Question 1

JavaScript has no separate declaration for constants, so constants are declared as variables.

Accepted Answer

JavaScript does not have a separate keyword for declaring constants, so constants are declared as variables using the `const` keyword.

Question 2

Named constants should be used when they serve to improve readability and understanding.

Accepted Answer

Named constants replace specific values with a name that describes what the value represents, making the code easier to read and understand.

Question 3

A number entered in a text box is stored as a numeric variable.

Accepted Answer

A number entered in a text box is typically stored as a string variable and may need to be explicitly converted to a numeric variable for numerical operations.

Question 4

An expression using the + operator between two variables assigned with the prompt() statement concatenates the variables as strings instead of performing arithmetic addition on them.

Accepted Answer

The prompt() function returns a string, so using the + operator between two variables assigned with prompt() will concatenate them as strings, not add them as numbers.

Question 5

In JavaScript, variables are declared with var and the data type must be specified.

Accepted Answer

In JavaScript, variables are declared using var, let, or const, but the data type does not need to be specified as JavaScript is a dynamically typed language.

Question 6

____ consisted of machine languages, written in binary code and executed by the computer's processor.
A) First-generation languages
B) Second-generation languages
C) Third-generation languages
D) Fourth-generation languages

Accepted Answer

First-generation languages are the earliest computer programming languages that were written in binary code, which is directly executed by the computer's processor.

Question 7

With a(n) ____ the editor, compiler, and executer are combined in the same application.
A) graphical browser
B) second-generation language
C) integrated development environment
D) first-generation language

Accepted Answer

An Integrated Development Environment (IDE) combines the editor, compiler, and executer into a single application, streamlining the development process.

Question 8

Complete programs that are translated into complete machine-executable programs are said to be ____.
A) interpreted
B) compiled
C) instantiated
D) validated

Accepted Answer

Compiled programs are translated into machine-executable code, making them ready for execution by the computer's hardware.

Question 9

____ was one of the first languages to have an integrated development environment (IDE).
A) Visual Basic
B) FORTRAN
C) LISP
D) COBOL

Accepted Answer

Visual Basic was one of the first programming languages to provide an integrated development environment (IDE), which significantly simplified the development process by integrating all the tools developers need into a single interface.

Question 10

Which of the following is considered a second generation language?
A) FORTRAN
B) LISP
C) C
D) Assembly language

Accepted Answer

Second generation languages are assembly languages. These are a step above the first generation of programming languages, which were machine languages. Assembly language allows for more readable code, using mnemonic codes and labels instead of binary.

Question 11

Programs translated and executed line by line from the source code are said to be ____.
A) compiled
B) validated
C) interpreted
D) instantiated

Accepted Answer

Interpreted programs are executed line by line from the source code by an interpreter, unlike compiled programs which are translated into machine code before execution.

Question 12

____ programs are free of syntax errors and they run faster than interpreted programs (because they are already in machine executable form).
A) Validated
B) Compiled
C) Assembled
D) Instantiated

Accepted Answer

Compiled programs are translated from high-level programming language to machine language, making them free of syntax errors (as these would prevent compilation) and allowing them to run faster since they are already in an executable form that the computer's CPU can directly execute.

Question 13

____ focus less on a program's procedures and more on the objects (or things) on which these procedures operate.
A) Validated
B) Compiled
C) Assembled
D) Object oriented

Accepted Answer

Object-oriented programming (OOP) focuses on using objects and classes to organize and structure software programs. This approach emphasizes the objects themselves rather than the specific steps involved in manipulating those objects.

Question 14

If a(n) ____ program contains a syntax error it usually just halts or crashes.
A) validated
B) compiled
C) interpreted
D) object oriented

Accepted Answer

Interpreted programs, unlike compiled ones, are executed line by line. If there's a syntax error, the program halts or crashes when it encounters the error during execution. Compiled programs, in contrast, would not compile successfully if there's a syntax error, preventing execution from starting. Validation and object orientation are not directly related to how syntax errors affect program execution.

Question 15

A(n) ____ is one that does not run as a separate (stand-alone) program.
A) second-generation language
B) scripting language
C) first-generation language
D) interpreted language

Accepted Answer

A scripting language is typically embedded within another program and does not run as a stand-alone program.

Question 16

____ are segments of program code that another program runs.
A) Scripts
B) Tags
C) Hyperlinks
D) Methods

Accepted Answer

Scripts are segments of program code executed by another program or interpreter, often used for automating tasks or adding functionality to websites and applications.

Question 17

In the early 1990s, search tools with the names Archie, Gopher, Veronica, and Jughead established the use of ____, which made it possible to click a text link and retrieve a document from another location in the vast Internet resources known as "cyberspace."
A) hyperlinks
B) tags
C) functions
D) objects

Accepted Answer

Hyperlinks are the technology that allows users to click on a text link and access a document from another location on the Internet, which was a fundamental feature of early search tools like Archie, Gopher, Veronica, and Jughead.

Question 18

In 1989, ____ developed Hypertext Markup Language (HTML), which became the language of the modern Internet, and Hypertext Transfer Protocol (HTTP), which specified how communication should take place.
A) Bill Gates
B) Tim Berners-Lee
C) IBM
D) Larry Page

Accepted Answer

Tim Berners-Lee is credited with developing HTML (Hypertext Markup Language) and HTTP (Hypertext Transfer Protocol) in 1989, foundational technologies for the World Wide Web.

Question 19

____ is a markup language, meaning it describes the layout of a Web page onscreen.
A) Java
B) HTML
C) C++
D) Visual Basic

Accepted Answer

HTML stands for HyperText Markup Language, which is specifically designed to describe the structure and layout of web pages by using a variety of tags and attributes.

Question 20

The collection of HTML pages stored, transmitted, and displayed on the Internet is known as the ____.
A) URL
B) graphical browser
C) World Wide Web
D) Hypertext Transfer Protocol

Accepted Answer

The World Wide Web (WWW) is the collection of HTML pages that are accessed via the Internet. It is a system of interlinked hypertext documents that are accessed through the Internet.
