Study Notes

Changing Digital Technologies

Robotics includes industrial and autonomous robots that perform specific tasks and make their own decisions, respectively.
The impact of robotics on society, culture, and the economy includes loss of low-skilled jobs, more leisure time, consistent work standards, 24/7 work, and expensive installation and maintenance.
Autonomous cars capture data using RADAR, GPS, and sensors and have advantages such as fewer accidents, lower insurance costs, and improved accessibility, but also disadvantages such as job losses and potential software malfunctions.
Virtual reality is an application that imitates real-life situations and is being used in education to make lessons more immersive, boost creativity, and make boring topics interesting, but also has disadvantages such as privacy concerns and health and safety issues.
Augmented reality is a system that overlays information about the world onto a screen and is used in navigation, sports analysis, and surgery, but also has disadvantages such as privacy and security concerns and the potential for dangerous behavior.
Artificial intelligence includes machine learning and neural networks that perform tasks that require human intelligence and is being used in various industries such as retail, healthcare, finance, sales and marketing to improve efficiency and save costs, but also has disadvantages such as high production costs and unemployment.
The Internet of Things refers to devices connected to the internet that collect and share data with each other and data management systems, and includes digital assistants, smart lightbulbs, thermostats, doorbells, and locks, and can improve efficiency and save costs, but also has concerns about data privacy and security and vulnerability to cyberattacks.
Smart homes are a good example of the Internet of Things and include devices such as smart air conditioning, lighting control systems, thermostats, security systems, garage door openers, smart door locks, and smart meters.
ChatGPT is an AI chatbot that uses language-based models to interact with humans in conversations, gathers data from the internet, and learns more about different subjects and how to discuss them.
Changing digital technologies have positive impacts such as improved efficiency, saved costs, and immersive experiences but also have negative impacts such as job losses, privacy concerns, and potential dangers.
Changing digital technologies are being used in various industries such as education, healthcare, finance, sales and marketing, and manufacturing to improve efficiency, save costs, and provide better experiences.
Changing digital technologies require regular maintenance and support, which can be costly and time-consuming, and are vulnerable to cyberattacks, compromising data and systems.
