#AP Computer Science Principles: Big Idea 5 - Impact of Computing 🚀

Hey! Let's get you prepped for the AP Exam with a deep dive into Big Idea 5: The Impact of Computing. This section is all about how technology affects society, and it's a BIG part of your exam (21-26%). Think of it as the 'real-world consequences' of all that code we've been writing. Let's jump in!

#The Big Picture: Societal Impact 🌍

This big idea is all about the societal impact of computing. It's not just about the code; it's about how that code changes the world. We'll look at the good, the bad, and the unexpected.

#5.1 Beneficial and Harmful Effects

Learning Objective: Explain how a computing innovation can have both beneficial and harmful effects.

Learning Objective: Explain how a computing innovation can have an impact beyond its intended purpose.

• Societal Changes: How do we adapt to new tech? Think about how smartphones have changed daily life.
• Differing Opinions: Not everyone agrees on whether a tech is good or bad. Self-driving cars, for example.
• Unforeseen Consequences: Sometimes, tech does things we never expected. Social media was meant to connect people, but it also has downsides.
• Cross-Purpose: Tech made for one thing ends up being used for another. GPS was for the military, now it's in our phones.

Examples:

• Benefits: Increased communication, access to information, medical advancements.
• Harms: Job displacement, privacy concerns, spread of misinformation.

Vocabulary:

• World Wide Web: The system of linked hypertext documents accessed via the Internet.
• Targeted Advertising: Ads tailored to specific users based on their data.
• Machine Learning: Algorithms that learn from data without explicit programming.
• Data Mining: Discovering patterns in large datasets.
