What is Binary?
A machine that can run a program, including computers, tablets, servers, routers, and smart sensors.
What is a Computing Device?

What is a Bit?
The series of connections between computing devices on a network starting with a sender and ending with a receiver.
What is a Path?
Any data that are sent from a program to a device.
What is Output?
A permanent variable; Can be used anywhere in your code
What is a Global Variable?
A search algorithm that starts at the middle of a sorted set of numbers and removes half of the data; this process repeats until the desired value is found or all elements have been eliminated.
What is a binary search?
Error from attempting to represent a number that is too large.
What is an Overflow Error?
An agreed-upon set of rules that specify the behavior of some system.
What is a Protocol?
Program statements run in order, from top to bottom.
What is Sequential Programming?

What is an Assignment Operator?
Returns the remainder of a division problem.
What is Modulus?
Data with values that change continuously, or smoothly, over time.
What is Analog Data?
A chunk of data sent over a network. Larger messages are divided into these that may arrive at the destination in order, out-of-order, or not at all.
What is a Packet?
Form of program documentation written into the program to be read by people and which do not affect how a program runs.
What is a Comment?
The symbol == represents what type of Operator?
What is a Comparison Operator?
Returns true when either expression is true and false otherwise.
What is OR Boolean Operator?
A process for creating a digital representation of analog data by measuring the analog data at regular intervals.
What is Sampling?
Can continue to function even in the event of individual component failures.
What is Fault Tolerant?
Finding and fixing problems in an algorithm or program.
What is Debugging?
A named group of programming instructions. Also referred to as a 'procedure'
What is a Function?
An ordered sequence of characters.
What is a String?
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.
What is Intellectual Property?
The protocol used for transmitting web pages over the Internet
What is HyperText Transfer Protocol?
This occurs when the ending condition will never evaluate to true.
What is an Infinite loop?
Affects the sequential flow of control by executing different statements based on the value of a Boolean expression.
What is a conditional? (If statement)
The system responsible for translating domain names into IP addresses.
What is Domain Name System (DNS)?
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.
What are Creative Commons?

What is a Digital Divide?
The process of accessing each item in a list one at a time.
What is a traversal?
A bug in a program that causes it to operate incorrectly, but not to terminate.
What is a Logical Error?
Provides a "good enough" solution to a problem when an actual solution is impractical or impossible.
What is a Heuristic?
