A source A producing fixed-length cells is required to use a Token Bucket Traffic Shaper (TBTS) of bucket capacity b=20 cell tokens and token feed rate r=40 tokens/sec, followed by a FIFO buffer with output read rate (peak rate) limited to q=120 cells/sec. The output is A’s flow into the network. What is the long-term average cell rate for this flow?
Answer:
Please find the detailed answer as follows:
Explanation:
Long-term average cell rate is also called as sustained cell rate(SCR). It can be defined as the maximum average cell rate in a log time period(T).
The relation among the SCR, Average cell rate and Peak cell rate is as follows:
Avg.cell rate ≤ SCR ≤ PCR
If the source producing fixed-length cells at constant rate, then the long-term average cell rate will be same as peak cell rate(PCR).
Trainers at Tom’s Athletic Club are encouraged to enroll new members. Write an application that allows Tom to enter the names of each of his 25 trainers and the number of new members each trainer has enrolled this year. Output is the number of trainers who have enrolled 0 to 5 members, 6 to 12 members, 13 to 20 members, and more than 20 members.
Answer:
The applicatiion and its program output are given below
Explanation:
start
declaration:
int numberOfMember,totalNumber,j=0
string array05[totalNumber],array612[totalNumber],array1320[totalNumber],arrayMore20[totalNumber]
string trainerName;
Loop start:
for i=0-totalNumber
totalNumber=number of trainers
trainerName=name of trainer
numberOfMember=number of memberas added
if numberOfMember=0-5
array05[j]=trainerName;
elseif numberOfMember=6-12
array612[j]=trainerName;
elseif numberOfMember=13-20
array1320[j]=trainerName;
else
arrayMore20[j]=trainerName;
j+=1;
end loop
Output:
for i=0-j
print array05[i] array612[i] array1320[i] arrayMore20[i]
End
The subject at hand revolves around the creation of a computer program for Tom's Athletic Club to register trainers and their new member enrollments. The application would collect trainer names and the count of their respective enrollments, then divide them into categories based on membership numbers. Ultimately, the application would output the number of trainers in every group.
Explanation:The problem describes setting up an application for the needs of a company, specifically Tom's Athletic Club. It implies around a computer program that collects data from user input, in this case, the names of 25 trainers and the number of new members they have enlisted for the year. The output that the application must produce is a segmentation of the number of trainers based upon the class of members they've registered - 0 to 5, 6 to 12, 13 to 20, or more than 20.
In this scenario, we would write the application in a way that captures and calculates this information. For instance, in Python, we would create lists to store the names of trainers and the respective new members. Further on, using conditional statements, we could sort the trainers into the required groups based on the number of new members enrolled. The result would be the quantity of trainers in each category, which could then be displayed as the result.
This problem combines aspects of data collection, data analysis, and program construction, which are integral components of computer programming and software development processes.

Write an application that throws and catches an ArithmeticException when you attempt to take the square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on it. The application either displays the square root or catches the thrown Exception and displays the message Can't take square root of negative number
The code for the program described in question:
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
double number;
double squareRootOfNumber;
String userInput = null;
Scanner scanner = new Scanner(System.in);
System.out.println("Enter the number: ");
userInput = scanner.next();
number = Double.parseDouble(userInput);
squareRootOfNumber = Math.sqrt(number);
if (number < 0) {
throw new ArithmeticException("Can't take square root of negative number");
}
System.out.format("Square root of number entered is %.2f %n", squareRootOfNumber);
}
}
The output of the program will be:
Enter the number:
-90
Exception in thread "main" java.lang.ArithmeticException: Can't take square root of negative number at com.brainly.ans.Test.main(Test.java:18)
Explanation:
Function from standard Java library java.lang.Math.sqrt will not throw an ArithmeticException even its argument is negative so there is no reason to surround your code try/catch block.
Instead, we have thrown ArithmeticException manually by using throw keyword:
throw new ArithmeticException("Can't take square root of negative number");
What is the difference between write back and write through?
