Unit 1 - Digital Information
Unit Vocabulary
Binary: A way of representing information using only two options.
Bit: A contraction of "Binary Digit"; the single unit of information in a computer, typically represented as a 0 or 1
Byte: 8 bits
Overflow Error: Error from attempting to represent a number that is too large.
Round-off Error: Error from attempting to represent a number that is too precise. The value is rounded.
Analog Data: Data with values that change continuously, or smoothly, over time. Some examples of analog data include music, colors of a painting, or position of a sprinter during a race.
Digital Data: Data that changes discretely through a finite set of possible values
Sampling: A process for creating a digital representation of analog data by measuring the analog data at regular intervals called samples.
Lossless Compression: A process for reducing the number of bits needed to represent something without losing any information. This process is reversible.
Lossy Compression: A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This process is not reversible.
Intellectual Property: A work or invention that is the result of creativity, such as a piece of writing or a design, to which one has rights and for which one may apply for a patent, copyright, trademark, etc.
Creative Commons: A collection of public copyright licenses that enable the free distribution of an otherwise copyrighted work, used when an author wants to give people the right to share, use, and build upon a work that they have created

Unit 4 - Variables, Conditionals, and Functions
Unit Vocabulary
Expression: a combination of operators and values that evaluates to a single value
Assignment Operator: allows a program to change the value represented by a variable
Variable: a named reference to a value that can be used repeatedly throughout a program.
String: an ordered sequence of characters.
Boolean Value: a data type that is either true or false.
Comparison Operators:
Logical operator: NOT, AND, and OR, which evaluate to a Boolean value.
Conditional Statement: affect the sequential flow of control by executing different statements based on the value of a Boolean expression.
Function: a named group of programming instructions. Also referred to as a “procedure”.
Function Call: a command that executes the code within a function
