. A file allocation table (FAT) is used to keep track of the portions assigned to a file. Select one: True False

Answers

Answer 1
Answer:

Answer: True

Explanation: File allocation table(FAT) is the part of the file system that helps the hard drives .It is used for the management of the files and data which gets stored in the hard drive  by the operating system. It can also help in the extension or expansion of the hard drive storage.

It also keeps tracing the files and data accordingly. This table works for the  portable devices ,cameras etc. Thus, the statement given is true.

Explanation:

what would be the address of the cell, which is intersect of the second row and third column in a worksheet

Answers

Answer: The address of the cell is C2

Explanation:

In a worksheet like Microsoft Excel, there are rows and columns. It tags rows with numbers and tags columns with alphabet letters. For example, the first row is 1, the second row is 2, the third row is 3, and so on. Similarly, the first column is A, the second column is B and so on.

We want to know the address for the intersect of the second row i.e. 2, and the third column i.e. C in a worksheet. In other words, it might intersect column C and row 2.

A cell is a box where a row and column intersect. The address of the cell starts with the column, and next there is the row. In that case, we can conclude that the address of the cell is C2.

C2 or B3. This is if you are talking about Microsoft Excel.

(1) Prompt the user to enter a string of their choosing. Output the string. Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself.
(2) Complete the GetNumOfCharacters() function, which returns the number of characters in the user's string. Use a for loop in this function for practice. (2 pts)
(3) In main(), call the GetNumOfCharacters() function and then output the returned result. (1 pt) (4) Implement the OutputWithoutWhitespace() function. OutputWithoutWhitespace() outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the OutputWithoutWhitespace() function in main(). (2 pts)
Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Number of characters: 46 String with no whitespace: The only thing we have to fear is fear itself.

See solution below

See comments for explanations

Explanation:

import java.util.*;

class Main {

 public static void main(String[] args) {

   //PrompT the User to enter a String

   System.out.println("Enter a sentence or phrase: ");

   //Receiving the string entered with the Scanner Object

   Scanner input = new Scanner (System.in);

   String string_input = input.nextLine();

   //Print out string entered by user

   System.out.println("You entered: "+string_input);

   //Call the first method (GetNumOfCharacters)

   System.out.println("Number of characters: "+ GetNumOfCharacters(string_input));

   //Call the second method (OutputWithoutWhitespace)

   System.out.println("String with no whitespace: "+OutputWithoutWhitespace(string_input));

   }

 //Create the method GetNumOfCharacters

   public static int GetNumOfCharacters (String word) {

   //Variable to hold number of characters

   int noOfCharactersCount = 0;

   //Use a for loop to iterate the entire string

   for(int i = 0; i< word.length(); i++){

     //Increase th number of characters each time

     noOfCharactersCount++;

   }

   return noOfCharactersCount;

 }

 //Creating the OutputWithoutWhitespace() method

 //This method will remove all tabs and spaces from the original string

 public static String OutputWithoutWhitespace(String word){

   //Use the replaceAll all method of strings to replace all whitespaces

   String stringWithoutWhiteSpace = word.replaceAll(" ","");

   return stringWithoutWhiteSpace;

 }

Which file is used to configure the various mounting options of a filesystem upon boot?a. /etc/mount
b. /etc/fstab
c. /var/filesystem
d. /boot/config

Answers

Answer:

B. /etc/fstab file.

Explanation:

The /var/filesystem file is a subdirectory of the root directory of a linux operating system, used to store files during the operation of a computer system.

The /boot/config file is  a file directory used to store system configuration parameters which can be accessed by the GPU before the installation of the ARM CPU and linux.

The /etc/mount (or /etc/mtab) and /etc/fstab are used to show the list of mounted volumes. The /etc/mtab gives details of already mounted volumes, but the /etc/fstab shows the list of possible volumes to be mounted upon the boot of the system.

Most networking media send data using _____ in which data is represented by only two discrete states: 0s and 1s.A. digital signals

B. contiguous signals

C. ramp signals

D. exponential signals

Answers

Answer: A) Digital signals

Explanation:

  • Digital signal is a signal that helps in describing about the data in sequential manner in form discrete bands or binary values.
  • The electrical signal containing data is converted into bits that can be represented through two digital values i.e. 0s and 1s.
  • Other options are incorrect because contiguous signal is regular adjacent signal. Ramp signal is represented as increment in magnitude with time
  • Exponential signal is based on sine and cosine signal that is two real time signal.
  • Thus, the correct option is option(A).

Answer:

i think digital signals

Explanation:

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values.[1][2][3] This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.
