In which order does the processor search computer memory when it requires instruction or data?

One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.

dsp73

The lamp and the ice bag were at the same place.
Sounds like the experiment was intended to show on a small scale ocean currents from the poles to the equator and back to the poles. The bag of ice would simulate the cold at the poles while the lamp would simulate the heat provided by the sun near the equator. With that in mind, let's look at the possible flaws and see what is likely.
Not enough ink was added.
* If you can see the ink, then there's enough ink. So this isn't the correct choice.
Not enough water was taken.
* Possibility there wasn't enough volume of water to setup a current, but not too likely since the baking dish was filled. So let's look further.
The dish was too small for the experiment.
* Same as above. It might be this, but there's something more likely.
The lamp and the ice bag were at the same place.
* This sounds like a winner. In the real world, the poles are cold and the equator gets more sunlight. So there's a temperature gradient. In the described setup, both the heat sink (the bag of ice) and the heat source (the lamp) were at the same location.

Describe the difference between the while loop and the do-while loop.

Karo-lina-s [1.5K]

Answer:

The difference between While loop and Do - While loop are explained below.

Explanation:

While loop : It is a looping procedure in which the statements inside the while loop are executed depending on the condition outside the while before starting the loop.
If the condition is true then the code inside loop is executed otherwise not.
Do - While loop: It is a looping procedure in which the statements inside the loop get executed and then the condition at the end of the loop is checked.
This means even the condition is fails the statements inside the loop are executed once.
Do while loop name itself suggests that "do the while and then check the condition".

Who conceptualizes the design and the working of a website

Citrus2011 [14]

Answer is "Web Designer".

Web Designers are the "artists" of the website. They conceptualize the layout and functionality of the site, from features to format. They may do little coding, and are mostly involved in the creative elements of web design. The Web Developer is less big-picture, and more knitty-gritty building of the website. She is the one who does the coding and actually builds the website, using the web designer's model.

Write code to take a String input from the user, then print the first and last letters of the string on one line. Sample run: En

Ainat [17]

<h2>Answer:</h2>

//import the Scanner class to allow for user input

import java.util.Scanner;

//Begin class definition

public class FirstAndLast{

//Begin the main method

public static void main(String []args){

//****create an object of the Scanner class.

//Call the object 'input' to receive user's input

//from the console.

Scanner input = new Scanner(System.in);

//****create a prompt to tell the user what to do.

System.out.println("Enter the string");

//****receive the user's input

//And store it in a String variable called 'str'

String str = input.next();

//****get and print the first character.

//substring(0, 1) - means get all the characters starting

//from the lower bound (index 0) up to, but not including the upper

//bound(index 1).

//That technically means the first character.

System.out.print(str.substring(0,1));

//****get and print the last character

//1. str.length() will return the number of character in the string 'str'.

//This is also the length of the string

//2. substring(str.length() - 1) - means get all the characters starting

// from index that is one less than the length of the string to the last

// index (since an upper bound is not specified).

// This technically means the last character.

System.out.print(str.substring(str.length()-1));

} // end of main method

} //end of class definition