A. With write back, main memory is updated immediately, but with write through, the memory is updated only when the block is replaced.
B. With write through, main memory is updated immediately, but with write back, the memory is updated only when the block is replaced.
C. With write through, the block is replaced when it is written, but with write back, it is replaced when it is read.
D. With write through, the block is replaced when it is read, but with write back, it is replaced when it is written.
E. They are two names for the same thing.
The difference between write back and write through is With write through, the block is replaced when it is read, but with write back, it is replaced when it is written.
D. With write through, the block is replaced when it is read, but with write back, it is replaced when it is written.
Explanation:
Write back and write through difference as follows.
Write back update the memory cache at specific intervals times with specific conditions. Memory cache is update on corresponding memory location, which makes faster to desktop or workstation or tablet.
Written through is copied caching techniques data copied to higher level caches. Basically it copy from memory cache only. In write through mode just refresh main memory.
So write back update memory cache on specific intervals whereas write through copy the cache and make memory refresh with fresh updates.
Given an input array of strings (characters) s, pick out the second column of data and convert it into a column vector of data. Missing data will be indicated by the number 9999. If you encounter missing data, you should set it to the average of the immediately neighboring values. (This is a bit simpler than using `interp1`.)
If the input array is s = [ 'A' '0096' ; 'B' '0114' ; 'C' '9999' ; 'D' '0105' ; 'E' '0112' ]; then the output variable `t` is the following column vector. t = [96 114 109.5 105 112]';
Compose a function read_and_interp which accepts an array in the above format and returns the data converted as specified. You may find the conversion function `str2num` to be useful.
(Using MATLAB Syntax only)
Answer:
Consider the following code.
Explanation:
save the following code in read_and_interp.m
function X = read_and_interp(s)
[m, n] = size(s);
X = zeros(m, 1);
for i = 1:m
if(str2num(s(i, 2:5)) == 9999)
% compute value based on previous and next entries in s array
% s(i, 2:5) retrieves columns 2-5 in ith row
X(i,1) = (str2num(s(i-1 ,2:5)) + str2num(s(i+1,2:5)))/2;
else
X(i,1) = str2num(s(i,2:5));
end
end
end

Write a method called digitSum that accepts an integer as a parameter and returns the sum of the digits of that number. For example, the call digitSum(29107) returns 2 9 1 0 7 or 19. For negative numbers, return the same value that would result if the number were positive. For example, digitSum(-456) returns 4 5 6 or 15. The call digitSum(0) returns 0.
Answer:
The cpp program for the scenario is given below.
#include <iostream>
using namespace std;
// method returning sum of all digits in the integer parameter
int digitSum(int n)
{
// variable to hold sum of all digits in the integer parameter
int sum=0;
if(n == 0)
return 0;
else
{
// for negative parameter, consider positive value of the number
if(n<0)
n = abs(n);
// loop to calculate sum till number is greater than 0
do{
sum = sum + (n%10);
n = n/10;
}while(n>0);
}
// sum of all digits in the integer parameter is returned
return sum;
}
int main()
{
// method is called by passing an integer parameter
cout<<"The sum of the digits is "<<digitSum(-14501)<<endl;
return 0;
}
OUTPUT
The sum of the digits is 11
Explanation:
The program works as described below.
1. The method, digitSum(), is defined as having return type as integer and taking input one integer parameter.
int digitSum(int n)
{
}
2. An integer variable, sum, is declared and initialized to 0.
int sum=0;
3. If the input parameter is 0, 0 is returned.
4. If the input parameter is negative, abs() method is used to remove the negative sign.
abs(n);
5. Inside the do-while loop, the sum of all the digits of the input parameter is computed.
do{
sum = sum + (n%10);
n = n/10;
}while(n>0);
6. The digits of the input parameter are obtained by the modulus of n, and added to the variable, sum.
7. Then, n is modified and divided by 10.
8. The digits are obtained using modulus operator on n, and added to the variable, sum till all digits have been added.
9. The loop continues till the value of n is greater than 0.
10. The variable, sum, holding the sum of all digits of the input parameter, n, is returned.
11. The main() method calls the digitSum() method.
12. The program ends with the return statement.
Final answer:
The digitSum method accepts an integer, converts it to a positive if negative, and returns the sum of its digits using a loop to extract and sum each digit.
