The process by which one object can acquire the properties of another object?

• Encapsulation
• Inheritance
• Polymorphisim
• Abstraction

An object that has more than one form is referred to as...

• Inheritance
• Interface
• Abstract
• Polymorphism

These controls the behavior of a program.

• class
• object
• method
• void

An object is an instance of a:

• parameter
• method
• class
• application

As a blueprint is a design for a house, a class is a design for a(n):

• object
• variable
• constant
• statement

Information hiding can also be terms as...?

• Polymorphisim
• Inheritance
• Encapsulation
• Data Hiding

Von Neumann advantage...

• Only one data bus so less complex for the control unit to manage
• The separation of data and instructions and two buses means that processes can be carried out in parallel.

Harvard disadvantage..

• This architecture can only process one instruction / item of data at a time.
• More complex architecture and so is more expensive and takes longer to manufacture

This type of instruction set will have a large amount of known instructions (for example 80-100) and these will be complex in nature (i.e. each instruction may represent several steps)

• CISC
• RISC

RISC Processors This type of instruction set has a much smaller amount of known instructions (for example 30-40).

• As a result, in RISC, more instructions are required to perform a task.
• As a result, in RISC, less instructions are required to perform a task.
