For which two reasons might a designer use contrasting colors on a web page?

Answer: Dereferencing a variable that is not a pointer

Explanation:

The execution time also refered to as the CPU time pertaining to a given task is the time that is used by the system to execute a task.

Some of the reasons for a fatal execution-time error include:

• Dereferencing a pointer that has not been initialized properly

• Dereferencing a null pointer

• Dereferencing a pointer that has not been assigned to point to a specific address.

It should be noted that dereferencing a variable that is not a pointer doesn't cause a fatal execution-time error.

Compute Units

Explanation:

A platform can be defined as a computing environment for building and executing sets of code in a software application or program such as an application programming interface (API).

The two parts of the platform used to run an application software are both hardware and software (operating system).

Machine and assembly are referred to as a low level programming language used in writing software programs or applications with respect to computer hardware and architecture. Machine language is generally written in 0s and 1s, and as such are cryptic in nature, making them unreadable by humans but understandable to computers.

OpenCl is an abbreviation for open computing language that runs on CUDA-powered graphics processing units (GPUs). An OpenCL Device is composed of compute units and an OpenCl compute unit typically comprises of processing elements.

Explanation: When it comes to research papers your topic shouldnt be too broad. Your topic should be broad enough you can find a good amount of information but not too focused that you can't find any information.

Answer:

The program is as follows:

import java.util.*;

public class Main{

public static void backward(int [] Rndarray, int lnt){

    System.out.print("Reversed: ");

    for(int itm = lnt-1;itm>=0;itm--){

        System.out.print(Rndarray[itm]+" ");     } }

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 int lnt = input.nextInt();

 Random rd = new Random();

 int [] Rndarray = new int[lnt];

 for (int itm = 0; itm < lnt; itm++) {

        Rndarray[itm] = rd.nextInt();

        System.out.print(Rndarray[itm]+" ");

     }

     System.out.println();

 backward(Rndarray,lnt); }}

Explanation:

This defines the backward() method

public static void backward(int [] Rndarray, int lnt){

This prints string "Reversed"

    System.out.print("Reversed: ");

This iterates through the array

    for(int itm = lnt-1;itm>=0;itm--){

Each element is then printed, backwards

        System.out.print(Rndarray[itm]+" ");     } }

The main begins here

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

This gets the array length

int  n = input.nextInt();

This creates a Random object

Random rd = new Random();

This declares the array

 int [] Rndarray = new int[lnt];

This iterates through the array for input

 for (int itm = 0; itm < lnt; itm++) {

This generates a random number for each array element

        Rndarray[itm] = rd.nextInt();

This prints the generates number

        System.out.print(Rndarray[itm]+" ");

     }

This prints a new line

     System.out.println();

This passes the array and the length to backward() method

 backward(Rndarray,lnt); }}

//class declaration

public class Rectangle{

   //declare the instance variables - width and height

   double width;

   double height;

   //the constructor

  public Rectangle(double width, double height){

       //initialize the width of the rectangle

       this.width = width;

       //initialize the height of the rectangle

      this.height = height;

   }

   //method get_perimeter to compute the perimeter of the rectangle

   public double get_perimeter(){

       //compute the perimeter

       //by using the formula 2(width + height)

      double perimeter = 2*(this.width + this.height);

       //return the perimeter

       return perimeter;

   }

   //method get_area to compute the area of the rectangle

   public double get_area(){

       //compute the area

       //by multiplying the width and height of the rectangle

       double area = this.width * this.height;

       //return the area

      return area;

   }

   //method resize to resize the rectangle

   public void resize(double factor){

       //resize the width of the rectangle

       //by multiplying the width by the factor

       this.width = this.width * factor;

       //resize the height of the rectangle

       //by multiplying the height by the factor

      this.height = this.height * factor;

   }

}  //end of class declaration

Given - When adding several user accounts, you might want to use the new users utility, which can process a text file full of entries to add user accounts.

To find - Use the man or info page to find out how to use this utility, and use it to add three users.

Proof -

New Users Utility:

It is an utility which reads the file full of usernames and clear text passwords.

It then uses this information to update a group of the existing users to create new users.The format of the file consists of specified things like:

pw - passwd

pw - age

pw - gid

pw - dir

Use of the Utility:

The command is new users filename

The file should look like -

(Username : Password : UID : GID : User Information : Home Directory : Default Shell)

where ,

UID = User Identifier

GID = Group Identifier

Testing the Users:

Creating users from the file given above test User 1, directory Of File

Executing the create user new users directory Of File

Repeat this step to undergo all the users that are been noted down in the file to make them a user in the noted group policy.

Hence,

These are the steps of using the new Users utility.

Answer:

An object is an abstract data type with the addition of polymorphism and inheritance. Rather than structure programs as code and data, an object-oriented system integrates the two using the concept of an "object". An object has state (data) and behavior (code). Objects can correspond to things found in the real world.

Answer:

Serverless computing.

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Platform as a Service (PaaS).

