1.1

Question 1

Abstraction

Answer 1

Procedural abstraction gives a name to a procedure. People can then use the procedure without worrying about the finer grain details.

Question 2

Adaptive Technology

Answer 2

Adaptive technology helps increases or maintains the capabilities of a person with a disability.

Question 3

Analog

Answer 3

Analog information has a continuous values instead of jumping from one value to another value without passing through the values in between. Most physical information such as position, wind speed, light intensity, or sound pressure, is analog.

Question 4

Arguments

Answer 4

The values that a program provides to a function

Question 5

Authentication

Answer 5

When two parties exchange information so that they trust each other is who they say they are

Question 6

Automation

Answer 6

Automation is using an system (often a computer)to do something with less human attention than the task would otherwise require. Examples: automated manufacturing of clothing, security image analysis, or automated vegetable planting.

Question 7

Backlog

Answer 7

A priorities list of features or user stories to add to a program

Question 8

Binary

Answer 8

Binary information is written only using only two values: zero and one. Everything can be a Approximately represented using binary representation.

Question 9

Boonlean expression

Answer 9

A Boolean expression is either true or false. Boolean operators include “and”, “or”, and “not”.

Question 10

Character

Answer 10

Any single typeset unit, including uppercase letter, digits, punctuation marks and special characters like tabs and carriage returns.

Question 11

Collaboration

Answer 11

The action of working with someone to produce or create something.

Question 12

Components

Answer 12

Parts of an interface.

Question 13

Conatenate

Answer 13

To tack together two strings of characters, making one longer string.

Question 14

Computational thinking

Answer 14

Habits that help people solve problems with computers. Computational thinking habits cause a person who is facing a problem to ask how computers could help them be more creative, to communicate, to collaborate, to use data or the Internet, or to use crowdsourcing or simulation, to solve a problem.

Question 15

Creative expression

Answer 15

Computing helps people create sound, movies, 2D media such as screen images or paper art, 3D media including computer-controlled subtractive art (milling) or additive art (3D printing), user interface design, user experience design.

Question 16

Data collection and analysis

Answer 16

Data can be generated by sensors like thermometers, cameras, microphones, and keyboards and collected in storage. Data analysis uses creative ways to see patterns in data and using mathematics to describe those patterns.

Question 17

Decomposition

Answer 17

A problem solving strategy of breaking a problem apart into smaller subproblems.

Question 18

Default

Answer 18

A default value is a value that a variable will have if no action is taken by the user.

Question 19

Digital

Answer 19

Digital information has discrete values with gaps between the values. Digital information can be exactly represented using a binary representation. Digital information can be duplicated exactly, without loss in quality. Digital information can be transmitted error-free.

Question 20

Digital divide

Answer 20

The contrast between two groups’ access to computing resources and the Internet on the basis of race, wealth, or national boundaries.

Question 21

Economic

Answer 21

The contrast between two groups’ access to computing resources and the Internet on the basis of race, wealth, or national boundaries.

Question 22

Economic impact

Answer 22

Economic impacts of computing include changes in the numbers types, and wages of jobs, and changes in the amount, type, and cost of services, goods, and materials produced.

Question 23

Evaluate

Answer 23

To determine the result of an expression.

Question 24

Event

Answer 24

An action that triggers an event handler to be executed, such as user input or a timer’s alarm.

Question 25

Event handler

Answer 25

A part of a program that runs when an event occurs.

Question 26

Global variable

Answer 26

A variable that can be used anywhere in a program, unlike a local variable, which can only be used in one portion of a program. In App Inventor, procedures, event handlers, and for loops can create a local variable that can only be used inside that procedure, event handler, or for loop.
