4) a) List two hardware devices that are associated with the Data Link layer. b) Which is the most commonly used in modern Ethernet networks

Answer:

4

Explanation:

Given

The attached code segment

Required

The output

The first and second lines initialize num2 to 32 and num1 to 12, respectively.

Next, the remainder is calculated on line 3

[tex]rem = 32\%12[/tex]

[tex]rem = 8[/tex]

Then the while loop is repeated as long as rem > 0.

At first, we have:

[tex]num2 = 32[/tex]

[tex]num1 = 12[/tex]

[tex]rem = 8[/tex]

The first iteration gives:

[tex]num2 = 12[/tex]

[tex]num1 = 8[/tex]

[tex]rem = 12\%8 = 4[/tex]

Is 4 > 0? Yes; The loop is executed again.

This gives:

[tex]num2 = 8[/tex]

[tex]num1 = 4[/tex]

[tex]rem = 8\%4=0[/tex]

Is 0 > 0? No; The loop is executed

The last statement prints the last value of num1;

In the last loop, we have:

[tex]num1 = 4[/tex]

Hence, the output is 4

Answer:

Following are the solution to the given question:

import java.util.Scanner;//import package

public class AscendingAndDescending//defining a class AscendingAndDescending  

{

   public static void main(String[] args) //main method

   {

       int n1,n2,n3,min,max,m;

       Scanner in = new Scanner(System.in);//creating Scanner class object

       System.out.print("Enter an integer: ");//print message

       n1 = in.nextInt();//input value

       System.out.print("And another: ");//print message

       n2 = in.nextInt();//input value

       System.out.print("And just one more: ");//print message

       n3 = in.nextInt();//input value

       min = n1; //use min variable that holds value

       max = n1; //use mix variable that holds value

       if (n2 > max) max = n2;//use if to compare value and hols value in max variable

       if (n3 > max) max = n3;//use if to compare value and hols value in max variable

       if (n2 < min) min = n2;//use if to compare value and hols value in min variable

       if (n3 < min) min = n3;//use if to compare value and hols value in min variable

       m = (n1 + n2 + n3) - (min + max);//defining m variable that arrange value

       System.out.println("Ascending: " + min + " " + m + " " + max);//print Ascending order value

       System.out.println("Descending: " + max + " " + m + " " + min);//print Descending order value

   }

}

Output:

Enter an integer: 8

And another: 9

And just one more: 7

Ascending: 7 8 9

Descending: 9 8 7

Explanation:

In this program inside the main method three integer variable "n1,n2, and n3" is declared that inputs value from the user end and also defines three variable "min, max, and m" that uses the conditional statement that checks inputs value and assigns value according to the ascending and descending order and prints its values.

a. A workstation with a 3.9 GHz quad-core processor, 16 gigabytes of RAM, and a 24" monitor.

Explanation:

From the description, Jane needs to be able to multitask and run various programs at the same time in order to be efficient. Also since she wants to play the latest video games she will need high end hardware. Therefore, from the available options the best one would be a workstation with a 3.9 GHz quad-core processor, 16 gigabytes of RAM, and a 24" monitor. This has a very fast cpu with 4 cores to process various threads at the same time. It also has 16GB of memory to be able to multitask without problems and a 24" monitor. From the available options this is the best choice.

Answer:

False

Explanation:

The Carrier-sense multiple access with collision detection (CSMA/CD) technology was used in pioneer Ethernet to allow for local area networking.  Carrier-sensing aids transmission while the collision detection feature recognizes interfering transmissions from other stations and signals a jam. This means that transmission of the frame must temporarily stop until the interfering signal is abated.

The advent of Ethernet Switches resulted in a displacement of the CSMA/CD functionality.

Answer:

Explanation:

In programming an array is simply a grouping of various pieces of data. Various data elements are grouped together into a single set and saved into a variable. This variable can be called which would return the entire set which includes all of the elements. The variable can also be used to access individual elements within the set. In Java an example would be the following...

int[] myArray = {33, 64, 73, 11, 13};

In Java, int[] indicates that the variable will hold an array of integers. myArray is the name of the variable which can be called to access the array elements. The elements themselves (various pieces of data) are located within the brackets {}

A class may be a structured diagram that describes the structure of the system.  

It consists of sophistication name, attributes, methods, and responsibilities.  

