AP CSP - Vocab - 2.3 and 2.8

2.3 - What is an algorithm?

• An algorithm is a random guess to find a solution.
• An algorithm is a step-by-step procedures for solving a particular problem.

• An algorithm is a type of computer hardware.
• An algorithm is a collection of unrelated data.

2.3 - What is a control structure?

• A control structure is a graphical representation of code.
• A control structure is a block of programming statements that controls the flow or behavior of an algorithm.

• A control structure is a method for storing data.
• A control structure is a type of variable in programming.

2.3 - What is a sequence?

• A sequence control structure is the application of each step of an algorithm in the order in which the statements are given.

• A sequence is an unordered set of numbers.
• A sequence is a single element.
• A sequence is a random collection of items.

2.3 - What is selection?

• Selection is the act of discarding items from a set.
• Selection refers to the random arrangement of items.
• A selection is the process of duplicating items in a set.

• A selection control structure uses a true or false condition to determine which of two parts of an algorithm is used.

2.3 - What is repetition?

• Repetition is a form of meditation.
• A repetition control structure is the repetition of an algorithm for a specified number of times or until a true/false condition is met.

• A repetition is the process of forgetting something.

• Repetition is the act of creating something new.

2.3 - What is iteration?

• Iteration refers to the process of compiling programs.
• Iteration is a method for debugging code.
• Iteration is a technique for optimizing memory usage.
• Iteration is another term for 'repetition'.

2.3 - What is boolean?

• A Boolean condition is a true/false condition. It is named after George Boole (1815-1864) an English mathematician.

• A Boolean is a type of programming language.

• Boolean can have multiple values including numbers.
• Boolean is a data type that represents characters.

2.3 - What is pseudocode?

• Pseudocode is a programming language used for software development.
• Pseudocode is a blend of English and code used to write down an algorithm for a program.

• Pseudocode is a formal method of writing code in a specific programming language.
• Pseudocode is a type of algorithm that only works in Python.

2.3 - What is a flowchart?

• A flowchart is a type of computer program.
• A flowchart is a visual (i.e. graphical) notation for expressing algorithms.

• A flowchart is a written document outlining a project.
• A flowchart is a list of tasks to be completed.

2.8 - What is an abstraction?

• Abstraction is the process of creating complex systems without any simplification.
• Abstraction refers to the physical representation of objects in programming.
• An Abstraction is the act of detailing every aspect of a system without omission.

• An abstraction is a general representation of something -- of some person or place or event or process. An abstraction extracts common features from specific examples in order to generalize concepts. Words, symbols, maps, and models are all examples of everyday abstractions.