2. Infrastructure as a Service (IaaS).

3. Software as a Service (SaaS).

The three (3) main characteristics of cloud computing are;

I. Measured service: it allows cloud service providers to monitor and measure the level of service used by various clients with respect to subscriptions.

II. Resource pooling: this allows cloud service providers to serve multiple customers or clients with services that are scalable and provisional.

III. Elasticity: this is the ability of the cloud computing service to be flexible and adaptive to the traffic or requests from the end users.

Serverless computing is a term which refers to a cloud-native and streamlined technology that is designed typically for hosting cloud-based applications, in which a server operates for short bursts only when needed by an application or service. Serverless computing is used for the allocation of machine resources on demand.

Answer:

A solution is a mixture in which the particles are so small that the components are indistinguishable from each other. The amount of the solute and the solvent in a solution can be expressed in terms of different concentration expressions such as molarity, morality, etc.

Explanation:

To calculate the number of moles of sodium carbonate, the volume in liters will be multiplied by the molar concentration of the solution.

moles Na2CO3 = 2.0 M  x 0.0100 L = 0.020 moles Na2CO3

Hope it helps :)

Answer:

There are 20. mol of Na2CO3 in 10.0L of 2.0M solution.

Explanation:

Molarity is represented by this equation:

(look at attachment)

In our case, we already have the molarity and volume of solution, both of which have good units.

Let's rearrange the equation to solve for the number of moles. We can do this by multiplying by L solution on both sides of the equation. The L solution will cancel out on the right side, leaving the number of moles being equal to the molarity times volume:

Moles of solute

=Lsolution×Molarity

Now we just plug the known values in!

Moles of solute = (10.0 L) (2.0M) = 20. moles

Answer: CTRL + C or copy and paste

Explanation: to copy and paste highlight text by dragging mouse or clicking on touchpad and holding over selected text, if not on a computer but on a touch screen device ( ex: Phone, iPad etc) hold down until it is blue use the tear drops from the top and bottom to highlight the text you need. Then hold down the blue area until options come up stop holding and select copy and then go to where you want to put the text and hold down again and select paste. If on computer drag cursor over text while holding down on left click or holding down on touchpad, it will highlight light blue then left click or click on the touchpad with both fingers and repeat the process of copying and pasting as said before.

Answer:

A)  i) starvation  ii) flow control

B) Network congestion

Explanation:

A) Network problems that can be addressed / solved

By replacing the workstations 100 Mbps switches with 1000 Mbps switches the problem of

Starvation;  been faced by the servers due to the delay in sending data to be processed by the servers from the workstations will be resolved .

Flow control : The huge difference in the speeds of the workstations and servers causes a network buffer which leads to packet loss therefore when the workstations 100 Mbps switch is replaced with 1000 Mbps switch this network problem will be resolved

b) The potential problem that can be encountered is Network Congestion

The following code is written in Java. It creates the UnknownOperatorException class and catches it if the user enters something other than the valid operators. If so it continues asking the user for a new input. Once a valid operator is entered, it exits the function and prints the operator.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       char symbol = askForOperand();

       System.out.println("Operand: " + symbol);

   }

   public static char askForOperand() {

       Scanner in = new Scanner(System.in);

       try {

           System.out.println("Enter operator symbol: ");

           char symbol = in.nextLine().charAt(0);

           if ((symbol != '-') && (symbol != '*') && (symbol != '/')) {

               System.out.println(symbol);

               throw new UnknownOperatorException();

           } else {

               return symbol;

           }

       } catch (NumberFormatException | UnknownOperatorException e) {

           System.out.println("Not a valid operand");

           char symbol = askForOperand();

           return symbol;

       }

   }

}

class UnknownOperatorException extends Exception {

   public UnknownOperatorException() {

       System.out.println("Unknown Operator");

Explanation:

1. Redundant batch of Inexpensive Drives (or Disks) (RAID) is a term for data storage schemes that divide and/or replicate data amid multiple hard drives.

2. RAID can be designed to provide increased data accuracy or increased Input/Output performance

Hardware RAID exists as a customized processing system, utilizing various controllers or RAID cards to control the RAID design independently from the OS. Software RAID utilizes the processing capacity of that computer's operating system in which the RAID disks exists installed.

We have two kinds of RAID implementation through. Hardware and Software. Both these implementation contains its own benefits and drawbacks.

Software RAID does not count any cost for a RAID controller and exists fairly effortless to estimate the cost of as you exist only buying additional drives. All of our usual dedicated servers come with at least two drives, indicating there exists NO cost for software RAID 1, and stands positively suggested.  It exists positively suggested that drives in a RAID array be of the exact type and size. With RAID 0 or RAID 1, you'd require at least two drives, so you would require to buy one additional drive in most cases. With RAID 5 you'll require at least three drives, so two additional drives, and with RAID 6 or 10 you'd require at least four total drives. To earn additional implementation, redundancy, or disk space, you can count more disks to the collections as well.