Explanation:
The digitSum method is designed to accept an integer, treat negative numbers as positive, and then return the sum of its digits. To implement this in a programming language, you can use a loop to iterate through each digit of the number. If the given integer is negative, you can first convert it to a positive by using the absolute value function. After that, repeatedly divide the number by 10 to extract each digit (using modulus operator %), and add it to a sum variable until the number is reduced to 0.
Here's a conceptual implementation:
function digitSum(number) {
let sum = 0;
number = Math.abs(number); // Ensure the number is positive
while (number > 0) {
let digit = number % 10; // Get the last digit
sum += digit; // Add it to the sum
number = Math.floor(number / 10); // Remove the last digit
}
return sum;
}
Note: Math.abs is used to handle negative numbers, and Math.floor is to ensure integer division.
_____________ accepts a table to read data from and optionally a selection predicate to indicate which partitions to scan.
a) HCatOutputFormatb) HCatInputFormatc) OutputFormatd) InputFormat
Answer:
The answer is "Option b"
Explanation:
In the given question the answer is "HCatInputFormat" because it is used to read data from HCatalog controlled table, it also used in MapReduce work and scan the partitions. and other options are incorrect that can be described as follows:
In option a, It is an output format, that is used to show the data, that's why it is not correct.In option c and option, It does not use full name that is HCatalog, that's why it is not correct.Suppose there is a class Roster. Roster has one variable, roster, which is a List of tuples containing the names of students and their number grades--for example, [('Richard', 90), ('Bella', 67), ('Christine', 85), ('Francine', 97)]. Roster has a function findValedictorian that returns the name of the student with the highest grade. Find the valedictorian of the Roster object englishClass and store it in the variable valedictorian.
Answer:
class Roster:
def __init__(self,student):
self.student = student
def findValedictoian(self):
highscore = 0
studentList=[]
bStudent = []
valedictorian =''
for pupil in self.student:
if pupil[1] > highscore:
highscore = pupil[1]
valedictorian = pupil[0]
return valedictorian
student = [('rich', 90), ('Bella', 67),('philip', 56)]
englishClass= Roster(student)
print(englishClass.findValedictoian())
Explanation:
we define the roster class using the class keyword, within the class we have our __init__ constructor and we initialize the variable student.
A class method findValedictoian is defined and it compares the grades of each student and returns the name of the student with the highest grade.
An instance is created for English class and the findValedictorian method is called and the valedictorian is printed to the screen.
UC is importing 1000 records and want to avoid duplicate, how can they do it?
Answer:
By unchecking the 'allow duplicate' box and checking the 'Block duplicate' box in the SalesForce user interface. More also, including a column in the import file that has other record name(SF ID) will ensure no duplicate during import.
Explanation:
importing 1000 records is quiet lengthy and to avoid duplicate it is important to include in the import file that has other record name(SF ID). By including a column that has another file ID every record will be referenced uniquely thereby easily identifying any duplicate.
It is also important to check the ''Block duplicate' box in the salesForce user interface to ensure that records are imported without duplicate.
As the network engineer, you are asks to design an IP subnet plan that calls for 5 subnets, with the largest subnet needing a minimum of 5000 hosts. Management requires that a single mask must be used throughout the Class B network. Which of the following is a public IP network and mask that would meet the requirements?a. 152.77.0.0/21b. 152.77.0.0/17c. 152.77.0.0/18d. 152.77.0.0/19
Answer:
d) 152.77.0.0/19 (255.255.224.0)
Explanation:
If it is required to use a single mask throughout a Class B network, this means that by default, we have 16 bits as network ID, and the remaining 16 bits as host ID.
