Explain working principle of computer.​

Explanation:

The working principle of the computer system. Computers do the work primarily in the machine and we can not see, a control center that converts the information data input to output. This control center, called the central processing unit (CPU), How Computers Work is a very complex system.

Which of the following best explains how an analog audio signal is typically represented by a computer?
a. An analog audio signal is measured at regular intervals. Each measurement is stored as a sample, which is represented at the lowest level as a sequence of bits.
b. An analog audio signal is measured as a sequence of operations that describe how the sound can be reproduced. The operations are represented at the lowest level as programming instructions.
c. An analog audio signal is measured as input parameters to a program or procedure. The inputs are represented at the lowest level as a collection of variables.
d. An analog audio signal is measured as text that describes the attributes of the sound. The text is represented at the lowest level as a string.

Create a PetStore class, a Dog class, and Cat class. Once instantiated, a PetStore should be able to take in and give out pets. The store's method for receiving pets should be called receive. This method should take a single pet object (either a Dog or Cat instance) and should add it to the store's inventory of pets. The store's method for giving out a pet should be called sell and can take no arguments. The method returns a pet when called.

Implement the function _isPalindrome() in palindrome.py, using recursion, such that it returns True if the argument s is a palindrome (ie, reads the same forwards and backwards), and False otherwise. You may assume that s is all lower case and doesn’t include any whitespace characters.

Create a class named TriviaGameV1 that plays a simple trivia game. The game should have five questions. Each question has a corresponding answer and point value between 1 and 3 based on the difficulty of the question. TriviaGameV1 will use three arrays. An array of type String should be used for the questions. Another array of type String should be used to store the answers. An array of type int should be used for the point values. All three arrays should be declared to be of size 5. The index into the three arrays can be used to tie the question, answer, and point value together. For example, the item at index 0 for each array would correspond to question 1, answer 1, and the point value for question 1. Manually hardcode the five questions, answers, and point values in the constructor of TriviaGameV1. The five questions and their corresponding answers are shown on page 3. The point values should be set to 1, 2, 2, 3, 1, respectively.

The class should also provide the following two public methods:

• public boolean askNextQuestion() - This method takes no argument and returns a boolean. If there are no more questions to ask, it returns false. Otherwise, it asks the next question and gets an answer from the user. If the player’s answer matches the actual answer (case insensitive comparison), the player wins the number of points for that question. If the player’s answer is incorrect, the player wins no points for the question and the method will show the correct answer. It returns true after Q & A have been processed.
• public void showScore() - This method takes no argument and returns void. It displays the current score the player receives thus far.

The test driver is provided below, which creates a TriviaGameV1 object. After the player has answered all five questions, the game is over.

public class TriviaGameV1Test {
public static void main(String[] args) { TriviaGameV1 game = new TriviaGameV1();
while (game.askNextQuestion()) game.showScore(); System.out.println("Game over! Thanks for playing!"); }
}

The L-exclusion problem is a variant of the starvation-free mutual exclusion problem. We make two changes: as many as L threads may be in the critical section at the same time, and fewer than L threads might fail (by halting) in the critical section. An implementation must satisfy the following conditions:_____.
L-Exclusion: At any time, at most L threads are in the critical section.
L-Starvation-Freedom: As long as fewer than L threads are in the critical section, then some thread that wants to enter the critical section will eventually succeed (even if some threads in the critical section have halted).
Modify the n-process Bakery mutual exclusion algorithm to turn it into an L-exclusion algorithm. Do not consider atomic operations in your answer. You can provide a pseudo-code solution or written solution.

Create an application containing an array that stores eight integers. The application should call five methods that in turn:
Display all the integers
Display all the integers in reverse order
Display the sum of the integers
Display all values less than a limiting argument
Display all values that are higher than the calculated average value.
public class ArrayMethodDemo {
public static void main (String args[]) {
int[] numbers = {12, 15, 34, 67, 4, 9, 10, 7};
int limit = 12;
display(numbers);
displayReverse(numbers);
displaySum(numbers);
displayLessThan(numbers, limit);
displayHigherThanAverage(numbers);
}
public static void display(int[] numbers) {
// Write your code here
}
public static void displayReverse(int[] numbers) {
// Write your code here
}
public static void displaySum(int[] numbers) {
// Write your code here
}
public static void displayLessThan(int[] numbers, int limit) {
// Write your code here
}
public static void displayHigherThanAverage(int[] numbers) {
// Write your code here
}
}

3.4 code practice question 2 edhesive

A field is a group of related records that can be identified by the user with a name, type, and size.

C++ coding, help
In this program you will be reading numbers from a file. You will validate the numbers and calculate the average of all of the valid numbers.
Your program will read in a file with numbers. The numbers will be of type double.
The numbers should be in the range from 0 to 110 (inclusive). You need to count all of the numbers between 0 and 110. You also need to calculate the average of these numbers.
If a number is not valid (that is, it is less than 0 or greater than 110) you need to count it (as a count of invalid values) and you need to write out the number to a file called "invalid-numbers.txt". Values written to file invalid-numbers.txt should be in fixed format with two digits to the right of the decimal point.
As you did in lab lesson 7 part 1 you need to read in the input file name using cin.
The output from your program will be written to cout. The output must contain the file being processed, the total number of values read in from the file, the number of invalid values read in, the number of valid values read in.
The last thing you need to output is either the average of the valid values or an error message. The average must have two digits of precision to the right of the decimal point and must be in fixed format. If there is not valid average you should output the message:
An average cannot be calculated
In what case would you display this message?
If the input file cannot be opened, you will need to output a message. Assume the input file name is badinput.txt and it cannot be opened. You will display the following error message to cout
File "badinput.txt" could not be opened
Here is an example of a working program:
Assume the file name read in from cin is:
input.txt
and that input.txt contains:
-12
0
98.5
100
105.5
93.5
88
75
-3
111
89
-12
Your program would output the following:
Reading from file "input.txt"
Total values: 12
Invalid values: 4
Valid values: 8
Average of valid values: 81.19
The contents written out to file invalid-numbers.txt are:
-12
-3
111
-12
You are reading from an input file and you are writing to an output file. Make sure you close both files after you are finished using them. You must do this in your program, you cannot just let the operating system close the files for you.
For tests where there is output written to an output file the contents of the output file will determine if you passed that test or not. For cases where you have written out to cout the tests will check the output sent to cout. In some cases output will be written to a file and to cout. When this is the case the test will be run twice with the same input. Once to test cout and once to test the contents of the output file. An example of this would be tests 2 and 3. Both use the same input file. Test 2 check the output written to cout and test 3 checks the output written to the file invalid-numbers.txt.

You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???

Along with the encrypted copy, some mysterious person has also given you the following documents:

helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.

hints.txt -- Seems important.

In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:

decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")

Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).

Hint: The penny math lecture is here.

Another hint: Don't forget about while loops...
