15

Development Environment -DefinitionFrom:

http://searchsoftwarequality.techtarget.com/definition/development-environment

An Integrated Development Environment (IDE) is one in which the processes and tools are coordinated to provide developers an orderly interface to and convenient view of the development process or at least the processes of

Writing code, Testing code, and Packaging code for use.

16

Development Environment - Definition

From: http://searchsoftwarequality.techtarget.com/definition/integrated-development-environment

IDE is a programming environment that has been packaged as an application program, typically consisting of

a code editor, a compiler, a debugger, and a graphical user interface (GUI) builder.

The IDE may be a standalone application or may be included as part of one or more existing and compatible applications. The BASIC programming language, for example, can be used within Microsoft Office applications, which makes it possible to write a WordBasic program within the Microsoft Word application.

Cloud computing - refers to the use of resources and

applications hosted remotely on the Internet.

The term comes from the image of a cloud to represent the Internet or some large networked environment.
