Question 3

Lossy compression

Answer 3

A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This process is reversible

Question 4

Lossless compression

Answer 4

A process for reducing the number of bits needed to represent something without losing it any information. This process is reversible

Question 5

Analog data

Answer 5

Data with values that change continuously, or smoothly, over time. Some examples of analog data include music, colors of a painting, or position of a sprinter during a race

Question 6

Digital data

Answer 6

Digital Data - Data that changes discretely through a finite set of possible values Sampling - A process for creating a digital representation of analog data by measuring the analog data at regular intervals

Question 7

Binary

Answer 7

A way of representing info using only two options

Question 8

Bit

Answer 8

• A contraction of “Binary Digit”; the single unit of information in a computer, typically represented as a 0 or 1

Question 9

Byte

Answer 9

8 bits

Question 10

Decimal

Answer 10

A way of representing info using ten options

Question 11

A program

Answer 11

program is a collection of program statements that performs a specific task when run by a computer. A program is often referred to as software.

Question 12

Code segment

Answer 12

Is a collection of program statements that is part of the program

Question 13

Always know

Answer 13

A program needs to work for a variety of inputs and situations

Question 14

The behavior of the program

Answer 14

how a program functions during execution and is often described by how a user interacts with it

Question 15

Computing innovation

Answer 15

innovation includes a program as an integral part of its function
A computing innovation can be physical (e.g., self-driving car), nonphysical computing software (e.g., picture editing software), or a nonphysical computing concept (e.g., e

Question 16

Effective calloboration

Answer 16

produces a computing innovation that reflects the diversity of talents and perspectives of those who designed it.

Question 17

Consultation and communication

Answer 17

with users are important aspects of the development of computing innovations.

Question 18

Program inputs

Answer 18

are data sent to a computer for processing by a program. Input can come in a variety of forms, such as tactile, audio, visual, or text.
Events can be generated when a key is pressed, a mouse is clicked, a program is started, or any other defined action occurs that affects the f low of execution. CRD-2.C.4 Inputs usually affect the output produced by a program

Question 19

Event-driven programming

Answer 19

program statements are executed when triggered rather than through the sequential flow of control.

Question 20

Input

Answer 20

Can come from a user or other programs

Question 21

Program outputs

Answer 21

are any data sent from a program to a device. Program output can come in a variety of forms, such as tactile, audio, visual, or text.

Question 22

Logic error

Answer 22

A logic error is a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.

Question 23

Syntax error

Answer 23

A syntax error is a mistake in the program where the rules of the programming language are not followe

Question 24

Run-time error

Answer 24

I.3 A run-time error is a mistake in the program that occurs during the execution of a program. Programming languages define their own runtime errors.

Question 25

Overflow error

Answer 25

An overflow error is an error that occurs when a computer attempts to handle a number that is outside of the defined range of values.
The following are effective ways to find and correct errors: § test cases § hand tracing § visualizations § debuggers § adding extra output statement(s)

Question 26

Program documentation

Answer 26

is a written description of the function of a code segment, event, procedure, or program and how it was developed. CRD-2.G.2

Question 27

Comments

Answer 27

are a form of program documentation written into the program to be read by people and do not affect how a program runs.

Question 28

Programmers

Answer 28

should document a program throughout its development. Program documentation helps in developing and maintaining correct programs when working individually or in collaborative programming environments. Not all programming environments support comments, so other methods of documentation may be required

Question 29

Cod etiquette

Answer 29

Acknowledge code segments use from the sources

Question 30

Code etiquette

Answer 30

It is important to acknowledge any code segments that were developed collaboratively

Question 31

Acknowledge code segments

Answer 31

segment(s) written by someone else and used in a program can be in the program documentation. The acknowledgement should include the origin or original author’s nam

Question 32

The design

Answer 32

phase of a program may include: §brainstorming §planning and storyboarding §organizing the program into modules and functional components §creation of diagrams that represent the layouts of the user interface §development of a testing strategy for the program

Question 33

Development process

Answer 33

Can be ordered an intentional l, explore nature

Question 34

What are the multiple development processes

Answer 34

The following phases are commonly used when developing a program: § investigating and reflecting § designing § prototyping § testing

Question 35

A development process

Answer 35

development process that is iterative requires refinement and revision based on feedback, testing, or reflection throughout the process. This may require revisiting earlier phases of the process. A development process that is incremental is one that breaks the problem into smaller pieces and makes sure each piece works before adding it to the whole. c

Question 36

A development process

Answer 36

development process that is iterative requires refinement and revision based on feedback, testing, or reflection throughout the process. This may require revisiting earlier phases of the process. A development process that is incremental is one that breaks the problem into smaller pieces and makes sure each piece works before adding it to the whole. c
