Answer:

The answer is "option a".

Explanation:

To resolve the automatic reboot problem we must change the CPU cooling fan because if we don't change a computer fan so, it will be heated and damage other components. This cooling fan used inside the CPU. It expels warm air from inside and moves air across the particular component. and other options are not correct that can be described as:

  • In option b, power supply is used to turn on the computer. It is not used to solve the reboot problem.
  • In option c,  Motherboard is to serve as the base upon which a computer's components are built.  
  • In option d, It is primarily used to store the data.

svetlana [45]

Answer:

1. multiplying two numbers when you meant to add them - Logical Error

2. dividing by zero - Compile time error

3. semi colon at the end of a programming statement - Logical error

4. wrong in output - Run time error

5. when you should have typed a - Compile time error

6. producing inaccurate results - Logical error or Run time error

Explanation:

Compile time error is a lack in computer programming which causes to violate the rules which are defined by user in the program.

Run time error produces wrong outputs. It causes lags in the softwares which makes the output inefficient. It even causes programs crash when the output is just seconds away.

Logical error is the situation where programs completes the task assigned but with the wrong syntax. The output is produced with some abnormality.

Write a C++ program to count even and odd numbers in array. The array size is 50. The array elements will be entered by the user
vlabodo [156]

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

int main(){

   int numbers[50];

   int evekount = 0, odkount = 0;

   for(int i = 0; i<50;i++){

       cin>>numbers[i];

       if(numbers[i]%2==0){            evekount++;        }

       else{            odkount++;        }

   }

   cout<<"Even Count: "<<evekount<<endl;

   cout<<"Odd Count: "<<odkount<<endl;

   return 0;

}

Explanation:

This declares the integer array of number

   int numbers[50];

This initializes the even count and odd count to 0

   int evekount = 0, odkount = 0;

This iterates from 1 to 50

   for(int i = 0; i<50;i++){

This gets input for the array

       cin>>numbers[i];

This checks for even

<em>        if(numbers[i]%2==0){            evekount++;        }</em>

This checks for odd

<em>        else{            odkount++;        }</em>

   }

This prints the even count

   cout<<"Even Count: "<<evekount<<endl;

This prints the odd count

   cout<<"Odd Count: "<<odkount<<endl;

Karolina [17]

Answer:

The correct answer to the following question will be "Metadata".

Metadata is "information providing information on other data" This is "data about data", in other words.

There are many subareas of metadata, including:

  • Structural metadata
  • Iscriptive metadata
  • Statistical metadata
  • Reference metadata
  • Administrative metadata

Metadata gives a summary of the features of the data and the collection of relationships that connect the data found in the database.

It defines other details, is a prefix in most uses of computing means "an underlying meaning or description. Very simple document metadata are, for example, creator, date generated and date changed and file size.

Therefore, Metadata is the right answer.

A hub transmits all incoming messages to all of its ports except the port where the messages came in. A switch usually sends mes
leonid [27]

Answer:

MAC Addresses (Destination and Source MAC address)

Explanation:

A switch has 3 primary functions:

  • Forward frames
  • Learn addresses
  • Avoid loops

An Ethernet frame has the header, data and trailer and there are two specific fields in the header that helps the switch to know where to send data in future transmissions.

  • destination MAC address
  • source MAC address

every Ethernet frame has this and when the frame hits a switch or any device, any device can look at it ( an Ethernet frame ) and know where it is suppose to go and where it came from.

Every switch has a MAC address table where it stores MAC addresses of different computers on the network.

Example:

When a PC1 sends a frame to PC2 through a switch, the switch looks at the header of the Ethernet frame for the source mac address and adds the source MAC address to its MAC address table and also the port that it came through.

simply put:

A switch looks at the source MAC address to see if it knows it already, if it does. Great! no need to add it again to it's address table.

If it doesn't, it adds it's source address and the port that the frame came from.

This basically how the switch populates its MAC address table.

andre [41]

Answer:

Explanation:

The following code is written in Java. It creates the loop as requested and validates the information provided before continuing, if the information is invalid it prints "Invalid Information to the screen" and asks the user to enter the information again. Finally, outputing all the requested information at the end of the program. The code has been tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int totalValues = 0;

       int totalTaxes = 0;

       int count = 0;

       while(true) {

           int lotNumber, value;

           double tax;

           System.out.println("Would you like to add an Entry: 1=Yes 0=No");

           int answer = in.nextInt();

           if (answer == 1) {

               System.out.println("Please enter lot number: ");

               lotNumber = in.nextInt();

               if ((lotNumber >= 0) && (lotNumber <= 999999)) {

                   System.out.println("Please enter assessed value: ");

                   value = in.nextInt();

                   tax = value * 0.05;

                   System.out.println("Lot Number: " + lotNumber);

                   System.out.println("Property Value: " + value);

                   System.out.println("Property Tax: " + tax);

                   totalTaxes += tax;

                   totalValues += value;

                   count += 1;

               } else {

                   System.out.println("Invalid Lot Number");

               }

           } else {

               break;

           }

       }

       int average = totalTaxes / count;

       System.out.println("Total Property Values: " + totalValues);

       System.out.println("Total Property Taxes: " + totalTaxes);

       System.out.println("Average Property Tax" + average);

   }

}
