PLTW Computer Science Essentials Unit 2 detailed questions and
answers
IDE
- correct answer Integrated Development Environment (IDE) is a software application that brings
together the tools necessary to write, test, and debug computer programs while they are developed.
Parameter
- correct answer A special kind of variable defined in a function to receive specific information.
"Parameter" and "argument" are often used interchangeably. In this course, we will use the term
"argument".
Variable
- correct answer The smallest unit of data storage that a program can use. A variable contains known or
unknown information referred to as a "value". Two types of variables are global and local.
Decremented
- correct answer Reduced in number by one
Argument
- correct answer The values that a program provides to a function or subroutine. Sometimes coding
professionals use the terms "argument" and "parameter" interchangeably. In this course, argument is a
better choice because Python does not use the term parameter.
Conditional Statement
- correct answer A programming statement that evaluates a true/false Boolean expression to determine
the next steps in a program. Conditional statements are often written as 'if-then' or 'if-then-else'
statements.
Python
- correct answer A text-based language designed to emphasize code readability with a syntax that
allows programmers to express concepts in fewer lines of code than possible in languages such as C++ or
Java. (Python is a registered trademark of the Python Software Foundation.)
