TermDefinition
Algorithm A precise sequence of instructions for processes that can be executed by a computer and are implemented using programming languages. (NOTE: this is the definition from the AP CS Principles framework).
Low level programming language A programming language that captures only the most primitive operations available to a machine. Anything that a computer can do can be represented with combinations of low level commands.
High level programming language A programming language with many commands and features designed to make common tasks easier to program. Any high level functionality is encapsulated as combinations of low level commands.
Algorithm A precise sequence of instructions for processes that can be executed by a computer
Iterate To repeat in order to achieve, or get closer to, a desired goal.
Selection A generic term for a type of programming statement (usually an if-statement) that uses a Boolean condition to determine, or select, whether or not to run a certain block of statements.
Sequencing Putting commands in correct order so computers can read the commands.
Abstraction a simplified representation of something more complex. Abstractions allow you to hide details to help you manage complexity, focus on relevant concepts, and reason about problems at a higher level.
Function named group of programming instructions. Functions are reusable abstractions that reduce the complexity of writing and maintaining programs New Blocks
Top Down Design a problem solving approach (also known as stepwise design) in which you break down a system to gain insight into the sub-systems that make it up.
API a collection of commands made available to a programmer
Documentation a description of the behavior of a command, function, library, API, etc.
Hexadecimal A base-16 number system that uses sixteen distinct symbols 0-9 and A-F to represent numbers from 0 to 15.
Library a collection of commands / functions, typically with a shared purpose
Parameter An extra piece of information that you pass to the function to customize it for a specific need.
Loop a programming construct that repeats a group of commands.
Iteration "loop" by another name - the repetition of a statement, process, or procedure.
For Loop A particular kind of looping construct provided in many languages. Typically, a for loop defines a counting variable that is checked and incremented on each iteration in order to loop a specific number of times.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
