Term | Definition |
---|---|
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. |
