Question 1

Big Data

Answer 1

: Large, complex datasets (can include images, text, numbers). Too large for a single computer to process quickly.

Question 2

Data Science

Answer 2

: The process of analyzing and manipulating large datasets to extract useful information.

Question 3

TinyDB

Answer 3

Stores data locally on the device.

Data access is synchronous (immediate).

Best for apps used by one person on one device.

Not shared between users/devices.

Question 4

CloudDB

Answer 4

Stores data online, in the cloud.

Data access is asynchronous (may take time)

Allows multiple users/devices to access shared data.

Requires an event handler like GotValue to detect when data is ready.

Question 5

Synchronous

Asynchronous

Answer 5

A-: Happens after a delay; program must wait for confirmation (CloudDB).
S-: Happens immediately (TinyDB).

Question 6

Algorithmic bias

Answer 6

Systematic errors caused by flawed data or biased algorithms.:
Can create unfair or discriminatory outcomes.

Often happens when:
Data isn’t diverse enough.
Data is collected unfairly.
The algorithm is trained on biased information.

Question 7

Open Access

Answer 7

: Data that’s publicly available to everyone.

Question 8

Unauthorized Access

Answer 8

: Using or copying someone’s data/work without permission = Piracy.

Question 9

Memory Units (Smallest to Largest)
Petabyte → Exabyte → Zettabyte → Yottabyte

Question 10

Decimal vs Binary Storage
Everyday/Decimal: 1 kilobyte = 1000 bytes
Computer/Binary: 1 kilobyte = 1024 bytes

Question 11

DMCA
Digital Millennium Copyright Act

Answer 11

Purpose: To prevent copyright violations with digital content and technology.

Question 12

Machine Learning

Answer 12

Computer learns from data (example: drawing activity where the computer guessed what you were drawing).

Question 13

🎵 Napster

Answer 13

A program where users downloaded songs from each other.

Example of peer-to-peer (P2P) architecture.

Shut down due to copyright infringement lawsuits.

Question 14

Data to Test Hypotheses

Answer 14

Create a visualization (e.g., charts, graphs) to identify trends or patterns.
Helps determine whether a hypothesis is supported or not.

Question 15

Copyright:

Answer 15

A legal right that gives the creator of original work control over how it’s used, shared, or reproduced.

Violating copyright = using someone else’s work without permission = piracy

Fair Use: Limited use of copyrighted material for things like education, criticism, news, or parody (with restrictions).

Best Practice: Always give credit and get permission if you’re using someone else’s content, especially in apps or websites.
