Binary and Bits
This is the smallest unit of data in a computer, representing either a 0 or a 1.
Bit
Shrinking a file by throwing away data you won't notice is gone.
Lossy
The process of blacking out or removing sensitive info from a dataset.
Redaction
Huge, complex data sets that need special tools to process.
Big Data
This is a simplified version of something complex, like using a dot on a map to represent a city.
Abstraction
How many bits are in a single Byte?
8 Bits
Shrinking a file without losing a single piece of original info.
Lossless
"Data about data" (like the time a text message was sent).
Metadata
The gap between people with high-speed internet and those without.
Digital Divide
The process of keeping only the rows of data that meet a certain criteria.
An error that happens when a number is too big for the computer to hold.
Overflow Error
This file type is a classic example of Lossless compression.
1 example can be .ZIP others may be possible
A computer model used to predict what might happen in the future.
Simulation
Personal info like your SSN or address (abbreviated as PII).
PII (Personally Identifiable Information)
Removing data like duplicates or incomplete entries before use.
Data Cleaning
The highest number you can make with 4 bits.
15
This common file type uses Lossy compression to shrink photos.
The process of transforming raw data into a visual like a chart.
Data Visualization
A copyright license that lets others use your work for free.
Creative Commons
A collection of related data that is stored in a structured way (like a table).
Dataset
If a 3-bit system can hold 8 values, how many values can a 4-bit system hold?
16
A "good enough" solution used when the perfect one takes too long.
When a computer makes unfair decisions because the data was biased.
Algorithm Bias (In Schram)
The trail of data you leave behind every time you go online.
Digital Footprint
The process of taking a set of values and grouping them into categories.
