Answer:
The exec command by interpreter to start new process
Explanation:
On Unix systems, a call to the fork system must be made followed by a call to the e x e c system to begin a new process. The fork call clones the process that is currently running, while the executive call overlays a new process based on a different executable over the calling process.
It is seperate from Kernal because
It Read user commands or a script and execute them, generally turning them into one or more system calls. Is usual It is not part of the kernel since the command interpreter is subject to change.
Answer:
#include <stdio.h>
int main() {
const float square_feet;
printf("Enter area in square feets: ");
// reads and stores input area
scanf("%f", &square_feet);
float acres= square_feet/43560;
// displays area in acres
printf("area in acres is: %.2f", acres);
return 0;
}
Explanation:
code is in C language.
double slashed '//' lines are not code but just comments to understand what it mean in code or for explanation purpose
Answer:
The process of converting information, such as text, numbers, photos, or music, into digital data that can be manipulated by electronic devices is called Digitization
Explanation:
It is the process of converting “information in to a digital form”. Here the information are organized into bits. Mostly these data will be converted into the form of image. But these can be edited by converting once again into necessary format and even back to image too. There are specific tools which the user needs to install for editing the digital documents.
The reason why we need digitization is that
a) We want to convert hard copy into soft copy and store it in system.
b) We would like to edit the data in the hard copy and preserve as a fresh copy.
Answer:
Explanation:
The study of the properties of solid materials and how those properties are determined by a material’s composition and structure is material science.
Answer:
// here is code in c++.
// include header
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables to read input
int userNum,x;
cout<<"enter the value of userNum and x :";
// read the input from user
cin>>userNum>>x;
// divide the userNum with x 4 times
for(int a=0;a<4;a++)
{
userNum=userNum/x;
cout<<userNum<<" ";
}
cout<<endl;
return 0;
}
Explanation:
Declare two variables "userNum" and "x". Read the value of these. Run a for loop 4 time and divide the "userNum" with "x" and print the value of "userNum".
<u>Output:</u>
enter the value of userNum and x :2000 2
1000 500 250 125
