Deck 2: The Javascript Language

Question 1

A register is a short-term memory location in the processor.

Answer 1

True

Question 2

Answer 2

False

Question 3

FORTRAN is considered a first-generation language.

Answer 3

False

Question 4

The Java language was enhanced in the 1980s to incorporate object-oriented programming (OOP).

Question 5

Interpreted programs can be modified and tested immediately.

Question 6

JavaScript is considered an interpreted language because it is interpreted by a Web browser.

Question 7

JavaScript is embedded in an HTML file and interpreted by a Web browser, such as Mozilla Firefox, Internet Explorer, Google Chrome, or Safari.

Question 8

4GLs are associated with visual interfaces and natural languages in some definitions.

Question 9

Machine code is compiled into bytecode by a just-in-time compiler.

Question 10

Fourth-generation languages are "application specific"-that is, they are tied to an application such as a database or a report writer.

Question 11

Mosaic was released in 1995, Netscape Navigator in 2000, and Microsoft Internet Explorer in 2002.

Question 12

JavaScript was first known as Mocha.

Question 13

HTML uses a system of tags to identify sections of a Web page.

Question 14

E-mail and File Transfer Protocol (FTP) are two applications that use the Internet as their principal medium.

Question 15

Credit for the development of JavaScript goes to Bill Gates of Microsoft Corporation.

Question 16

JavaScript programs are compiled and run separately as standalone programs.

Question 17

A principle of XHTML is that it contains the content of data and leaves the formatting specifics to external documents, such as Cascading Style Sheets (CSS).

Question 18

In object-based programming, a statement is often made up of two parts: the name of the object initiating an action (such as document) and the action itself.

Question 19

In pseudocode, the keyword Display is followed by the text expression. In JavaScript, the document.write is followed by the text expression in parentheses, and a semicolon is placed at the end of the statement.

Question 20

JavaScript, like most full programming languages, requires the declaration of a data type.

Question 21

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

Question 22

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

Question 23

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

Question 24

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.

Question 25

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