Explanation:
question a) answer:
At the moment when it sends the package, then it has a waiting time for the acknowledgement from the receiver, however, the time will be split in two when the frameset size becomes two, meaning that two packages have been sent together, causing the receiver to acknowledge only one package.
question b) answer:
The timeout is equal to two times.
In cases when the frame size is 3, the frame will be lost since the timeout turns to be 2 times. Because the sender has to wait for the acknowledgement, therefore it will send other of the parcels.

If the propagation delay through a full-adder (FA) is 150 nsec, what is the total propagation delay in nsec of an 8-bit ripple-carry adder
Answer:
270 nsec
Explanation:
Ripple-carry adder is a combination of multiple full-adders. It is relatively slow as each full-adder waits for the output of a previous full-adder for its input.
Formula to calculate the delay of a ripple-carry adder is;
= 2( n + 1 ) x D
delay in a full-adder = 150 nsec.
number of full-adders = number of ripple-carry bits = 8
= 2 ( 8 + 1 ) x 150
= 18 x 150
= 270 nsec
How has the rise of mobile development and devices impacted the IT industry, IT professionals, and software development
Answer:
Throughout the interpretation section elsewhere here, the explanation of the problem is summarized.
Explanation:
The growth of smartphone production and smartphone apps and services, as well as the production of smartphones, has had a positive influence on the IT industry, IT practitioners, as well as the development of the technology. As normal, the primary focus is on smartphone apps instead of just desktop software. As we recognize, with innovative features, phone applications, and smartphones are all made, built, modernized every day, and always incorporated with either the latest technology.This has now resulted in far more jobs and employment for the IT sector, and therefore new clients for service-based businesses. It provided various-skilling the application production industry for IT experts including learning how to work on emerging technology. The demand for software production and software growth is evolving at a greater speed than it's ever been, so the increase of smartphone production and smartphones has had a very beneficial effect on perhaps the IT sector, IT practitioners, and business development.Write a program whose inputs are three integers, and whose output is the smallest of the three values. Use else-if selection and comparative operators such as '<=' or '>=' to evaluate the number that is the smallest value. If one or more values are the same and the lowest value your program should be able to report the lowest value correctly. Don't forget to first scanf in the users input.
Ex: If the input is: 7 15 3
the output is: 3
You should sketch out a simple flowchart to help you understand the conditions and the evaluations needed to determine what number is the correct answer. This type of tool can help determine flaws in a logical design.
Answer:
The Program written in C is as follows:
#include <stdio.h>
int main() {
int num1, num2, num3, smallest;
printf("Enter any three numbers: ");
scanf("%d", &num1); scanf("%d", &num2); scanf("%d", &num3);
if(num1 <= num2 && num1 <= num3) {
smallest = num1;
}
else if(num2 <= num1 && num2 <= num3) {
smallest = num2;
}
else {
smallest = num3;
}
printf("Smallest: ");
printf("%d", num3);
return 0;
}
Explanation:
This line declares necessary variables
int num1, num2, num3, smallest;
This line prompts user for input of three numbers
printf("Enter any three numbers: ");
This lines get input for the three numbers
scanf("%d", &num1); scanf("%d", &num2); scanf("%d", &num3);
The following if/else statements determine the smallest of num1, num2 and num3 and assigns to variable smallest, afterwards
if(num1 <= num2 && num1 <= num3) {
smallest = num1;
}
else if(num2 <= num1 && num2 <= num3) {
smallest = num2;
}
else {
smallest = num3;
}
The next two lines print the smallest value
printf("Smallest: ");
printf("%d", num3);

Who is a software engineer
Kara's teacher asked her to create a chart with horizontal bars. Which chart or graph should she use?
Bar graph
Column chart
Line graph
Pie chart
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is the Bar graph.
Because we use this chart type to visually compare values across a few categories when the charts show duration or when the category text is long.
However, we can present information similarly in the bar graph and in column charts, but if you want to create a chart with the horizontal bar then you must use the Bar graph. In an Excel sheet, you can easily draw a bar graph and can format the bar graph into a 2-d bar and 3-d bar chart.
A column chart is used to compare values across a few categories. You can present values in columns and into vertical bars.
A line graph chart is used to show trends over months, years, and decades, etc.
Pie Chart is used to show a proportion of a whole. You can use the Pie chart when the total of your numbers is 100%.

