The fraction 460/7 is closest to which of the following whole numbers?
Consider a Stop-and-Wait protocol. Assume constant delays for all transmissions and the same delay for packets sent and ACKs sent. Assume no errors occur during transmission.
(a) Suppose that the timeout value is set to 1/2 of what is required to receive an acknowledgement, from the time a packet is sent. Give the complete sequence of frame exchanges when the sender has 3 frames to send to the receiver.
(b) Suppose that the timeout value is sent to 2 times the round trip time. Give the sequence of frame exchanges when 3 frames are sent but the first frame is lost.
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.

Explanation:
Your program is correct and doesn't need an attachment.
However, there's a mismatch in placement of curly braces in your program
{
}
I've made corrections to that and I've added the corrected program as an attachment.
Aside that, there's no other thing to be corrected in your program.
Use another compiler to compile your program is you are not getting the required output.
Read the following code:
x = 1
while(x < 26)
print(x)
x = x + 1
There is an error in the while loop. What should be fixed?
1. Add a colon to the end of the statement
2. Begin the statement with the keyword count
3. Change the parentheses around the test condition to quotation marks
4. Use quotation marks around the relational operator
This is python code.
In python, you are supposed to put a colon at the end of while loops. This code does not have a colon after the while loop, therefore, you need to add a colon to the end of the statement.
The error to be fixed in the while loop is to add a colon at the end of the while statements.
x = 1
while (x<26)
print(x)
x = x + 1
This is the right code;
x = 1
while(x < 26):
print(x)
x = x + 1
The actual code , the while statement is missing a colon at the end of it.
The code is written in python. In python while or for loops statements always ends with a colon.
In the error code, there was no colon at the end of the while loop.
The right codes which I have written will print the value 1 to 25.

What is the maximum number of VLANs that can be configured on a switch supporting the 802.1Q protocol? Why?
Answer:
4096 VLANs
Explanation:
A VLAN (virtual LAN) is a group of devices on one or more LAN connected to each other without physical connections. VLANs help reduce collisions.
An 802.1Q Ethernet frame header has VLAN ID of 12 bit VLAN field. Hence the maximum number of possible VLAN ID is 4096 (2¹²). This means that a switch supporting the 802.1Q protocol can have a maximum of 4096 VLANs
A lot of VLANs ID are supported by a switch. The maximum number of VLANs that can be configured on a switch supporting the 802.1Q protocol is 4,094 VLANS.
All the VLAN needs an ID that is given by the VID field as stated in the IEEE 802.1Q specification. The VID field is known to be of 12 bits giving a total of 4,096 combinations.But that of 0x000 and 0xFFF are set apart. This therefore makes or leaves it as 4,094 possible VLANS limits. Under IEEE 802.1Q, the maximum number of VLANs that is found on an Ethernet network is 4,094.

What is python?A high-level, all-purpose programming language is Python. Code readability is prioritized in its design philosophy, which makes heavy use of indentation. Python uses garbage collection and has dynamic typing. It supports a variety of paradigms for programming, including functional, object-oriented, and structured programming.
Python is a popular computer programming language used to create software and websites, automate processes, and analyze data. Python is a general-purpose language, which means it may be used to make many various types of applications and isn't tailored for any particular issues.
Sorting in Python simply means putting the data in a specific format or order. The order of the data pieces can be sorted either ascendingly or descendingly. Python programming contains certain built-in functions that allow you to sort the list's elements, just like C++ and Java.
Therefore, Thus option (C) is correct.

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);

The government of a country wants to know how much inbound tourism (number of tourists visiting from other countries) is contributing to the country’s economic prosperity. The research firm hired to conduct this study surveys 10,000 residents on their favorite spots to visit in the country and how much money they spend on leisurely activities
a. How could the use of a sample like this threaten the value of the study’s outcomes?
b. How might the flawed sample affect the usefulness of the results?
Answer and Explanation:
A. The study by the research team may not reflect the purpose of the research which is to know how much inbound tourism is contributing to the economy. They are sampling the population on their favorite spots to visit( which may be too narrow here) and what their leisure activities are (which are not the only things tourists spend on). Also 10000 residents may be too small as a sample to reflect more accurate study outcome representative of the population.
2. A flawed sample which is a sampling error would not represent the population as the results from sample would contradict population results

sum_even Write a program that reads an integer 0 < n < 2^32, returns the sum of all digits in n that are divisible by 2. For example, if n = 341238 the output would be 14, because it is the sum of 4 + 2 + 8. Hint: a signed int may not be enough.
Answer:
Written in Python
n = int(input("Num: "))
sum_even = 0
if n > 0 and n < 2**32:
strn = str(n)
for i in range(0,len(strn)):
if int(strn[i])%2 == 0:

Explanation:
This line prompt user for input
n = int(input("Num: "))
This line initializes sum_even to 0
sum_even = 0
This line checks for valid input
if n > 0 and n < 2**32:
This line converts input to string
strn = str(n)
This line iterates through each digit of the input

This if condition checks for even number
if int(strn[i])%2 == 0:
This adds the even numbers
sum_even = sum_even+ int(strn[i])
This prints the sum of all even number in the user input
