Algorithm A precise sequence of instructions for processes that can be executed by a computer and are implemented using programming languages.
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.
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.
Turtle Programming a classic method for learning programming with commands to control movement and drawing of an on-screen robot called a "turtle".
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 a named group of programming instructions. Functions are reusable abstractions that reduce the complexity of writing and maintaining programs.
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.
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.
