Step 2
Step 3
Explain why it is important for computing technology to be inclusive.
Answer
Inclusivity in computing technology is important because it helps to bridge the digital divide, ensuring that all individuals, regardless of their background, have access to technology. This accessibility promotes equity in society, as it allows more people to benefit from advancements in technology and can lead to legal requirements and increased sales for businesses.
Step 4
Explain one positive impact of computing technology on the environment.
Answer
One positive impact of computing technology is its ability to enhance efficiency in resource management. For instance, technology can optimize energy use in smart grids, which reduces wastage and lowers the carbon footprint.
Step 5
Describe one freedom that open source software provides to developers.
Answer
Open source software provides developers the freedom to modify and distribute the software as they see fit. This means that developers can adapt the software for their specific needs or innovate upon it without any restrictions.
Step 6
Describe how abstraction could be applied to playing cards when creating a card game to run on a computer.
Answer
Abstraction allows programmers to manage complexity by simplifying the interaction with playing cards. Instead of focusing on the details of each card, a programmer can represent each card as an object in code, encapsulating attributes (like suit and value) and behaviors (like shuffle and deal). This enables easier management of the card game's functionalities without needing to handle the low-level details of each card.
