they can be fixed
Disaster relief
 Tech has new effective ways to cope with the results of a natural disaster
- emergency services can save time and gain information easily
 Drones can drop of packages
 Mobile applications can contact emergency services
Farming
 Smart farming
- livestock monitoring, equipment testing, soil, and weather measurements
- increases productivity
Locate missing people
 Solve crimes and locate victims of human trafficking by tracking cyber activity

Effects of digital communication
 Mobile tech can decrease human communication and reduce privacy
Personal info
 Data misuse
- when data is used for a different purpose than the original reason it was collected
- it may not be clear what data is being collected or how it is used
Right to privacy
People have the right to privacy
- if a post is made on social media, privacy is no longer a right