Data Structure in C++
Using namespace std;
In this assignment you will implement a variation of Mergesort known as a bitonic mergesort, recursively.
In a normal mergesort, the input to the merge step is a single array, which is divided into two sections, both sorted ascending. We assume that the first half (0 up to but not including size/2) is the first section and the second half (size/2 up to but not including size) is the second section.
In a bitonic mergesort, we use the same arrangement, except that the second sequence is sorted in descending order: the first half goes up, and then the second half goes down. This means that when we are doing a merge, sometimes we want to merge the results into ascending order, while other times we want to merge into descending order (depending on which "half" of the final array the result will end up in). So we add another parameter, to describe the direction the output should be sorted into:
void merge(int* input, int size, int* output, bool output_asc);
If output_asc == true then after the merge output should contain size elements, sorted in ascending order. If output_asc == false, output should contain the elements sorted in descending order.
The other thing we glossed over in class was the allocation of the temporary space needed by the algorithm. It’s quite wasteful to allocate it in each recursive call: it would be better to allocate all the necessary space up front, and then just pass a pointer to it. In order to do this, we’ll write the recursive mergesort function in a helper function which will preallocate the space needed for the results:
int* mergesort(int* input, int size) {
int* output = new int[size];
mergesort(input, size, output, true);
return output;
}
void mergesort(int *input, int size, int* output, bool output_asc) {
// Your implementation here
}
The parameter output_asc serves the same purpose here as for merge: it tells the function that we want the output to be sorted ascending.
Interface
You must implement the functions
void merge(int* input, int size, int* output, bool output_asc);
int* mergesort(int* input, int size);
void mergesort(int *input, int size, int* output, bool output_asc);
Download a template .cpp file containing these definitions. This file is also available on the server in /usr/local/class/src.
merge must run in O(n) time with n= size. mergesort (both versions) must run in O(nlogn) time, and must use O(n) space. If you allocate any space other than the output array, you should free it before your function returns.
The test runner will test each function separately, and then in combination. It checks the result of sorting to make sure that it’s actually sorted, and then nothing is missing or added from the original (unsorted) sequence.
The code .cpp is available bellow
#include<iostream>
using namespace std;

According to Darwin’s theory of evolution, differences between species may be a result of which of the following?
a) The disuse of body structures
b) The transmission of acquired characteristics
c) Natural selection
d) Mutagenic agents
Answer:
The answer is C Natural selection
Explanation:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations
According to Darwin’s theory of evolution, differences between species may be a result of Natural selection. Thus the correct option is C.
What is Darwin’s theory of evolution?According to Darwin, all species descended from a single ancestor, species can change through time, and new species can arise from existing ones which makes them interconnected with common traits.
Natural selection of traits in a species that would help the species in its survival is the process that drives diversification, the evolutionary process through which new biological species form.
Natural selection is the evolutionary mechanism stating that with many resources available in nature, creatures with genetically inherited features that promote survival and reproduction will typically produce more offspring than their conspecific competitors.
Therefore, option C is appropriate.

Given the dictionary, d, find the largest key in the dictionary and associate the corresponding value with the variable val_of_max. For example, given the dictionary {5:3, 4:1, 12:2}, 2 would be associated with val_of_max. Assume d is not empty.
Answer:
Here is the Python program:
d = {5:3, 4:1, 12:2}
val_of_max = d[max(d.keys())]
print(val_of_max)
Explanation:
The program works as follows:
So we have a dictionary named d which is not empty and has the following key-value pairs:
5:3
4:1
12:2
where 5 , 4 and 12 are the keys and 3, 1 and 2 are the values
As we can see that the largest key is 12. So in order to find the largest key we use max() method which returns the largest key in the dictionary and we also use keys() which returns a view object i.e. the key of dictionary. So
max(d.keys()) as a whole gives 12
Next d[max(d.keys())] returns the corresponding value of this largest key. The corresponding value is 2 so this entire statement gives 2.
val_of_max = d[max(d.keys())] Thus this complete statement gives 2 and assigns to the val_of_max variable.
Next print(val_of_max) displays 2 on the output screen.
The screenshot of program along with its output is attached.
