Answer:
1.
Role of communication layer:
-it has the responsibility of transferring information among network controlled devices.
-it provides up to date view of the state of the network to SDN controller which shows that a new device has being added to the network as well as the link that was attached being non-existent.
2.
Role of network wide state management layer:
-it is responsible for the controller having the network's state information
-it also helps in the making of ultimate control decisions.
c
role of network control application layer:
- It is responsible for the reading and also the writing of the state of the network as well as flow tables which are in the layer of state management.
- It also notifies of changes such as state-event change. this helps to take actions with regards to the event notification.
Prove the following using the specified technique:A) Letxandybe two real numbers such thatx yis rational. Prove by contrapositive that ifxis irrational, thenx−yis irrational.B) Prove by contradiction that for any positive two real numbers,xandy, ifx·y≤50, theneitherx <8 ory <8.
Answer:
Following are the solution to this question:
Explanation:
In point A:
The predicate of the whole argument is if x+y is rational and x-y is reasonable, then x is reasonable as well" To see the sum of the two logical estimates is often sound. Let us be two real [tex]\frac{p}{9}[/tex] .rs amount then seeing how.
[tex]\frac{p}{q}+\frac{r}{s} = \frac{(ps+rq)}{qs}[/tex] is logical, too. x Thus if[tex]x + y[/tex] is logical and [tex]x- y[/tex] is true, then [tex]x + y +x- y = 2x[/tex] should be sound.
Let's assume [tex]2x=\frac{p}{q}.[/tex] Therefore the rational [tex]x=\frac{p}{2q}[/tex]proves the necessary statement in the query.
In point A:
Let [tex]x \cdot y \leq 50 \ and \ x \geq 8, \ but \ \geq 8 \\\\[/tex], both to demonstrate it through contradiction. So,[tex]x \cdot y \geq 8\cdot 8 = 64[/tex]. This implies that both [tex]x \cdot y \ and \ \leq 50 \ and x \cdot y \ and \geq 64[/tex] are valid in the very same period. The argument is valid.

I am writing a Python code to ask a user to enter students' information including name,
last name and student ID number. The program should continue prompting the
user to enter information until the user enters zero. Then the program enters
search mode. In this mode, the user can enter a student ID number to retrieve
the corresponding student's information. If the user enters zero, the program
stops. Please help!
Answer:
student_file = {}
endf_input = '1'
for x in iter(list, 1):
name = input("Enter a student name: ")
st_id = int(input("Enter a student id number: "))
student_file[name] = st_id
endf_input = input("Add more student to file (type 1 for yes and 0 to end): ")
if endf_input == '0':
break
print("Search for Student")
search = int(input("Enter student id: "))
if search == 0:
print("Sorry, no student with id of zero.")
quit()
for key, value in student_file.items():
if value == search:
print(f"Student name: {key}")
Explanation:
The program source code uses a for loop to continuously add data to the student file dictionary structure but breaks from the loop when a zero is received as input. The program enters search mode and returns the name of the student with the searched id number.

12.12 LAB: Swapping variables
Write a program whose input is two integers and whose output is the two integers swapped.
Ex: If the input is:
3 8
then the output is:
8 3
Your program must define and call a function. SwapValues returns the two values in swapped order.
void SwapValues(int* userVal1, int* userVal2)
Answer:
#include <stdio.h>
void SwapValues(int* userVal1, int* userVal2)
{
int temp = *userVal1;
*userVal1 = *userVal2;
*userVal2 = temp;
}
int main(void)
{
int a = 3;
int b = 8;
printf("Before swap: a=%d, b=%d\n", a, b);
SwapValues(&a, &b);
printf("After swap: a=%d, b=%d\n", a, b);
return 0;
}
Explanation:
For swapping variables efficiently, you need a helper variable in C or C++.
In an executing process, the program counter points __________.
Answer:
To the next instruction to be executed and is incremented after each instruction has been executed.
Explanation:
Given that Program counter is a form of record or directory in a computer processor that has the location of the instruction that is currently being executed.
This it does in such a way that, following the execution of each instruction, the program counter increases the number of instructions it stored and immediately points to the subsequent instruction that follows.
Hence, in an executing process, the program counterpoints "To the next instruction to be executed and is incremented after each instruction has been executed."

On a client/server network, which computer initiates the process of assigning an IP address through DHCP?
Answer:
The client
Explanation:
On a client/server network, THE CLIENT computer initiates the process of assigning an IP address through DHCP. This is because "The Client" computer will serve as the Domain controller in which other computers of the network can find. Hence, The Client computer initiates the process of assigning IP addresses through DHCP to achieve this.
Though, in some case. A user can manually assign the IP address to computer if it is not through DHCP

How do you see the recent IT evolution (e.g. platforms, big data, Internet of Things, etc.) affect Internet security and privacy of internet users
Answer:
Answered below
Explanation:
With the evolution and growth of technology, and as we are increasingly having our everyday lives dependent on technology, there arise problems that shouldn't be ignored.

Answer:The process of sketching in engineering might resemble a loop because of the design process.
Explanation: The design process is a loop or cycle to improve a design. So, sketches will be shown to other engineers and they will improve on the design until it is effective and efficient.
Answer:
The correct answer includes that the idea is created in the engineer’s imagination and that he or she must sketch the image on a piece of paper in an attempt to capture the essence of the idea. Once the engineer or team sees the sketch, they may want to modify or change the design. Changes will require other sketches and further brainstorming. The cycle will continue until the engineer achieves the best possible design.