A mailbox and an email message have certain attributes like, compose, reply, draft, inbox, etc.

Software architecture affects:

Performance, Robustness, Distributability, Maintainability.  

Explanation:

See attachment for the Model object classes which may be utilized in the system implementation to represent a mailbox and an email message.

Advantages:

Large-scale reuse Software architecture is vital because it affects the performance, robustness, distributability, and maintainability of a system.

Individual components implement the functional system requirements, but the dominant influence on the non-functional system characteristics is that the system's architecture.

Three advantages of System architecture:

• Stakeholder communication: The architecture may be a high-level presentation of the system which will be used as attention for discussion by a variety of various stakeholders.

• System analysis: making the system architecture explicit at an early stage within the system development requires some analysis.

• Large-scale reuse:

An architectural model may be a compact, manageable description of how a system is organized and the way the components interoperate.

The system architecture is usually an equivalent for systems with similar requirements then can support large-scale software reuse..

Answer:

B. Parallel

Explanation:

When using the ohmmeter function of a digital multimeter, the leads are placed parallel to the component being tested. The digital multimeter is placed parallel to the component because, current has to flow into the component so as to be able to measure its resistance. Without the flow of current in the component, the resistance could not be measured.

If the component were placed in series, there would be no way to close the circuit because, we need a closed circuit so as to measure the resistance and use the ohmmeter function of the digital multimeter.

Only a parallel connection would close the circuit.

So, B is the answer.

Answer:

The observed issues in data integration include the following from the listed options:

Two different databases may have different column names for the same actual information (e.g. customer ID vs customer-id).

There may be discrepancies between entries in two different databases for the same actual real-life entity (e.g. for an employee).

Explanation:

Data integration aims at consolidating data from disparate sources into a single dataset provide users with consistent access to data that will meet their various needs.  However, the process of data integration faces many challenges.  One of the challenges is disparate data formats and sources.  There is also the velocity or speed at which data are gathered.  For successful data integration, the different datasets need to be cleaned and updated with quality data.

Full question:

Provide the EXACT C++ line of code necessary to return the heap-dynamic variable ptr to the operating system.

Pokemon *ptr;

ptr = new Pokemon[6];

Answer:

delete ptr;

Explanation:

The command in the answer above deallocates memory(preventing memory leaks) and returns control to the operating system.

The command in the question dynamically allocates memory to the the heap(dynamically allocated memory is called heap) while the program is running(different from statically allocated memory that allocates before program compiles). When the variable is no longer needed, deallocation occurs using the command in our answer where the variable is deleted using the pointer(keeps track of dynamic variables).

Explanation:

Answer:

The program in Java is as follows:

import java.util.*;

public class Main {

public static void removeDuplicate(ArrayList<Integer> list){

 ArrayList<Integer> newList = new ArrayList<Integer>();

 for (int num : list) {

  if (!newList.contains(num)) {

   newList.add(num);  }  }

 for (int num : newList) {

     System.out.print(num+" ");  } }

public static void main(String args[]){

 Scanner input = new Scanner(System.in);

 ArrayList<Integer> list = new ArrayList<Integer>();

 System.out.print("Enter ten integers: ");

 for(int i = 0; i<10;i++){

     list.add(input.nextInt());  }

 System.out.print("The distinct integers are: ");

 removeDuplicate(list);

}}

Explanation:

This defines the removeDuplicate function

public static void removeDuplicate(ArrayList<Integer> list){

This creates a new array list

 ArrayList<Integer> newList = new ArrayList<Integer>();

This iterates through the original list

 for (int num : list) {

This checks if the new list contains an item of the original list

  if (!newList.contains(num)) {

If no, the item is added to the new list

   newList.add(num);  }  }

This iterates through the new list

 for (int num : newList) {

This prints every element of the new list (At this point, the duplicates have been removed)

     System.out.print(num+" ");  } }

The main (i.e. test case begins here)

public static void main(String args[]){

 Scanner input = new Scanner(System.in);

This declares the array list

 ArrayList<Integer> list = new ArrayList<Integer>();

This prompts the user for ten integers

 System.out.print("Enter ten integers: ");

The following loop gets input for the array list

 for(int i = 0; i<10;i++){

     list.add(input.nextInt());  }

This prints the output header

 System.out.print("The distinct integers are: ");

This calls the function to remove the duplicates

 removeDuplicate(list);