If we need to set up 5 subnets and we need that the largest subnet can support a minimum of 5000 hosts, we need to divide these 16 bits from the Host ID part, as follows:
Number of hosts = 5000
We need to find the minimum power of 2 that meet this requirement:
2ˣ - 2 = 5,000 ⇒ x = 13
We have left only 3 bits from the original 16, and repeating the process, we find that we need to use the 3 bits in order to accommodate the 5 subnets,
due to with 2 bits we could only support 4.
So, we need that the address mask be, using the CIDR notation, /19, as we need that the first three bits from the third byte to be part of the network ID.
In decimal notation, it would be as follows:
255.255.224.0
The correct IP subnet plan that can support at least 5000 hosts in the largest subnet while using a Class B network and a single mask throughout is 152.77.0.0/19.
Explanation:You are asked to provide an IP subnet plan for a scenario that requires 5 subnets, with the largest subnet supporting at least 5000 hosts, while using a single mask throughout a Class B network. To determine the correct subnet mask, you need to consider the number of hosts required for the largest subnet. Given that each subnet needs to accommodate at least 5000 hosts, the subnet must allow for more than 5000 host addresses. Calculating the number of bits for the host part, 2n - 2 must be greater than 5000 (where n is the number of host bits). This calculation gives us at least 13 bits for the host part (213 - 2 = 8190). Therefore, considering a Class B address starts with 16 network bits, adding 13 bits for the host part totals 29 bits for the network and host. Therefore, the subnet mask should be /19 (32 - 13 = 19) to meet the requirements.
With this in mind, among the given options, 152.77.0.0/19 is the correct network and mask that would meet the requirements as it provides up to 8190 possible host addresses in each subnet, which is more than sufficient for the largest subnet that requires 5000 hosts.
Importance of the need for workstation policies and LAN Domain policies.
Workstation and LAN Domain policies are crucial for defining rules around account security, including password creation, account reactivation, and secure internal communication. These policies protect digital systems from unauthorized access and misuse while preparing the organization for future technological advancements. They create an ethical framework for users to interact with the organization's technological resources.
The importance of having workstation policies and LAN Domain policies lies in maintaining a secure and efficient technological environment within an organization. Account policies can be defined for a domain to enforce rules on user accounts, which include Password Policies, Account lockout policies, and Kerberos Policies. These policies help in regulating access, enhancing security, and setting user expectations through acceptable use policies (AUPs).
For instance, password policies ensure users create strong passwords, which need to be changed after a certain period, increasing the security of organizational systems. Account lockout policies, on the other hand, define the process of regaining access to an account, minimizing the risk of unauthorized access. The Kerberos policy, which is part of a domain's security policy, facilitates secure communication within networks.
Additionally, the use of technology policies needs to accommodate for future innovation and the impact of technology on the workplace and families. Organizations, including school districts, should have clear Technology Use Policies that outline the appropriate use of their systems and the potential consequences of misuse to ensure that all users are aware of the ethical use of computational system.

nt[] num = new int[100];for (int i = 0; i < 50; i++)num[i] = i;num[5] = 10;num[55] = 100;What is the value of num.length in the array above?1. 02. 1003. 994. 101
Answer:
Option 2. 100 is correct.
Explanation:
In the above example, we have assigned the value 100 to the array num[] while creating the object of that array.
In the next line, we are assigning the values to the array num[] through the loop which will be executed till less than 50 values as it will be started from 0 but in the next line from that we are getting the total number of elements of that array which will be 100 because length function is used to get the total number of elements in the array which is already assigned as 100.
To print the last element in the array named ar, you can write :A. System.out.println(ar.length);
B. System.out.println(ar[length]);
C. System.out.println(ar[ar.length]);
D. None of these
Answer:
Option (d) is the correct answer.
Explanation:
An Array is used to store multiple variables in the memory in the continuous memory allocation on which starting index value is starting from 0 and the last index value location is size-1.
