Answer:
The C++ code is given below with appropriate comments
Explanation:
//Remove this header file if not using visual studio.
#include "stdafx.h"
//Include the required header files.
#include <iostream>
//Use for maths function.
#include <cmath>
using namespace std;
//Define main function
int main()
{
// Define the variables
double targetValue = 0.3333;
double sensorReading = 0.0;
//Perform the opeartion.
sensorReading = 1.0 / 3.0;
// Get the absolute floating point value and
// Check up to 4 digits.
if (fabs(sensorReading - targetValue) < 1E-4)
{
//Print equal if the values are close enough.
cout << "Equal" << endl;
}
else
{
//Print not equal if the values are not
//close enough.
cout << "Not equal" << endl;
}
system("pause");
//Return the value 0.
return 0;
}
Answer:
D) extents
Explanation:
Disks fragmentations in computer science refers to the cases of a file system laying out its contents in a non-continuous manner thus preventing an in-place alteration of the contents (that is the contents of the file are scattered in fragments across different location on the disk). Disk fragmentation is mostly associated with aging. To mitigate against this, modern implementation of file systems try to preallocate longer chunks of disk space, this is called extents, in this way fragmentation is avoided since a contiguous size of disk space is preallocated to the files and its contents stay together.
The difference between the new and open commands on the file menu are quite simple. The new command creates a brand new file, while the open command opens a file that already exists or has been created.
Answer: Medium Dependent Interface Crossover (MDIX)
Explanation:
The technology that is typically implemented on switches to avoid Ethernet connectivity problems is Medium Dependent Interface Crossover(MDIX) For switches with Auto (MDIX) the connection is configured automatically and a crossover or straight-through cable can be used to connect two switches. When this MDIX interface is connected it corrects the connectivity speed and the cabling for proper device functionality.
