g You and your friend both send documents to the printer, but the printer can only print one document at a time. What does it do with the other document
Answer:
It places the document in a buffer
Explanation:
Since the printer can only print a document at a time, the other document is going to be placed in a buffer.
The print buffer can be described as a location in memory that has the function of holding data that is going to be sent to a computers printer. A print job such as in this scenario may remain in the buffer because another document is to be printed first.
Sometimes a document could be put in the buffer because the computer is waiting for the printer to respond. This is just another reason why documents are placed in a buffer.

Given two integer variables distance and speed, write an expression that divides distance by speed using floating point arithmetic, i.e. a fractional result should be produced.
1. Calculate the average (as a double) of the values contained in the integer variables num1, num2, num3 and assign that average to the double variable avg. Assume the variables num1, num2, and num3 have been declared and assigned values, and the variable avg declared.
Creating objects
2. Declare a reference variable of type File named myFile.
3. Declare a variable named myMenu suitable for holding references to Menu objects.
4. Suppose a reference variable of type File called myFile has already been declared. Create an object of type File with the initial file name input.dat and assign it to the reference variable myFile.
invoking methods
Answer:
Following are the solution to this question:
Explanation:
In this question, the result value which would be produced are as follows:
[tex]= \frac{distance}{(double) \ speed}[/tex]
In point 1:
The formula for the avg variable:
[tex]\to avg = \frac{(num_1 + num_2 + num_3)}{(double)\ 3};[/tex]
In point 2:
The variable for the file is:
File myFile;
In point 3:
The variable for the mymenu:
Menu myMenu;
In point 4:
myString = new String();
Write a method called rotate that moves the value at the front of a list of integers to the end of the list. For example, if a variable called list stores the values [8, 23, 19, 7, 45, 98, 102, 4], then the call of list.rotate(); should move the value 8 from the front of the list to the back of the list, changing the list to store [23, 19, 7, 45, 98, 102, 4, 8]. If the method is called for a list of 0 elements or 1 element, it should have no effect on the list. You may neither construct any new nodes to solve this problem nor change any of the data values stored in the nodes. You must solve the problem by rearranging the links of the list.
Answer:
Explanation:
public void rotate()
{
if(front == null)
return;
ListNode current = front;
ListNode firstNode = current;
while(current.next != null)
{
current = current.next;
}
current.next = front;
front = firstNode.next;
firstNode.next = null;

How does a search engine use algorithms to provide search results?
by creating keywords and phrases
by recording and storing data for worldwide use
by retrieving and ranking relevant search results
by limiting the type of search terms that it will accept
Answer:
By retrieving and ranking relevant search results
Explanation:
A search engine use algorithms to provide search results by retrieving and ranking relevant search results. The correct option is c.
What is an algorithm?When a user enters a search query into a search engine, all of the sites that are considered relevant are pulled from the index and ranked in a set of results using a hierarchical algorithm.
Each search engine uses a different set of algorithms to determine which results are the most pertinent. Through tags like HREF and SRC, they may detect new links on these pages, and they add such pages to their list of sites to index.
Then, based on the search phrases you entered, search engines utilize their algorithms to produce a prioritized list from their index of the pages you should be most interested in.
Therefore, the correct option is c. by retrieving and ranking relevant search results

import java.util.Scanner;
public class U2_L3_Activity_Four{
public static void main(String[] args){
/* Write your code here */

if (c != ' '){
count++;
}
else{
break;
