True/False: In many programming languages such as Java and 'C' the evaluation of an expression that employs operators such as greater than, less than, and, or and not (employing the proper syntax) returns a type of boolean.

true

True/False: In object oriented programming languages such as Java, polymorphism refers to the ability of a class to have more than one method of the same name where the appropriate method is invoked based upon the number and type of arguments and/or the return type.

true

True/False: Loop statements are the most difficult statements to program.

true

True/False: Most scripting languages are interpreted.

true

True/False: Python is a programming language that has the diverse characteristics of being interpreted, byte-compiled, interactive, and object-oriented.

true

True/False: The Assembler language was an early step towards abstraction that allowed programmers to use symbols for machine instructions and not binary numbers?

true

True/False: The IBM model of virtualization evolved from mainframe technology and was based upon the mapping of instructions from the virtual machine to physical machine.

true

True/False: The Scope of a variable refers to the domain where a specific binding refers to the same location in memory.

true

True/False: The Unix virtual machine model implements virtualization through the use of process shells.

true

True/False: The basic regular expression is pattern matching?

true

True/False: The following code segment represents a valid declaration of a variable in JavaScript. var KeepVar;

true

True/False: The following expression in Prolog is valid. ?- loves(mary,john) = loves(John,Mary).

true

True/False: The front end of a compiler is language-dependent and the back-end is computer dependent.

true

True/False: The main purpose of an abstract class is to be inherited by other classes.

true

True/False: The object of a derived class can perform all the tasks that an object of base class can perform.

true

True/False: The real disadvantage of call-by-reference is that the mechanism is inherently unsafe.

true

True/False: The scope of a binding is the part of the program (textually) in which the binding is active.

true

True/False: They key limitation of ASCII was that it could only represent 255 characters ?

true

True/False: Type checking will validate, strongly typed programming languages, that the type of an expression is consistent with the type of a target variable.

true

True/False: in Perl, the pragma 'strict' simulates static typing.

true

True/False: in syntactical analysis the top-down approach is referred to LL analysis?

true

True/False: non-imperative languages are referentially transparent which means that a particular state is not required for successful and consistent computation.

true

True/False: the assembler language was an early step towards abstraction that allowed programmers to use symbols for machine instructions and not binary numbers?

true

True/False: the development of the C language is associated with the development of the Unix operating system?
