Unit 9: Vocabulary

To pass this unit, please study the 20 vocabulary words below.
.NET Framework
a software framework by Microsoft which executes code via a virtual machine
The .NET Framework is Microsoft's premium solution for programming applications, and supports over 20 languages including C#, VB.NET, and IronRuby.
C
a low-level, compiled programming language developed in the early 1970s by Dennis Ritchie for use on the UNIX operating system
C is still a popular programming language 40 years after it was created, mainly due to its minimalism and extreme speed.
C#
Microsoft's premier object-oriented, compiled programming language used with the .NET framework
The .NET programmer used C# as his primary programming language.
C++
an "enhancement" to the C language providing object-oriented programming features
The young programmer decided to learn C++ because he heard it was very popular in game development.
compiler
a program that takes human readable code and turns it into machine readable code for running at a later time
The students liked programming python more than C because they didn't have to use a compiler before execution.
ECMAScript
the official name and standard for the commonly known JavaScript language
The professor told us that officially JavaScript should be called ECMAScript, but that few people do so in practice.
elegant code
concise, clean, and clear code which allows other developers to understand and extend it
The junior programmer wrote elegant code and used variable names with a clear meaning.
interpreter
a program that reads a high-level programming language, converts it into machine code, and then immediately runs that code
Computer languages that require an interpreter often run slower than languages that require a compiler
Java
a high-level, compiled, object-oriented programming language developed by Sun Microsystems.
The computer science professor predicted that as processor speeds increased, Java would eventually replace C++ in application development.
JavaScript
a popular web page scripting language created by Brendan Eich at Netscape to provide client-side interactivity in Web pages.
The web programmer used JavaScript to alert the user about invalid data entered in a required field.
multi-paradigm language
a programming language that supports both procedural and object-oriented programming philosophies
PHP started out as a procedural language, but grew into a multi-paradigm language when it added support for objects in version 4.
object-oriented language
any programming language optimized for modeling real-world objects and concepts
Java is the most popular object-oriented language.
Perl
a high-level, interpreted programming language written by Larry Wall in 1986 and typically used for a wide variety of programming tasks including system administration
Larry Wall is the inventor of Perl, a widely used programming language that has a very devout following.
PHP (PHP Hypertext Preprocessor)
a high-level, interpreted programming language written by Rasmus Lerdorf in 1995 and aimed mainly at web developers creating dynamic applications
The professor said that PHP is the most popular web scripting language in the world and supports many advanced object-oriented programming techniques.
portability
a measure of how easily programs can be moved to a new system without having to make any changes.
Java and ANSI C are two attempts at making software portability a priority.
procedural language
any programming language that is based on a step-by-step approach to solving a problem.
C is the standard example of a procedural language.
Python
a high-level, interpreted programming language developed by Guido van Rossum at CWI in the Netherlands
The motto of Python is "there should be one- and preferably only one- obvious way to do it".
Ruby
an object-oriented, high-level, interpreted programming language developed in the 1990's by ace Japanese programmer Yukihiro Matsumoto.
The creator of Ruby wanted a scripting language that was more elegant than Perl, and more object-oriented than Python.
syntax
rules governing the structure of a programming language
The basic concepts of all programming languages are quite similar, even if the syntax can be quite different.
VB (Visual Basic)
a Windows-only, multi-paradigm programming language developed by Microsoft and intended for beginners or casual use
The high school programming teacher taught his students Visual Basic in his Introduction to Programming class.
