The OSI model is a useful tool in troubleshooting a network because it enables you to isolate a problem to a particular software

lutik1710 [3]

Answer:

1) Layer 4, transport

2) Layer 2, datalink

3) Layer 5, session

4) Layer 7, application

Description of Problems are as below:

1) One of your servers has been exhibiting sluggish network performance. you use a network-monitoring program to try to evaluate the problem. You find considerable TCP retries occurring because the server is being overwhelmed by data, and packets are being discarded.

2) You check some statistics generated by a network-monitoring program and discovers that an abnormally high number of CRC errors were detected. (Hint think of the cause of CRC errors).

3) A user is trying to connect to another computer, but the logon attempt is continually rejected.

4) You try to access a Linux server to share files by using NFS. You can communicate with the server, but the shared files don't appear to be available.

Explanation:

OSI Model is a reference model to determine how applications communicate over a network. OSI consists of seven layers, and each layer performs a particular network function. The seven layers are:

Layer 7 - Application.

Layer 6 - Presentation.

Layer 5 - Session.

Layer 4 - Transport.

Layer 3 - Network.

Layer 2 - Data Link.

Layer 1 - Physical.

Layer 4, transport

The Speed of Sound (Java Project. Please make it easy to understand. I'm a beginner at this. I believe we are supposed to use a

Ilya [14]

Answer:

The program of this question can be given as:

Program:

//import pacakge for user input.

import java.util.Scanner;

//define class

public class SpeedofSound

{

public static void main(String a[]) //define main function

{

//define variable.

String medium;

double distance,time=0;

//creating Scanner class object for input from user.

Scanner s=new Scanner(System.in);

//print message.

System.out.printf("Enter medium(air,water or steel) : ");

medium=s.nextLine(); //taking input.

//print message.

System.out.printf("Enter the distance that the sound will travel : ");

distance=s.nextDouble(); //taking input.

switch(medium) //checking condtion between range.

{

case "air":

time=distance/1100; //apply formula

break;

case "water":

time=distance/4900; //apply formula

break;

case "steel":

time=distance/16400; //apply formula

break;

default:

System.out.printf("Sorry, you must enter air,water or steel"); //error for invalid input of medium

System.exit(0);

}

System.out.printf("It take "+time+" seconds"); //print final answer.

}

Output:

Enter medium(air,water or steel) : air

Enter the distance that the sound will travel : 200

It take 0.18181818181818182 seconds

Explanation:

In this program first, we import packages for user input. Then we declare the class in the class we declare all the variables and then we create the scanner class object. It is used for taking input from the user. Then we use the switch statement It is used for condition. It works between the ranges. In the switch statement, we apply all the formula that is given in the question. and at the last, we print the output using printf function in java.

2.Consider the following algorithm and A is a 2-D array of size ???? × ????: int any_equal(int n, int A[][]) { int i, j, k, m; f

Elis [28]

Answer:

(a) What is the best case time complexity of the algorithm (assuming n > 1)?

Answer: O(1)

(b) What is the worst case time complexity of the algorithm?

Answer: O(n^4)

Explanation:

(a) In the best case, the if condition will be true, the program will only run once and return so complexity of the algorithm is O(1) .

(b) In the worst case, the program will run n^4 times so complexity of the algorithm is O(n^4).

Write a program that asks the user how many numbers will be entered and then has the user enter those numbers. When this is done

KATRIN_1 [288]

Answer:

The program written in Python 3 is as follows;

The program does not make use of comments; however, see explanation section for detailed line by line explanation of the program

num = int(input("Number of Inputs: "))

mylist = []

userinput = int(input("Enter a digit: "))

i = 1

while i < num:

mylist.append(userinput)

userinput = int(input("Enter a digit: "))

i += 1

try:

first7 = mylist.index(7)+1

print('The first position of 7 is ',first7)

last7 = num - 1 - mylist[::-1].index(7)

print('The last position of 7 is ',last7)

except:

print('7 is not on the list')

Explanation:

This line prompts user for the number of inputs

num = int(input("Number of Inputs: "))

This line declares an empty list

mylist = []

This line inputs the first number into the empty list

userinput = int(input("Enter a digit: "))

The italicized lines represent an iteration that allows user to input the numbers into the empty list.

i = 1

while i < num:

mylist.append(userinput)

userinput = int(input("Enter a digit: "))

i += 1

The try-except is used to check the presence of 7 in the list

try:

This checks the first occurrence of 7

first7 = mylist.index(7)+1

This prints the first occurrence of 7

print('The first position of 7 is ',first7)

This checks the last occurrence of 7

last7 = num - 1 - mylist[::-1].index(7)

This prints the last occurrence of 7

print('The last position of 7 is ',last7)

The following is executed if there's no occurrence of 7

except:

print('7 is not on the list')