In java programming language the array.length is used to tells the size of the array so when the user wants to get the value of the last element, he needs to print the value of (array.length-1) location so the correct statement for the java programming language is to print the last element in the array named ar is--
System.out.println(ar[ar.length-1]);
No option provides the above statement, so option d (None of these) is correct while the reason behind the other option is not correct is as follows--
Option a will prints the size of the array.Option b also gives the error because length is an undeclared variable. Option c will give the error of array bound of an exception because it begs the value of the size+1 element of the array.Describe how your leadership and service has made a positive difference in your school, inyour community, in your family and/or on the job, and how it will continue to make adifference in college and beyond.
I could describe my leadership and service as being motivational and more a credit-giver.
I do not own the credit for every successful task that my team has accomplished. In fact, I am giving them all the recognitions they deserved. In times of struggling and great pressure, I would motivate them. Most of their complaints about my leadership method is I do not give importance to time. I normally tend to finish everything before deadlines. With these attitudes, my family learn to adapt to this behavior. They value ideas and teamworks in their respective workplace and like me, they would also hate to submit their works late. They would sometimes get positive feedback from clients for finishing their assigned tasks on time.
File Letter Counter
Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file. Use Notepad or another text editor to create a sample file that can be used to test the program.
The C++ program prompts the user for a file name and a character, counts the occurrences of the character in the file, and displays the result. Error handling is included.
Below is a simple C++ program that accomplishes the task described:
```cpp
#include <iostream>
#include <fstream>
using namespace std;
int main() {
string fileName;
char targetChar;
cout << "Enter the name of the file: ";
cin >> fileName;
cout << "Enter the character to count: ";
cin >> targetChar;
ifstream inputFile(fileName);
if (!inputFile) {
cerr << "Error opening file. Make sure the file exists." << endl;
return 1;
}
int charCount = 0;
char currentChar;
while (inputFile.get(currentChar)) {
if (currentChar == targetChar) {
charCount++;
}
}
cout << "The character '" << targetChar << "' appears in the file " << charCount << " times." << endl;
inputFile.close();
return 0;
}
```
This program prompts the user to enter a file name and a character. It then opens the specified file, counts the occurrences of the specified character, and displays the result. If the file is not found, it provides an error message.

Define a function below called nested_list_string. The function should take a single argument, a list of lists of numbers. Complete the function so that it returns a string representation of the 2D grid of numbers. The representation should put each nested list on its own row. For example, given the input [[1,2,3], [4,5,6]] your function should produce the following string: "1 2 3 \n4 5 6 \n" Hint: You will likely need two for loops.
Answer:
The solution code is written in Python:
def nested_list_string(list2D): output = "" for i in range(0, len(list2D)): for j in range(0, len(list2D[i])): output += str(list2D[i][j]) + " " return outputExplanation:
Let's create a function and name it as nested_list_string() with one input parameter, list2D (Line 1).
Since our expected final output is a string of number and therefore we define a variable, output, to hold the string (Line 2).
Next use two for loops to traverse every number in the list and convert each of the number to string using str() method. Join each of individual string number to the output (Line 3-5).
At the end, we return the output (Line 7)
The 'nested_list_string' function converts a list of lists of numbers into a string that visually represents a 2D grid, with each sublist converted to a row of numbers separated by spaces, and rows separated by newlines.
The function called nested_list_string should be defined to take a list of lists of numbers as its argument and return a string representation of the 2D grid. To achieve this, you will need to use a nested for loop. The outer loop will iterate over each sublist (which represents a row of the grid), and the inner loop will iterate over each number in the sublist, converting it to a string and appending it to a string variable along with spaces. The \n character is used to move to the next line after each sublist is processed, thus simulating rows.
Here's an example code:
def nested_list_string(list_of_lists):Given an input like [[1,2,3], [4,5,6]], the nested_list_string function would return '1 2 3 \n4 5 6 \n'.

John is runnig his Database application on a single server with 24 Gigabytes of memory and 4 processors. The system is running slow during peak hours and the diagnostic logs indicated that the system is running low on memory. John requested for additional memory of 8 Gigabytes to be added to the server to address the problem. What is the resultant type of scaling that John is expecting?
