Answer:

a. modern disks do not disclose the physical location of logical blocks.

Explanation:

In modern disks, the disk scheduling algorithms are built in the disk drive. It is difficult for operating system to schedule for improved rotational latency. All scheduling algorithms are forced to behave the same because operating system may have constraints. Disks are usually accessed in physical blocks. Modern disks put more electronic controls on the disk.

C++
vichka [17]

Answer:

#include <iostream>

#include <map>  

using namespace std;

int main()

{

   map<int, int> numbers;

   cout << "Enter numbers, 0 to finish" << endl;

   int number;

   while (true) {

       cin >> number;

       if (number == 0) break;

       numbers[number]++;

   }

   for (pair<int, int> element : numbers) {

       std::cout << element.first << ": occurs " << element.second << " times" << std::endl;

   }

}

Explanation:

One trick used here is not to keep track of the numbers themselves (since that is not a requirement), but start counting their occurrances right away. An STL map< > is a more suitable construct than a vector< >.

Programming challenge description: Write a program that, given two binary numbers represented as strings, prints their sum in bi
Lubov Fominskaja [6]

Answer:

The program to this question can be given as:

Program:

#include<iostream>  //include header file

using namespace std;  

string add(string a, string b)  //define add function

{       //declare variable  

   string result = "";  

   int sum = 0,k,l;      

   cahr x;    

   k= a.size() - 1;

   l = b.size() - 1;  

   while (k>= 0 || l>= 0 || sum == 1) //loop

   {

   //addition 

       sum= sum+ ((k >= 0)? a[k] - '0': 0);  

       sum= sum+ ((l >= 0)? b[l] - '0': 0);

        x=sum%2;

      result=(x+'0') +result;

  // Compute carry

       sum =sum/ 2;  

       // Move to next digits  

       k--;  

       l--;  

   }  

   return result; //return value

}

int main()  //main method  

{  

   string a,b;  //string variable

   cout<<"Enter first binary digit: ";  //message.

   cin>>a;     //input from user

   cout<<"Enter Second binary digit: ";  //message.

   cin>>b;     //input from user

   cout <<"Addition :"<<add(a, b)<<endl; //print addition

   return 0;  

}

Output:

Enter first binary digit: 1101

Enter Second binary digit: 100

Addition :10001

Explanation:

In the above c++ program first, we include the header file. Then we define the add function in the add function we add two binary digits by passing value as arguments. In this function, we define a variable that is used on the addition of binary numbers. In this function we define the loop in the loop we check if two binary number is 1 then it will print 0 and pass 1 as the carry. after performing addition it will return value. In the main function, we take two binary numbers from the user and pass the value to the function and print function return value.

What are the oop concept of java
mash [69]

Answer: OOP concepts in Java are the main ideas behind Java’s Object Oriented Programming. They are abstraction, encapsulation, inheritance, and polymorphism. Grasping them is key to understanding how Java works. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security.
