Computer Science
A programmable device that stores, retrieves, and processes data; an electronic machine or device that performs processes, calculations and operations based on instructions provided by a software program.
What is a computer?
The ability to break a larger problem down into smaller parts.
What is decomposition?
Something that includes a program as an integral part of its function; it can be physical (e.g., self driving car), nonphysical computing software (e.g., picture editing software), or a nonphysical computing concept (e.g., e-commerce).

Any object in a game that has properties (i.e. position, velocity) and behaviors (i.e. it can move, it has effects).
What is a sprite?
Set of instructions or commands that tell the computer what to do.
What is Software?
Part of the computer that processes data and allows the computer to "think." Sometimes referred to as a "computer chip".
What is a Central Processing Unit? (CPU)

The four ideas of computational thinking
What are
Decomposition
Pattern recognition
Abstraction
Algorithmic thinking
A collection of computer commands that perform a specific task when run by a computer; often referred to as software.
What is a program?
An occurrence; things that happen, usually associated with an action (i.e. mouse click, button pressed).
What is an Event?
The physical parts of the computer.
What is Hardware?
How a computer stores data.
What is memory?
When you observe similarities and patterns within problems.
What is Pattern Recognition?
An abstraction inside a program that can hold a value. It has associated data storage that represents one value at a time, but it can be a list or other collection that in turn contains multiple values.
What is a variable?
DJ!
A group of programming statements that is part of a program.
What is a code segment?
DJ! *This question will have 2 answers*
Any part of a computer that can take information from the outside world and input it into the computer (i.e. keyboard, mouse, camera).
Parts of a computer that can output information to the outside world (i.e. display screen, printer, speakers).
What is input?
What is output?
DJ!
Short-term memory that computers use to cache temporary data that they can access quickly; data that gets constantly deleted or over-written.
What is Random Access Memory?
When you identify what defines the patterns you see, focus on the important information, and derive general rules and concepts that can be applied in other areas (carving out the relevant from the irrelevant).
What is Abstraction?
DJ!
a finite set of instructions that accomplish a specific task.
**DJ! Two Answers**
Data sent to a computer for processing by a program; it can come in a variety of forms, such as tactile, audio, visual, or text inputs.
Any data sent from a program to a device; can come in a variety of forms, such as tactile, audio, visual, or text.
What is program input and outputs?
Low-level software that interacts directly with the computer hardware, often called Operating System (OS) software (i.e. Windows, MacOS, Linux).
What is system software?
Long-term memory that computers use to store data files or other more permanent pieces of information that a user would expect to be able to access consistently.
What is storage?
DJ!
When you develop a step-by-step plan, or the rules to follow, to solve a problem.
What is Algorithmic Thinking?
How a program functions during execution; often described by how a user interacts with it.
What is behavior?
A part of code that 'handles' or listens for a specific type of event; when that event occurs, the code inside the event handler is run.
What is Event Handler?
Higher-level software usually specialized to do a particular task (i.e. Minecraft, Microsoft Word, banking website).
What is Application software?