Answer:
Vertical Scaling
Explanation:
Vertical scaling means the ability to increase the capacity of existing hardware or software by adding resources. In this case, more GB is added (8GB) to the server to address the problem. So vertical scaling is the resultant type john is expecting.
Suppose you have the following declaration.int[] beta = new int[50];Which of the following is a valid element of beta.(i) beta[0]
(ii) beta[50]
Answer:
The answer is "Option (i)".
Explanation:
In the given question, an array is defined. It is a collection of the same type of data element, which means, array stores either a numeric value or string value at a time. An array beta is defined, which contains 50 elements. The array elements indexing always starts with 0 which means, the first element of the array will be stored in an index value that is 0. That's why option (i) is correct.int[] num = new int[100];for (int i = 0; i < 50; i++)num[i] = i;num[5] = 10;num[55] = 100;What is the index number of the last component in the array above?1. 992. 1003. 04. 101

Explanation:
As the array is declared with space of 100 integers, 100 integers' space will be allocated to variable num. Moreover, Index number of last component is always the length - 1 because array's index start with 0 and ends till length-1. As array will initialize all the remaining spaces with garbage value so they will be displayed if accessed through num[index] where index s the index number to be displayed.
As size of array is 100. So, 99 will be the index of the last component of the array.
Suppose that sales is a two-dimensional array of 10 rows and 7 columns wherein each component is of the type int , and sum and j are int variables.
Which of the following correctly finds the sum of the elements of the fifth row of sales?1.sum = 0;for(j = 0; j < 10; j++)sum = sum + sales[5][j];
2.sum = 0;for(j = 0; j < 7; j++)sum = sum + sales[4][j];
3.sum = 0;for(j = 0; j < 10; j++)sum = sum + sales[4][j];
4. sum = 0;for(j = 0; j < 7; j++)sum = sum + sales[5][j];
Answer:
sum = 0;for(j = 0; j < 7; j++)sum = sum + sales[5][j];
Explanation:
here we evaluate condition in parenthesis
sum = 0 here variable sum is initialised with 0 value
now for loop executes the condition in parenthesis which is (j = 0; j < 7; j++)
j =0 is 1st condition which will be executed one time , so j = 0 means index value for loop started is with 0 as you know arrays have indexj<7 2nd condition for executing the code block which defines loop will go on till the value of j is less than 7 ,as we know the columns in question is 7(this condition must be true)j++ 3rd condition means after each iteration value of j will increase +1here this condition is true (j = 0; j < 7; j++) till 7th column sum = sum + sales[5][j] (sales [row][column] it indicates every 5th row element of each column)Final answer:
The correct code to find the sum of the elements of the fifth row of the 'sales' array is 'sum = 0; for(j = 0; j < 7; j++) sum = sum + sales[4][j];'.
Explanation:
To find the sum of the elements of the fifth row of the two-dimensional array sales, which has 10 rows and 7 columns, the correct option is to set sum to 0 and then use a loop to iterate over the elements of the fifth row (index 4, since array indexes start at 0) and accumulate their values into sum. The loop should iterate over the number of columns, which is 7.
Therefore, the correct code to achieve this is:
sum = 0;
for(j = 0; j < 7; j++)
sum = sum + sales[4][j];
Notice that we use sales[4][j] because array indexing starts at 0, so the fifth row is at index 4. Also, we iterate up to 7 (the number of columns) rather than 10 (the number of rows).

In a class, why do you include the function that overloads the stream insertion operator, <<, as a friend function? (5, 6)
Answer:
To provide << operator access to non-public members of the class.
Explanation:
Whenever we overload << operator, an object to ostream class has to be passed as this is the class which has properties which allows printing of output to console. Moreover, this operator is used outside class all the time so if not made a global member it will produce conflicts so thats why it has to be made a friend function to allow efficient access to private members of the class. Its declaration inside class is as follows :
friend ostream& operator<<(std::ostream& os, const T& obj) ;
