File transfer, remote login, and video on demand need connection-oriented service.

Explanation:

I HOPE THIS HELPS

A connection-oriented service is a data transfer mechanism used at the session layer. Connectionless service is an in-data communication that is used to convey data at the OSI model's transport layer.

A connection-oriented service is a data transfer mechanism used at the session layer. Unlike its opposite, connectionless service, connection-oriented service necessitates the establishment of a session connection between the sender and recipient, similar to a phone conversation. Although not all connection-oriented protocols are considered reliable, this method is generally thought to be more reliable than a connectionless service.

Connectionless service is a notion in data communications that is used to convey data at the OSI model's transport layer (layer 4). It refers to data transmission between two nodes or terminals in which data is transferred from one node to the other without first confirming that the destination is accessible and ready to accept the data. There is no need for a session connection between the sender and the receiver; the sender just begins delivering data.

Telnet, rlogin, and FTP are examples of services that leverage connection-oriented transport services. And Connectionless services include User Datagram Protocol (UDP), Internet Protocol (IP), and Internet Control Message Protocol (ICMP).

Complete Question:

Write a method getIntVal that will get the correct value input as integer numbers from the user. The input will be validated based on the first two numbers received as parameters.

In other words, your program will keep asking for a new number until the number that the user inputs is within the range of the <firstParameter> and <secondParameter>.

The method should present a message asking for the value within the range as:

Please enter a number within the range of (<firstParameter> and <secondParameter>):

Note that <firstParameter> should be changed by the value received as that parameter and <secondParameter> as well.

If the user inputs a value that it is lower than the first value, the program will show the message:

The input number is lower than <firstParameter>

Note that <firstParameter> should be changed by the value received as that parameter

If the user inputs a value that it is greater than the first value, the program will show the message:

The input number is greater than <secondParameter>

Note that <secondParameter> should be changed by the value received as that parameter.

You do not need to modify anything in the main method, you just need to write the missing parts of your new getIntVal method.

Answer:

#include<iostream>

using namespace std;

void getIntVal(int num1, int num2) {

int num;

cout<<"Please enter a number within the range of "<<num1<<" and "<<num2<<": ";

cin>>num;

while(num<num1 || num>num2) {

if(num<num1) {

cout<<"The input number is lower than "<<num1<<endl;

}

if(num>num2) {

cout<<"The input number is greater than "<<num2<<endl;

}

cout<<"Please enter a number within the range of "<<num1<<" and "<<num2<<": ";

cin>>num;

}

cout<<"Output: "<<num;

}

int main() {

int num1,num2;

cout<<"Enter lower bound: ";

cin>>num1;

cout<<"Enter upper bound: ";

Nested lists __________ is a tool for building a new list from another list by applying an expression to each item in a sequence.

Explanation:

The nested list can contain any sort object, even another list (sublist), which in turn can contain sublists themselves, and so on.  Nested lists can be used to arrange data in hierarchical structures.  Some nested lists are unordered lists, some are ordered lists, and others are description lists.  The most important observation of a nested list is that it usually appears as an element on another list.

Answer:

1.111 second

Explanation:

We know propagation speed =  [tex]$2 \times 10^8$[/tex] m/s

                                                 =  [tex]$2 \times 10^5$[/tex] km/s

One packet size = 1000 bit

Distance between sender and the receiver = 1000 m = 1 km

The channel data rate = 1 Mbps =   [tex]$1 \times 10^6$[/tex] bits per sec

There is no transmission delays of ACKs,

The time to transmit one data packet  = [tex]$T_{trans}+2T_{prop}$[/tex]

Here, time to transmit frame = [tex]$T_{trans}$[/tex]

          propagation time = [tex]$T_{prop}$[/tex]

Therefore, [tex]$T_{trans}$[/tex] = [tex]$\frac{bits\ per\ frame}{transmission \ speed}$[/tex]

                            = [tex]$\frac{1000}{1 \times 10^6}$[/tex]      = 0.001 seconds

[tex]$T_{prop}=\frac{distance\ between\ sender\ and\ receiver}{propagation \ speed}$[/tex]

