Answer: A. passive attacks
Explanation:
Passive attack is a type of attack where by a system is tracked and scanned to determine how vulnerable it is and to also detect open port. The major purpose of a passive attack on a network is to gain access to the information of the target without altering the data.
A passive attack on a network may not be necessarily malicious, it is a type of network attack that is very difficult to detect.
Methods of carrying out passive attacks.
•War driving: scanning of networks is carried out to detect Wi-Fi that are vulnerable.
•Dumpster driving: Attackers or intruders search for information from discarded computers and
other gadgets, those information can help to attack a network.
Answer:
False
Explanation:
The private member of a class is not accessible by using the Dot notation ,however the private member are those which are not accessible inside the class they are accessible outside the class .The public member are accessible inside the class so they are accessible by using the dot operator .
<u>Following are the example is given below in C++ Language </u>
#include<iostream> // header file
using namespace std;
class Rectangle
{
private:
double r; // private member
public:
double area()
{ return 3.14*r*r;
}
};
int main()
{
Rectangle r1;// creating the object
r1.r = 3.5;
double t= r1.area(); // calling
cout<<" Area is:"<<t;
return 0;
}
Output:
compile time error is generated
<u>The correct program to access the private member of class is given below </u>
#include<iostream> // header file
using namespace std;
class Rectangle
{
private:
double r; // private member
public:
double area()
{
r1=r;
double t2=3.14*r2*r2;
return(t2); // return the value
}
};
int main()
{
Rectangle r1;// creating the object
r1.r = 1.5;
double t= r1.area(); // calling
cout<<" Area is:"<<t;
return 0;
}
Therefore the given statement is False
Answer:
You need to do just as follows. First, you are required to click with the help of the mouse on the command that you can find in the Ribbon. Now list the three types you can proceed with the insertion point. You can firstly move the I-beam pointer through the mouse, by pressing over the home, end or arrow keys. And that is it you are done.
Explanation:
You also need to understand what are Ribbon commands.The Ribbon is the command menu interface of Excel. And it adds up together at one place the most commonly applicable actions in a visual and intuitive manner. And these actions form the main parts of the Ribbon. And the tabs are collectibles of the same types of groups of actions or commands. The commands permit to do certain actions or open any menu that points to further actions.
Answer:
The importance of generalization are as follow:
- The generalization bounds are basically used in various ranking algorithm for supporting various vector machine and it is very helpful in the system.
- The generalization bounds are helpful for minimize and reducing the empirical convex risk in the system.
- It is also important for handling and controlling the complex hypothetical spaces also handle various types of VC dimensions complexity.
- The generalization bounds are basically free from all the distribution bounds so that is why it is used in many probability measures.
