Test 3 Flashcards
Impacts of technology on our lives
Can provide benefits but also downsides. We need to consider ethical and moral issues that may arise for example impact on business, industry, individuals, and the environment we live in
Impacts of AI
It is considered a threat to employment as advances in machine learning could lead to mass employment. AI is already involved in every aspect of our lives eg. they help make web transactions and fly planes.
Impacts of biometrics
Most obvious use is in passports where they have allowed the use of automated passport checks. Fingerprint scanners are also being used more often such as recording arrival and departure times in places of work
Impacts of virtual reality
Virtual reality currently is very impressive and is used for a lot of training purposes. It is very expensive but allows training that would otherwise be impossible eg. allows for pilots to practice emergency routines
Impacts of drones
They are already used in numerous industrious, from retail to manufacturing. It is still new technology however it has the potential to carry out courier roles which results in job losses but also demand for more skilled people managing an efficient drone network
Impact on the environment
Designing products to last has become increasingly important in the 21st century. Everyone wants the latest technology and designs eg an old vacuum cleaner with a bad can still work so why do people need new ones. As companies introduce new technologies, old products become obsolete and it becomes harder to have access to feature that can link it to a new digital system.
What is planned obsolesce
It is deliberately making an item out of date by stopping its supply or service by introducing a newer version or model. This is to encourage customers to upgrade. For example, washing machines are designed with planned obsolesce in mind meaning they only last a few years. After a couple years, vital parts begin to wear out, the company wont provide replacements and a new machine would be needed.
How to contribute to saving resources
Conserving energy where possible eg turning down heating or using a bike, using energy efficient devices eg refrigerators, washing machines, freezers, choosing reusable products over disposable ones
What is sustainability
It is meeting the needs of today without compromising the ability of future generations to meet their own needs
How to design sustainably
Manufacturing products with less energy, Making products fuel and material efficient, designing products to be longer lasting and better functioning so there is less replacement and use of products
What is a circular economy
The circular economy focuses on reducing waste and optimizing resource use by designing products for longevity, reuse, repair, refurbishment, and recycling, instead of the traditional “take, make, dispose” model.
What is cradle to cradle production
It is when all products are seen as either technical or biological nutrients. Technical nutrients can be recycled or reused with no loss of quality, and biological nutrients can be composted or consumed. Adidas and Parley made trainers with uppers made or recycled plastic from the ocean.
Why is the demand for energy increasing in countries
Developing countries emerge as rapidly growing industrial powers with plans for future expansion . Meeting these demands is concerning for the use of existing technologies to generate electricity.
How is energy stored and transferred
Kinetic energy - energy in a moving object. Dynamos and wind up energy transfer potential energy into kinetic energy
Thermal energy - energy that comes from heat. The sun, radiators and fires give off thermal heat
Chemical energy - chemical energies are available in different forms and are stored in fuels that we burn to release thermal energy. Batteries use chemical energy
What are non renewable resources
They are sources that come out of the ground as liquids and gases and solids and cannot be quickly replenished. Coal, Crude oil and natural gas are considered fossil fuels because they were formed from buried remains of plants and animals that lived millions years ago.
