The
answer is (A): with contextual tabs for major groupings of editing features and
ribbons with specific groupings to organize commands.
Contextual
tab or tabs are hidden menu that appears when objects like images or texts are
selected in programs like MS Word 2013. They typically contain one or more
commands applicable to a selected text or object only. They are there in the

Explanation:
If a program is intended to be able to process large amounts of data, then the ability of the program to process larger data sets is heavily affected by
- execution time
- size of memory the program requires
- storage space the program requires as it runs.
The length of the statements the program contains does not much affect program performance.
Answer:
The key difference between a library and a framework is “Inversion of Control”. When you call a method from a library, you are in control. But with a framework, the control is inverted:the framework calls you
Explanation:
A library performs specific, well-defined operations.
A framework is a skeleton where the application defines the "meat" of the operation by filling out the skeleton. The skeleton still has code to link up the parts but the most important work is done by the application.
Examples of libraries: Network protocols, compression, image manipulation, string utilities, regular expression evaluation, math. Operations are self-contained.
Examples of frameworks: Web application system, Plug-in manager, GUI system. The framework defines the concept but the application defines the fundamental functionality that end-users care about.
