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.

How to Print output in JavaScript

Answers

If you want to print on a page you can use

document.write();

If you want to write in console then there are multiple options

console.log() - to log information

console.error();- to log errors

console.warn(); - to log warning message

If you want to popup some information the you can use -

alert(message);

there are also various options present in alert.

or

print() essentially just calls up the native print dialog for a given window.

But as you're are thinking, it will work on any window or (i)frame.

thus if you write content to a frame, you can then call this to print it.

window.frameName.print();

note the only drawback (and its a big one), is that this calls up the print dialog... not the print preview window... thus the user doesn't really get a chance to see what they are printing and/or scale it to fit their printer/paper.

I personally wish that all browsers would implement the following to handle the above issue.

window.printPreview();

Hope this will help !!!

b. Undocumented sources
c. Lack of search tools
d. Time-consuming searches
e. Unreliable conten

Answers

Answer:

b. d. e.

Explanation:

The web is a vast and endless database of information and has become an invaluable resource for research. That being said it can also bring with it many problems, the main one being unreliable content due to undocumented sources, false testimonies, information with no evidence, etc. The amount of false information on the internet can sometimes make it very time consuming since you have to take the extra step of verifying the information you come across. Despite this, the WEB has information on every topic including current news, and with the wide array of search tools available it is very easy to find what you are looking for.

Answers

Instructions
Currently, this program will add 6 and 3 together, output the math problem and output the answer. Edit this code so that a random number is generated from 1 - 10 (inclusive) for the variables a and b. Also, instead of adding the two numbers together, the edited program should multiply them, and output the proper math problem and answer. Be sure to update every line of code to reflect the changes needed. import random

Answers

Answer:

The original program is not given; So, I'll just write the program myself in python

import random

x = random.randint(1,10)

y = random.randint(1,10)

result = x * y

print(str(y)+" * "+str(x)+" = "+str(result))

Explanation:

The first line imports random

import random

The next two line generates random numbers between 1 and 10 and save in variables x and y

x = random.randint(1,10)

y = random.randint(1,10)

This line multiplies both numbers

result = x * y

This line prints the result

print(str(y)+" * "+str(x)+" = "+str(result))

The modified program written in python 3 is given below :

import random # import the random module for generating random numbers

a = random.randint(1, 11)#a random integer value between the values (1 and 10) is attached to variable a

b = random.randint(1,11)#a random integer value between the values (1 and 10) is attached to variable b

answer = a * b# multiplies the value of a and b and attach the result to the variable answer

print(str(a) + " * " + str(b) + " = " + str(answer))#displays the operation and result obtained as a string.

This question is incomplete, the complete question is;

The binary string 00100100 is a member of which of the following problems? Remember, a "problem" is a language whose strings represent the cases of a problem that have the answer "yes." In this question, you should assume that all languages are sets of binary strings interpreted as base-2 integers. The exception is the problem of finding palindromes, which are strings that are identical when reversed, like 00100100, regardless of their numerical value.

a) Is the given string a palindromes ?

b) Is the given string a perfect cube?

c) Is the given string greater than 50?

d) Is the given string even?

e) is the given string a perfect square?

Answer:

a) the given binary string is a palindromes

b) the given string is NOT a perfect cube

c) the given string is NOT greater than 50?

d) the given string is an even

e) the given string a perfect square

Explanation:

Given that;

binary string : 00100100

a)

Is the given string a palindromes ?

the given binary string = 00100100

now when you reverse the string, its still going to be : 00100100

so the given binary string is a palindromes

b)

Is the given string a perfect cube

the given string : 00100100 = 36

now 2^3 = 8,

3^3 = 27,

4^3 = 64

so 36 is not a perfect cubic

hence the given string is NOT a perfect cube

c)

Is the given string greater than 50?

the given string : 00100100 = 36

and 36 < 50

so the given string is NOT greater than 50?

d)

Is the given string even?

the given string  : 00100100 = 36

and 36 can be divided exactly by 2

so the given string is an even

e)

is the given string a perfect square?

the given string  : 00100100 = 36

now 6^2 = 36  i.e 6 multiply by 6 = 36

therefore the given string a perfect square
