$|$Test $1$ Review Questions:

Chapter $1$

$1$: Define and explain algorithm. We begin with a definition as a series of steps for solving a problem or carrying out a

task.

$2$: a set of instructions that performs a specific task when executed by a digital device is referred to as

this as much as possible.

$3$: Why are computer scientists interested in algorithm efficiency, speed and reliability?

$4$: Is algorithm restricted to only one alternative?

$5$: what is a standard algorithm processing?

$6$: What term refers to the process of dividing an extensive app into smaller parts? $($b$)$ Explain this concept. $($c$)$ when do

you use this concept?

$7$: Suppose a programmer is functionally decomposing a two$-$factor authentication process. Which example illustrates a

module that requires further decomposition?

A: Prompt for user ID$.$

C: Generate a one$-$time PIN.

B: Prompt for password.

D: Validate user ID and password match. $(*)$

$8$: How does dependencies and cohesion relate to decomposition?

$9$: Which term refers to the process of finding similarities in procedures and tasks?

a$.$ pattern identification

b$.$ decomposition

c$.$ computational thinking

d$.$ abstraction

Recognizing that each user of a social media site has a login credential set is an example of pattern

identification.

$10$: Define and give examples of a repetitive pattern.

$11$: What is a classification pattern $-$ define and explain.

An example of a classification pattern is vehicles represented as cars

$12$: Which term refers to a technique that hides details, simplifies complexity, and substitutes a generalization for

something specific?

$($note: the black box concept is an implementation of this concept$)$

Chapter $2$:

$13$: Which term refers to code that can be distributed as computer software, desktop applications, web apps, and mobile

apps?

$14$: a: What is the syntax of a programming language?

$b$ : The meaning and validity of a programming language is referred to as

c: Give $2$ examples of what action will cause a syntax error:

d: Give $2$ examples of what action will cause a runtime error $($aka bugs$)$:

$($this error occurs while the program is running after being successfully compiled$)$

e: Give $2$ examples of what action will cause a logic error:

$15$: What is IDE and what are they used for?

$16$: The $3$ essential programming tools are:

$,$ build tools, and

$($note: Build tools provide a programmer with a way to express an algorithm using the vocabulary of a

programming language$)$

$17$: What tool assists a programmer in writing program code

$18$:

tool is a software utility that begins with the first statement in a program, preprocesses it into a binary

instruction, and then executes it$.$ This software utility analyzes each statement one by one in the program.

$19$ tool translates code written in one programming language into another language. Thus software utility

preprocesses and converts all of the statements in a program into a binary file before handing it over for execution.

$20$:

tool is specially designed for entering high$-$level programming code without including extraneous codes

$($code editor$)$
