Some ways investigation can be performed are as follows:

-collecting data through surveys -user testing -interviews -direct observations

Program

A collection of program statements that performs a specific task when run by a computer.

Code segment

a collection of program statements that is part of a program

Comments (#)

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

Types of interpersonal skills

communication. consensus building, conflict resolution, negotiation

A computer innovation includes a ______ as an integral part of its function

program

What is a program referred as ?

software

Design phase includes

-planning and storyboarding -organizing the program into modules and functional components -creation of diagram that represent the layouts of the user interface -development of a testing strategy for for the program

two things about inputs

1. inputs usually affect the output produced by a program 2. input can come from a user or other programs

Logic error

A mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly

Run-time

A mistake in the program that occurs during the execution of a program.

Syntax error

A mistake in the program where the sales of the programming language are not followed

Overflow

An error that occurs when a computer attempts to handle a number that is outside of the defined range of values

What should acknowledgement include

Origin and original author's name

What is important to acknowledge about any code segments

That they were developed collaboratively or by another source

What is the purpose of computing innovations?

To solve problems or pursue interest through creative expression

Program outputs

any data sent from a program to a device.

Event

associated with an action and supplies input data to a program.

Collaboration includes diverse perspectives that helps avoid what in in the development of computing innovations

avoid bias

Development process

can be ordered and intentional, or exploratory in nature.

Consultation and _______________ are important aspects of the development of computing innovaitons

communication with users

a nonphysical computing ______ (e.g. e-commerce)

concept

Program inputs

date sent to a computer for processing by a program

Program speficiation

defines the requirements for the program

Program requirements

describe how a program functions and may include a description of user interactions that a program must provide

Development process steps

investigating and reflecting, designing, protyping, testing

program documentation

is a written description of the function of a code segment, event, procedure, or program and how it was developed. Helps in developing and maintain correct programs when working individually or with others

What happens if the development process is incremental

is one that breaks the problem into smaller pieces and makes sure each piece works before adding it to the whole

Investigation

is useful for understanding and identifying the program constraints as well as the concerns and interests of the people who will use the program

Design phase

outlines how to accomplish a given program specification

An example of common models

pair programming: exist to facilitate collaboration

Effective collaboration produces a computing innovation that reflects the diversity of talents and _________ of those who designed it

perspectives

A computing innovation can be _____ (e.g self-driving car)

physical

Information gathered from _________ can be used to understand the purpose of a program from diverse perspectives and to develop a program that fully incorporates these perspectives

potential users

What happens in event-driven programming

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

What happens if the development process is itertive

requires refinement and revision based on feedback, testing, or reflection throughout the process. this may require revisiting earlier phases of the process

nonphysical computing _______(e.g. picture editing software)

software

Variety forms of an input

tactile, audio, visual, or text

Program output can come in a variety of forms, such as

tactile, audio, visual, or text.

Effective ways to find and correct errors

test cases, hand tracing, visualizations, debuggers, adding extra output statement(s)

Defined inputs

used to test a program should demonstrate the different expected outcomes that are at or just beyond the extremes (minimum and maximum) of input data.

How do online tools support collaboration?

By allowing programmers to share and provide feedback on ideas and documents
