Answer:
Holographic data storage.
Explanation:
Traditional storage devices like the hard disk and CD ROM make use of magnetic and optical processes to store a bit at a time in various locations on the disk. The holographic storage uses light wave at many angles to store multiple bits of data in parallel in the same location.
The holographic storage is very fast in reading and writing millions of data bits at a time because of its parallel nature, making it the fastest data storage device.

I wish I could answer your question, but I believe that is no English.
Explanation:
Answer:
// here is code in C++(bmi.cpp).
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
float weight,height;
cout<<"enter the weight(in kilograms):";
//read the weight
cin>>weight;
cout<<"enter the height(in meters):";
//read the height
cin>>height;
// calculate the bmi
float bmi=weight/(pow(height,2));
// print the body-mass index with two decimal places
cout<<"BMI is: "<<fixed<<setprecision(2)<<bmi<<endl;
return 0;
}
Explanation:
Read the weight from user and assign it to variable "weight",read height and assign it to variable "height".Then find the body-mass index as (weight/height^2).Here weight should be in kilograms and height should be in meters.
Output:
enter the weight(in kilograms):75
enter the height(in meters):1.8
BMI is: 23.15
Answer:
An operating system is the primary software that manages all the hardware and other software on a computer. The operating system, also known as an “OS,” interfaces with the computer’s hardware and provides services that applications can use.
