Design Process (Lesson 8)

Question 1

SDLC stands for?

Answer 1

System development life cycle

Question 2

The ___ phase defines a program’s goals.

Answer 2

analysis phase

Question 3

The ___ phase defines specifics of how to build a program.

Answer 3

design phase

Question 4

The ___ phase involves writing the program.

Answer 4

implementation phase

Question 5

The ___ phase checks that the programs correctly meets the goals.

Answer 5

testing phase

Question 6

A programmer is asked to make a finance software for an accounting firm that helps them with calculations. He decides that this finance software will support the five most common statistical calculations used in finance: mean, median, mode, max, and min.

What SDLC phase is this?

Answer 6

analysis; the problem that must be solved is presented and goals are thought of

Question 7

A programmer making a weight loss app for joggers decides it will respond to voice command input; the user speaks a command to invoke each of the algorithms that calculate approximate calories burned, time spent at rest, or distance traveled.

What SDLC phase is this?

Answer 7

design; he has started to define the specifics of how the program will be built

Question 8

A programmer begins writing functions using statements in a spell checking software. These functions compare an input word to common typos he has organized in an array. If there is a match it returns a true statement and outputs “Typo detected”

What SDLC phase is this?

Answer 8

implementation; the writing the program has begun.

Question 9

When working on a project a programmer checked that each function for her software was working properly.

What SDLC phase is this?

Answer 9

testing; they have begun ensuring the program meets the initial goals.

Question 10

A program can be built by carrying out the SDLC phases in a linear sequence, known as the

Answer 10

Waterfall approach

Question 11

A program can be built by doing small amounts of each SDLC phases in sequence, and then repeating is known as the

Answer 11

Agile approach (AKA spiral approach)

Question 12

Which approach is more responsive to user feedback about a program?

Answer 12

Agile

Question 13

In which approach would carrying out one phase, like implementation, likely take longer?

Answer 13

Waterfall

Question 14

A grouping of data, and functions that can be performed on that data, in order to keep them easy to understand

Answer 14

Objects

Question 15

Programs commonly are not viewed as variables and functions/methods, but rather as ___

Answer 15

Objects

Question 16

___ means to have a user interact with an item at a high-level, with lower-level internal details hidden from the user.

Answer 16

Abstraction

Question 17

ADT stands for what?

Answer 17

abstract data type

Question 18

a data type whose creation and update are constrained to specific well-defined operations.

Answer 18

abstract data type (ADT)

Question 19

A code design for creating an object that is composed of data members and functions that operate on those data members.

Answer 19

class

Question 20

Objects strongly support ___, exposing only certain functions to a user.

Answer 20

abstraction

Question 21

A modeling language for software design that uses different types of diagrams to visualize the structure and behavior of programs.

Answer 21

Universal Modeling Language (UML)

Question 22

UML stands for what?

Answer 22

Universal Modeling Language

Question 23

A ___ visualizes static elements of software, such as the types of variables and functions used in the program.

Answer 23

structural diagram

Question 24

A ___ visualizes dynamic behavior of software, such as the flow of an algorithm.

Answer 24

behavioral diagram

Question 25

A ___ is a flowchart used to describe the flow of an activity or set of activities.

Answer 25

activity diagram

Question 26

Should a behavioral diagram or a structural diagram should be used for the following?

A list of components necessary to build an online shopping system.

Answer 26

Structural; A list of components describes the system’s structure, not behavior.

Question 27

Should a behavioral diagram or a structural diagram should be used for the following?

An overview showing how a customer uses a particular software product.

Answer 27

Behavioral; A diagram showing how a customer uses a program would describe the customer’s behavior, so a behavioral diagram is best.

Question 28

Should a behavioral diagram or a structural diagram should be used for the following?

A flowchart illustrating a program’s logic, including operations, branches, and loops, for converting a multiple temperature measurements from C to F.

Answer 28

Behavioral; A flowchart/activity chart, illustrating an algorithm’s operations is a behavioral UML diagram.

Question 29

A behavioral diagram used to visually model how a user interacts with a software program.

Answer 29

use case diagram

Question 30

Actions from users and the accompanying actions in software, as well as connections between different components of the software, are illustrated in a ___. Often used to specify behavioral requirements of programs.

Answer 30

use case diagram

Question 31

A UML ___ is a structural diagram that can be used to visually model the classes of a computer program, including data members and functions.

Answer 31

class diagram

Question 32

A behavioral diagram that shows interaction between software components and indicates the order of events.

Answer 32

sequence diagram

Question 33

The analysis phase of each approach commonly produces a ___, a document describing all requirements for the software product.

Answer 33

software requirements specification (SRS)

Question 34

Programs may be developed in various phases known as the ___

Answer 34

SDLC
