Computer Science Final Review

Front 1

What does the method Stop () do?

Back 1

Stop the program

Front 2

Why does the order in which a programmer lists calls to methods matter?

Back 2

The order in which a programmer lists calls is the order in which they are executed by the computer. One command must finish running before the next one begins. If commands are listed in a different order, you might try to use a variable before it is defined or given an initial value.

Front 3

IDE

Back 3

Short for Integrated Development Environment; a complete programming environment that one uses to create programs

Front 4

List typical programming elements.

Back 4

1) Variables
2) If-then decisions
3) Loops
4) Methods
5) Functions

Front 5

What does XP mean?

Back 5

Extreme programming

Front 6

Sprite

Back 6

A graphical object that is defined by a two- (or three-) dimensional image or animation and integrated into a larger scene

Front 7

Sequencing

Back 7

The order in which a programmer lists calls to methods (example: top to bottom)

Front 8

Iteration

Back 8

The programming idea of repetition (example: loops)

Front 9

What is the programming construct that often describes iteration?

Back 9

A loop

Front 10

What is the repeated action performed in a loop often called?

Back 10

The body

Front 11

Selection

Back 11

The programming idea of the computer choosing between two alternative actions (example: if-then statements)

Front 12

Static

Back 12

Not moving

Front 13

Boolean

Back 13

A value that is either True or False

Front 14

Code

Back 14

The instructions that make up a program

Front 15

Coordinate system

Back 15

The graphical coordinate system that allows you to define where on the screen to set a location; uses locations along the x-axis (horizontal) and the y-axis (vertical) to define a specific location on the screen

Front 16

Debug

Back 16

The act of finding and fixing code issues in a program

Front 17

Decimal

Back 17

A date type that holds a floating point or real number with up to 28 digits of decimal significance

Front 18

Delay

Back 18

The system method that causes a program to stop running code execution for a given period of time in milliseconds

Front 19

Function

Back 19

A block of code that returns a value to the instruction that calls it, often used to perform calculations

Front 20

Loop

Back 20

A programming construct that repeats the set of instructions it contains, over and over again, or until an action or a preset condition causes it to end

Front 21

Method

Back 21

A block of code that does something specific, and then returns to the instruction that called it; does not return a value to the calling instruction

Front 22

Parameter

Back 22

A value that is sent "into" a function or method as you call it in your program

Front 23

Pixel

Back 23

A single small dot of color on your screen, which, along with all the other pixels, defines what you see on your screen

Front 24

String

Back 24

A unit of text represented by a sequence of characters surrounded by double quotes; used to manipulate strings of characters

Front 25

Variable

Back 25

Frequently known as objects; stores values that a program needs as it runs; can change over time, as conditions in the program change

Front 26

Digital

Back 26

A type of technology that uses discrete, or discontinuous, values; the discrete values are usually binary numbers (example: computers)

Front 27

Analog

Back 27

A type of technology that uses a continuous range of values (example: VCRs)

Front 28

Integer

Back 28

Any whole number in the range from negative 2,147,483,648 to positive 2,147,483,647

Front 29

For-loop

Back 29

A loop that repeats an action a number of times

Front 30

While-loop

Back 30

A loop that repeats an action until a condition is reached

Front 31

Which of the 3 big ideas in programming use(s) conditions?

Back 31

Iteration and Selection
