Scripting and Remote Access Flashcards
Which statement about scripting languages is true?
Scripting languages require a computer
Scripting languages are strongly typed
Scripting languages are interpreted
Scripting languages are interpreted
Scripting languages are interpreted languages that run on top of a runtime environment. Programming languages, not scripting languages, require a compiler. Scripting languages are not strongly typed; programming languages are strongly typed. Scripting languages have bad memory management because of loosely typed variables
What level are scripting languages considered?
High
Mid
Low
High
Scripting languages are considered high-level languages because they do not directly access hardware and use an intermediary called the interpreter. Mid-level languages are Java and C/C++, not scripting languages. There is no such thing as an intermediate-level language. Low-level languages are machine language and assembly language, which are not scripting languages
Which type of variable will allow decimal math?
Integer
Floating point
String

PowerShell
VBScript
Windows batch script
PowerShell
The PowerShell scripting language allows for the use of the .NET Framework and is commonly used with Microsoft Azure and Office 365. The VBScript language allows for the use of the Component Object Model (COM) and is not used for cloud services. Windows batch script uses existing applications and is not used for cloud services. JavaScript is primarily web browser–based, does not allow for the use of external objects, and is not used for cloud services
Which scripting language is used within pages to allow for interactive content?
PowerShell
Bash
JavaScript
JavaScript

Which scripting language has its own preinstalled Integrated Scripting Environment (ISE)?
Bash
Python
PowerShell
PowerShell
PowerShell is the only scripting language that has a preinstalled Integrated Scripting Environment (ISE), called the PowerShell ISE.