         = [tex]$\frac{1}{2 \times 10^5}$[/tex]            

         = 0.000005 seconds

Therefore, T = 0.001 +2(0.000005)

                     = 0.00101 seconds

We known, 1.1 million bits= 1100 packets

Therefore to transmit 1 million bits = 1100 x 0.00101

                                                         =  1.111 second

Answer:

1. import java.util.*;

2. public class SmallestInArrayExample1{

3. public static int getSmallest(int[] a, int total){

4. Arrays.sort(a);

5. return a[0];

6. }

7. public static void main(String args[]){

8. int a[]={1,2,5,6,3,2};

Explanation:

Here is some coding information.

import java.util.Arrays;

public class SmallestIntArray{

   public static int getSmallest(int[] a){

       Arrays.sort(a);

       return a[0];

   }

   public static void main(String []args){

       int a[] = {1,2,3,4,5,0,1};

       System.out.println(getSmallest(a));

   }

}

The method getSmallest takes one arguement, an array of integers. The integers are then sorted in ascending order (smallest number first) then we return the first integer in the array.

import java.util.Arrays;

public class SmallestIntArray{

   public static int getSmallest(int a, int b, int c, int d, int e, int f){

       int ar[] = {a, b, c, d, e, f};

       Arrays.sort(ar);

       return ar[0];

   }

   public static void main(String []args){

       System.out.println(getSmallest(1,2,3,4,5,0));

   }

}

The method getSmallest takes 6 integers as arguements and then puts them into an array. We then sort that array in ascending order and we get the smallest number by returning the first integer in the array.

Answer:

Four (4) IP fragments will be created by the router to forward this packet.

Explanation:

Datagram = 2700 bytes

IP Header = 20 bytes

Maximum Transmission Unit = 900 bytes

Original datagram is stamped with an identification number of 15

Required number of fragments = [tex]\frac{Datagram - IP header}{MTU - IP header}[/tex]

⇒  [tex]\frac{2700 - 20}{900 - 20}[/tex]

⇒  2680 / 880 = 3.045

ceiling(3.045) = 4

Answer:

True.

Explanation:

In object-oriented programming language, a process known as encapsulation is used for the restrictions of the internal data of a software program from the outside code, therefore preventing an unauthorized direct access to the codes. This is achieved through the use of classes.

When an object's internal data is hidden from outside code and access to the data is restricted to the object's methods, the data is protected from accidental corruption.

Answer:

Follows are the code to this question:

class Animal //defining a class Animal

{

static int count = 0;//defining static integer variable count

int myCount;//defining integer variable myCount

Animal() //defining default constructor Animal

{

myCount = ++count;//use myCount to hold incrementing value of count

}

public static int getCount()//defining a static method getCount

{

return count;//return count value

}

public static void setCount(int count)//defining a static method setCount that accept a parameter

{

Animal.count = count;//use class to hold value in count variable  

}

public int getMyCount() //defining a method getMyCount

{

return myCount;//return myCount value

}

}

public class Main//defining a class Main

{

public static void main(String[] ax)//defining main method  

{

Animal a1 = new Animal();//creating animal class object

Animal a2 = new Animal();//creating animal class object

Animal a3 = new Animal();//creating animal class object

System.out.println("Number of created animals: " + Animal.getCount());//calling static method

System.out.println("Number of created animals: " + Animal.getCount());//calling static method

System.out.println("Number of created animals: " + Animal.getCount());//calling static method

System.out.println("first animal count: " + a1.getMyCount());//calling getMyCount method

System.out.println("second animal count: " + a2.getMyCount());//calling getMyCount method

System.out.println("third animal count: " + a3.getMyCount());//calling getMyCount method

}

}

Output:

please find the attached file.

Explanation:

please find the complete question in the attached file.

In the above-given code, a class "Animal" is defined, inside the class two integer variable "count and myCount" is defined, in which "count" is the static variable.

In the next step, the class constructor is defined that holds the incrementing value of count in the myCount variable, and use the get and set method to hold the value, in which set is static type.

In the main class, the "Animal" class object is created, which calls the getMyCount method to print its value and use the class name to call the set method.
