A <u>schema </u>describes the structure, content, and access controls of a physical data store or database.

<h3>What is the kind of database that stores data in a different physical location?</h3>

Distributed databases are that are distributed across several physical locations. In distributed databases, the data are placed where they are used most often, but the whole database is available to each licensed user.

<h3>What is the structure of database management system?</h3>

The database system is separated into three components: Query Processor, Storage Manager, and Disk Storage.

Answer: Passive

Explanation: Passive scanning is the process that scans the possibility of the risk that can arise while data is received starting port to the destination. It does the scanning between the server and the client software to define vulnerability .

It cannot work in those network which don't persist the traffic.No false data that is present in the application is detected by it if the data is unclear.

Write a program that prompts the user to enter the center and a point on the circle. The program should then output the circle’s

sergij07 [2.7K]

Here is the code in C++.

#include <bits/stdc++.h>

using namespace std;

// function to calculate distance between two points

double distance(int a,int b,int c,int d )

{

// return the distance between center and point

return sqrt(pow(c - a, 2) +

pow(d - b, 2) * 1.0);

}

// driver function

int main()

{

// variables to store coordinates

int x1,y1,x2,y2;

cout<<"Please Enter the center(x y) of the circle: ";

//reading center

cin>>x1>>y1;

cout<<"\nPlease Enter a point(x1 y1) on the circle:";

//reading point

cin>>x2>>y2;

// calling distance() function with 4 parameters

double rad=distance(x1,y1,x2,y2);

// calculating Radius and print

cout<<"Radius of circle is: "<<rad<<endl;

// calculating Diameter and print

cout<<"Diameter of circle is: "<<2*rad<<endl;

// calculating Circumference and print

cout<<"Circumference of circle is: "<<2*3.14*rad<<endl;

// calculating Area and print

cout<<"Area of circle is: "<<3.14*rad*rad<<endl;

return 0;

}

Explanation:

First it will read coordinates of center and point on the circle.The distancebetween center and point on circle is Radius. Call distance() function withfour parameters which are coordinates of center and point. This will return the value of Radius. Diameter is 2 times of Radius.Diameter of a circle is 2*3.14*Radius. and Area of the circle is calculate as 3.14*Radius*Radius. After finding these value print them.

Output:

Please Enter the center(x y) of the circle: 0 0

Please Enter a point(x1 y1) on the circle: 3 4

Radius of circle is: 5

Diameter of circle is: 10

Circumference of circle is: 31.4

Area of circle is: 78.5
