Question 1

Abstraction

Answer 1

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

Question 2

Adaptive technology

Answer 2

In other words, “assistive technology is any object or system that increases or maintains the capabilities of people with disabilities,” while adaptive technology is “any object or system that is specifically designed for the purpose of increasing or maintaining the capabilities of people with disabilities.

Question 3

analog

Answer 3

Analog information has 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

argument

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 that each other is who they say they are

Question 6

Backlog

Answer 6

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

Question 7

Binary

Answer 7

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

Question 8

Boolean expression

Answer 8

A Boolean expression is either True or False. Boolean operators include “and,” “or,” and “not.”

Question 9

Character

Answer 9

Any single typeset unit, including uppercase and lowercase letters, digits, punctuation marks, international characters like letters with accent marks, and special characters like tabs and carriage returns

Question 10

Components

Answer 10

Question 11

Concatenate

Answer 11

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

Question 12

Computational Thinking

Answer 12

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 13

Creative expression

Question 16

Default

Answer 16

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

Question 17

Digital

Answer 17

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 18

Digital Divide

Answer 18

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

Question 19
