Answer and Explanation:
Messages flow across an SDN controller's:
Northbound APIs:
• Messages which help in read/write state of the network and developing flow tables within the
state management layer.
• Notifications for the state-change events.
• The interaction between the controller and network control applications is done through the
northbound interface.
• Network control applications send messages to the controller.
Southbound APIs:
• Messages which help for the up-to-date view of the network's state like message for the
attached link has gone up or down, new devices are joined the network, or indications of the
device is up or down.
• Controller's southbound interface is the communication among the controller and the controlled
devices. Controlled devices are the recipients of the messages sent form the controller.
Answer:
C. Binary can be used to represent more complex, higher level abstractions, including but not limited to numbers, characters, and colors. D. When data is large enough computers switch to using decimal representation instead of binary, because you can represent larger numbers with fewer digits
Explanation:
Answer:
continual user involvement gives the flexibility to analyze the requirements in right direction. because there is continuous meetings with the end user and he can provide right direction or avoids wrong interpretation of the requirement
Explanation:
continual user involvement is useful when we are following agile methodology where we are building complex systems. it is not useful for simple sytems and following waterfall methodology
Answer:
c. classification
Explanation:
In the given situation, since you want to know what attributes shared among the most loyal customers for this you want to use the data mining software that refers to convert the raw data into the useful information so that it could become meaningful for the organization
In order to know about the characteristics we have to use the classification so that we get to know the characteristics i.e shared among the trusted customers
In Python, tuples are indeed a data structure that also stores an ordered sequence of unchanging values, and following are the Python program to the given question:
Program Explanation:
- Defining a method "add_tuples" that takes three variables "firstTuple, secondTuple, thirdTuple" into the parameter.
- After accepting the parameter value a return keyword is used that adds a <em><u>single tuple with two values</u></em> and returns its value into the form of (x,y).
- Outside the method, two print method is declared that calls the above method by passing value into its parameters.
Program:
def add_tuples(firstTuple, secondTuple, thirdTuple):#defining a method add_tuples that takes three variable in parameters
return firstTuple[0]+secondTuple[0]+thirdTuple[0],firstTuple[1]+secondTuple[1]+thirdTuple[1] #using return keyword to add value
print(add_tuples((1,4), (8,3), (14,0)))#defining print method that calls add_tuples method takes value in parameters
print(add_tuples((3,2), (11,1), (-2,6)))#defining print method that calls add_tuples method takes value in parameters
Output:
