Explain demand paging with a proper example

Answers

Answer 1
Demand paging :

In computer operating systems, demand paging (as opposed to anticipatory paging) is a method of virtual memory management. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it and that page is not already in memory (i.e., if a page fault occurs). It follows that a process begins execution with none of its pages in physical memory, and many page faults will occur until most of a process's working set of pages are located in physical memory. This is an example of a lazy loading technique.

A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm ships cartons of milk to a local grocery store. The cost of producing one liter of milk and the profit of each carton of milk vary from farm to farm. Write a program that prompts the user to enter: The total amount of milk produced in the morning. The cost of producing one liter of milk. The profit on each carton of milk. The program then outputs: The number of milk cartons needed to hold milk. Round your answer to the nearest integer. The cost of producing milk. The profit for producing milk.

Answers

Answer:

milk_produced = float(input("Enter the total amount of milk produced in the morning: "))

liter_cost = float(input("Enter the cost of producing one liter of milk: "))

carton_profit = float(input("Enter the profit on each carton of milk: "))

carton_needed = round(milk_produced / 3.78)

cost = milk_produced * liter_cost

profit = carton_profit * carton_needed

print("The number of milk cartons needed to hold milk is " + str(carton_needed))

print("The cost of producing milk is " + str(cost))

print("The profit for producing milk is " + str(profit))

Explanation:

*The code is in Python.

Ask the user to enter milk_produced, liter_cost and carton_profit

Calculate the number of milk cartons needed, divide the milk_produced by the capacity (3.78) of a cartoon and round the result

Calculate the cost, multiply the milk_produced by liter_cost

Calculate the profit, multiply the carton_profit by carton_needed

Print the results

C# The video game machine at your local arcade output coupons according to how well you play the game. You can redeem 10 coupons for a candy bar or 3 coupons for a gumball. You prefer candy bars to gumballs. Write a program that defines a variable initially assigned to the number of coupons you win. Next, the program should output how many candy bars and gumballs you can get if you spend all of your coupons on candy bars first, and any remaining coupons on gumballs.

Where is a good place to put that variable? 2) When an h file mentions another class, what is that called? (When a cpp file needs to use a class, they include it. This is an h file just mentioning a class, like it has a pointer of that type. You are promising the compiler that the class is in another file.) 3) What is a good guideline for deciding you must write a copy constructor, an assignment operator, and a destructor? 4) void Rock::Func( const Rock & X){} What is that argument type called and what does it do? 5) We saw overloading the = sign. How do you declare a class wanting to override the parenthesis operator?

Answers

Answer:

The counter variable for the sheep count should be declared and initialized before the constructor in the class. The extern keyword should be used to declare the class in the receiving C source file. A constructor is defined when there is a need to instantiate an object with an argument and an assignment operator is used to initialize a variable. The const keyword is used to specify a variable whose value should not change during the course of the program execution.

_________ attacks are becoming less common in modern operating systems.
a. Denial of service
b. SYN flood
c. Buffer overflow
d. None of the above

Answers

Answer:

c. Buffer overflow

Explanation:

In Computer programming, buffer can be defined as an area of memory set aside specially and specifically for holding data or informations.

A type of exploit that relies on overwriting contents of memory to cause unpredictable results in an application is known as buffer overflow. This ultimately implies that, buffer overflow is the process of exceeding the storage capacity of a memory buffer with data, beyond the amount it is designed to hold and therefore overwrites any adjacent memory locations.

Buffer overflow attacks are becoming less common in modern operating systems because the modern operating system usually leaves a space between buffers and randomize the layout of memory through call mapping, as well as through the use of runtime protection.

Using computer software, compare the 2016 year-to-date sales through February to the 2017 year-to-date sales through February for each manufacturer by computing the difference. Using computer software, sort the list of the manufacturers in order of largest to smallest difference in year-to-date sales. Which manufacturers are in the top five with increased sales

Answers

Incomplete question. Here's a similar question found in the attachments.

Answer:

General Motors Corp, Chrysler, Ford Motor Company, Toyota Motors sales USA Inc, Nissan North America Inc.

Explanation:

By, using the MS Excel computer software, you would be able to compare the 2016 year-to-date sales through February 2017 year-to-date sales for each manufacturer.

Simply copy the data into the data cells of MS Excel, next use the =sum formula (which should have a minus sign; For example, =SUM (B5 - E5) would give you the difference between the 2016 sales and 2017 sales, only if sales for 2016 is found in column B row 5 and sales for 2017 in column E row 5).

Thus, the results obtained can further be evaluated to determine the manufacturers in the top five with increased sales.

Input a double and print the first two digits after the decimal point with a space between them. Sample run: Please input a decimal number: 57.8934 Answer: 8 9 Hint - to complete the second coding activity in lesson 5 you had to learn how to get individual digits from an int value. You can reuse this method once you convert the user input to an appropriate int value (you will need both multiplication and casting for this).

Answers

Answer:

number = float(input("Please input a decimal number: "))

number = int (number * 100)

second_digit = number % 10

first_digit = int(number / 10) % 10

print("Answer: " + str(first_digit) + " " + str(second_digit))

Explanation:

Ask the user to enter a decimal number (number = 57.8934)

Multiply it by 100 (number = 5789.34) and typecast to int (number = 5789)

Use the module to get the second digit (9)

Divide the number by 10 (578.9), typecast to int (578) and use module operator to get the first digit (8)

Print the numbers as requested

The code is:

int main(){

double n;

int v, d;

scanf("%lf\n", &n);

n = n*10;

v = (int)n;

d = v%10;

printf("The first digit is %d\n", d);

n = n*10;

v = (int)n;

d = v%10;

printf("The second digit is %d\n", d);

return 0;

}

----------------------

To get each decimal digit, we multiply by 10 until the digit, then calculate the remainder of the operation(mod) of the integer part relative to 10.For example:

57.8934 x 10 = 578.934

The integer part is 578.

The remainder of the division of 578 by 10 is 8.

Now, we have to generalize it, thus:

int main(){

double n;

int v, d;

scanf("%lf\n", &n); -> Reads the double;

/*First digit*/

n = n*10; -> Multiplies by 10.

v = (int)n; -> Casts the integer part

d = v%10; 0 -> Remainder relative to 10 to get the first digit.

printf("The first digit is %d\n", d);

/*Second digit -> Does the same thing*/

n = n*10; -> Multiplies by 10.

v = (int)n; -> Casts the integer part

d = v%10; 0 -> Remainder relative to 10 to get the first digit.

printf("The second digit is %d\n", d);

return 0;
