Define desktop computer.
A desktop computer is a computer designed to stay in one place, for example on a desk.
Define mobile computer.
A mobile computer is a computer designed to be portable, for example a laptop.
Name the three separate parts a desktop computer traditionally consists of.
A desktop computer traditionally consists of a separate monitor, computer, and keyboard and mouse.
True or False?
Mobile computers are typically more powerful than desktop computers.
False.
Mobile computers are typically less powerful, because of power constraints due to size and a focus on extending battery life.
Why are desktop computers easier to upgrade than mobile computers?
Desktop computers are upgradable because their parts can be replaced or changed, whereas a mobile computer's components are integrated for size and efficiency.
Give two reasons a mobile computer is less powerful than a desktop.
A mobile computer is less powerful because of power constraints due to its size and a focus on extending battery life.
Unlike a desktop computer, a mobile computer is powered.
Unlike a desktop computer, a mobile computer is battery powered.
Give two characteristics of a smartphone.
A smartphone has a small physical size, is easy to carry around, has a long battery life and has slower data transfer rates.
How does a tablet differ from a smartphone?
A tablet has a larger screen than a smartphone and is ideal for media consumption and web browsing, but has limited expandability.
Give three advantages of a mobile computer.
Mobile computers offer portability, so they are easy to carry and use on the go; flexibility, giving access to the internet and resources from anywhere; and multi-functionality, so they can be used for many tasks.
Give three disadvantages of a mobile computer.
Mobile computers have limited expandability, are less powerful than desktop computers, and have a shorter battery life needing frequent charging.
Give two uses of a mobile computer for remotely controlled devices.
A mobile computer can be used for controlling smart home devices, remote access to surveillance systems, and controlling drones and other devices.
Define artificial intelligence.
Artificial intelligence (AI) is a machine that can simulate intelligent behaviours similar to those of a human.
Name the three things an AI system can do.
An AI system can learn, by acquiring new information; decide, by analysing and making choices; and act autonomously, by taking actions without human input.
Define weak AI.
Weak AI, also known as narrow AI, is designed to perform a specific task or set of tasks.
Define strong AI.
Strong AI, also known as artificial general intelligence (AGI), is designed to perform any intellectual task that a human can do.
True or False?
Narrow AI is another name for strong AI.
False.
Narrow AI is another name for weak AI, which performs only a specific task. Strong AI is also known as artificial general intelligence.
Give two advantages and two disadvantages of AI.
AI offers increased efficiency, increased accuracy and scalability, but it brings job losses, the potential for biased decision making and ethical concerns over its use.
Define extended reality.
Extended reality (XR) is an emerging technology that blends the virtual and real worlds together to create immersion for a user.
What are the two popular examples of extended reality?
The two popular examples of extended reality are virtual reality (VR) and augmented reality (AR).
How does virtual reality work?
Virtual reality shuts out the real world and immerses the user in a fully simulated environment, using a headset with built-in screens giving a 360 degree view.
How does augmented reality differ from virtual reality?
Augmented reality overlays digital information or graphics onto the real world, so the user is not fully immersed and can still see and interact with what is in front of them.
In virtual reality, users are often able to interact with the virtual world through tracking.
In virtual reality, users are often able to interact with the virtual world through motion tracking.
Give two fields outside gaming where XR is applied.
XR is applied in architecture, medicine and retail for improved visualisation and interaction, and in education and training for a more engaging experience.
