____ increase network performance by reducing the number of frames transmitted to the rest of the network

1 answer:

6 0

Switches increase network performance by reducing the number of frames transmitted to the rest of the network.

Switches are an integral part of networks assigned the role to serve as the means to share information among different devices.

Switches perform their function by supervising and controlling the flow of data to the intended devices thus preventing the undesired flow of data to all the devices in a network which improves the performance of the network. Switches can also play a role to prevent errors as it checks the data prior to transmitting the data forward.

Switches determine the devices to which the data packets are to be sent by using their media access control (MAC) address. All hardware units connected to a system have their unique MAC address. Switches identify the MAC address of the device that sends the frames and then interpret the MAC address of the target device thus preventing the frames to pass towards the rest of the network.

Travel agents are market intermediaries who make their living by gathering, organizing, and dispensing information about travel-

Oliga [24]

Answer:

A. Travel agents routinely use the internet and other new information technologies as sources for the information they obtain for their customers

Explanation:

These travel agents also have access to this information on the Internet and because of it, they know the prices these airlines and hotels put up on their website and regulate their own prices, making it cheaper, so as to remain in business.

The travel agents can also gather, organise and dispense travel related information at a more affordable rate. These travel agents will access the travel and booking information from the airlines, hotels, etc and go ahead to make logistics that will make the journey easier, cheaper and more enjoyable to their customers.

The advent of travel information on the internet that is also accessed by the travel agents will not necessarily reduce the importance of the travel agents, it will merely make them offer better services because they now have a serious competitor which is ease of information on the internet.

Write a program that takes a point (x,y) from theuser and find where does the point lies. The pointcan

agasfer [191]

Answer:

C++ Program .

#include<bits/stdc++.h>

using namespace std;

int main()

{

int x,y;//declaring two variables x and y.

string s;//declaring string s..

cout<<"enter x and y"<<endl;

cin>>x>>y;//taking input of x and y..

if(x>=0 &&y>=0) //condition for 1st quadrant..

cout<<"the point lies in 1st Quadrant"<<endl;

else if(x<=0 &&y>=0)//condition for 2nd quadrant..

cout<<"the point lies in 2nd Quadrant"<<endl;

else if(x>=0 &&y<=0)//condition for 3rd quadrant..

cout<<"the point lies in 3rd Quadrant"<<endl;

else //else it is in 4th quadrant..

cout<<"the point lies in 4th Quadrant"<<endl;

cout<<"enter n to terminate the program"<<endl;

while(cin>>s)//if the user has not entered n the program will not terminate..

{

if(s=="n")

{

cout<<"the program is terminated"<<endl;

exit(0);

}

cout<<"you have not entered n please enter n to terminate the program<<endl;

}

Explanation:

The above written program is for telling the point lies in which quadrant.I am first declaring two variables x and y.Then after that taking input of x and y after that checking in which quadrant the point lies.

Taking input of the string s declared earlier for program termination the program will keep running until the user enters n.

Which of the following commands would instruct OSPF to advertise ONLY the 192.168.10.0/24 network in Area 0?

xz_007 [3.2K]

Answer:

First, you need to start the OSPF process by executing the command:

Router (config)# router ospf {process-ID#}

Then, you have to instruct the router to advertise the networks that are directly linked to it by entering this network command with the area ID number for that network:

Router (config-router)# network {192.168.10.0} {255.255.255.0} area {0}

Write a recursive method to return the number of uppercase letters in a String. You need to define the following two methods. Th

satela [25.4K]

Answer:

Recursive function with two parameters that return the number of uppercase letters in a String

public static int count(String str,int h)//Defining function

{

if(str.charAt(0)>='A' && str.charAt(0)<='Z')//Checking the characters from A to Z

{

h++; //incrementing the counter

if(str.length()>=2){

return count(str.substring(1),h);//recalling function

}

if(str.length()>=2){

return count(str.substring(1),h); //recalling function

}

return h;

}

This is the recursive function with the name count of return type integer,having parameters str of string type and h of integer type.In this we are checking the characters at a particular position from A to Z.

Recursive function with one parameter that return the number of uppercase letters in a String

public static int count(String str)//Defining function

{

if(str.charAt(0)>='A' && str.charAt(0)<='Z')//Checking the characters from A to Z

{

count++; //incrementing the counter

if(str.length()>=2){

return count(str.substring(1));//recalling function

}

if(str.length()>=2){

return count(str.substring(1)); //recalling function

}

return count;

}

This is the recursive function with the name count of return type integer,having parameters str of string type .In this we are checking the characters at a particular position from A to Z.

Java program that return the number of uppercase letters in a String

import java.util.*;

public class Myjava{

static int count =0;//Defining globally

public static int count(String str,int h)//Defining function

{

if(str.charAt(0)>='A' && str.charAt(0)<='Z')//Checking the characters from A to Z

{

h++;

//incrementing the counter

if(str.length()>=2){

return count(str.substring(1),h);//recalling function

}

if(str.length()>=2){

return count(str.substring(1),h);

//recalling function

}

return h;

}

public static void main(String[] args)//driver function

{

System.out.println("Enter a string");//taking input

Scanner scan = new Scanner(System.in);

String s = scan.nextLine();

int h =0;

System.out.println("Counting the Uppercase letters: "+count(s,h));

}

Output

Enter a string WolFIE

Counting the Uppercase letters: 4
