Answer: B) Shape is a base class, and circle and square are derived classes of Shape.
Explanation: 
 Shape is a base class because circle and squares are the shapes so these are the derived class of the shape, which is inherited by the shape like circle and square. As, the base class (shape) is the class which are derived from the other classes like circle and square and it facilitates other class which can simplified the code re-usability that is inherited from the base class. Base class is also known as parent class and the super class.  
 
        
             
        
        
        
Answer:
Hardware.
Explanation:
All electronics devices like computer servers, DVDs, smartphones and cell phones, wrist watches etc, comes with two main components, they are hardware and software.
The hardware components are the physical part of the device, while the software component is the written instructions configured to the hardware for executing tasks.

Answer:
2^7= 128
Explanation:
An instruction format characterizes the diverse part of a guidance. The fundamental segments of an instruction are opcode and operands. Here are the various terms identified with guidance design:  Instruction set size tells the absolute number of guidelines characterized in the processor.  Opcode size is the quantity of bits involved by the opcode which is determined by taking log of guidance set size.  Operand size is the quantity of bits involved by the operand.  Guidance size is determined as total of bits involved by opcode and operands.
 
        
             
        
        
        
Answer:
Cloud Landscape
They must evangelize the benefits of cloud computing to company executives in order to assist them in developing and extracting business benefits that will give them a competitive advantage and increase profits
Explanation:
The most successful organisations carefully plan out a multiyear effort to improve their cloud adoption, focusing on multiple streams of work across several stages of maturity.
Cloud computing governance is difficult even when only one cloud provider is involved, and it becomes even more difficult as organisations move toward multi cloud.
Continuous workload placement analysis involves reassessing workloads at a regular cadence, evaluating whether the current execution venue sufficiently meets the organization’s needs and if migrating to an alternative model provides higher value without adding significant risk to the organization’s operations
