What is REMOTE ACCESS TROJAN

What Is RAT Or Remote Access Trojan ?

RAT stands for Remote Access Trojan or Remote Administration Tool. It is one of the most dangerous virus out their over the internet. Hacker can use RAT to get complete control to your computer. He can do basically anything with your computer. Using RAT hacker can install keylogger and other malicious viruses remotely to your computer, infect files on your system and more. In this post i will tell you about what hacker can do with your computer using RAT and tell you about some commonly use RAT by hackers.

 What is RAT ?

As i have told you in my introduction paragraph RAT is Remote Access trojan. It is a peace of software or program which hacker uses to get complete control of your computer. It can be send to you in form of images, videos or any other files. Their are some RAT that even your antivirus software can not detect.  So always be sure about what you are downloading from the internet and never save or download files that anonymous user send you  over the mail or in chat room.

 What You Can do With RAT ?

Once a RAT is installed on any computer hacker can do almost anything with that computer. Some malicious task that you can do with RAT are listed below:

• Infecting Files
• Installing Keyloggers
• Controlling Computer
• Remotely start webcam, sounds, movies etc
• Using your PC to attack Website (DDOS)
• View Screen

 Harmless RAT or Good RAT

As you have seen how harmfull RAT are for your computer, but their are some good RAT which some of you might be using daily. You might have heard of TeamViewer, it is a software which you use to control some one's computer with his permission for file transfer, sharing your screen and more.

 Some Commonly Used RAT

• ProRAT
• CyberGate RAT
• DarkComet RAT

C PROGRAM FOR CALCULATING POWERS

SOURCE CODE: 

/*                  Name : Power Function

                        Created by    : Tejprakash Sharma

                       Created on    : 26th September 2016

                    Applications or Usage : It can calculate integer powers of any number

                     Limits  : It can not calculate accurately a number more than 2^56 or                                                              72,05,75,94,03,79,27,926

*/

#include <stdio.h>

#include <conio.h>

int main()

{

    double power;

    int a,count;

    float max,num;

    char choice;

    printf("\n Which number's power you do want to calculate: ");

    scanf("%f",&num);

    printf("\n \n How many as you want to know the power of %2.2f: ",num);

    scanf("%d",&max);

    power = 0;

    for(count=1 ; count <= max ; count++)

        {

            a = 0;

            while(a <= count)

            {

                if(a == 0)

                    power = 1;

                else

                    power *= num;

                a++;

            }

        printf("\n %3.2lf^%d  = %lf",num,(count),power);

        }

    printf("\n \n Do you want to start it again- \n \n If you do then press 'S'");

    scanf(" %c",&choice);

    if (choice == 'S' || choice == 's')

        main();

    return 0;

}

Short DESCRIPTION:

                                    This program is made for calculating powers of any number. Here in this program we used variable- 

1.) "power" to store powers,

2.) "num" for storing the number whose power we wanted to calculate,

3.) "max" for storing highest power term,

4.) "a" & "count" as temperory  variable,

5.) "choice" for storing the choice what the user wants to do.

DAILY LIFE USES OF DIFFERENTIATION AND INTEGRATION

DAILY LIFE USES OF DIFFERENTIATION AND INTEGRATION

NEED of CALCULAS:  

                                      In Isaac Newton's day, one of the biggest problems was poor navigation at sea. Before calculus was developed, the stars were vital for navigation. Shipwrecks occurred because the ship was not where the captain thought it should be. There was not a good enough understanding of how the Earth, stars and planets moved with respect to each other.

                          Calculus (differentiation and integration) was developed to improve this understanding.

                         Differentiation and integration can help us solve many types of real-world problems.  We use the derivative to determine the maximum and minimum values of particular functions (e.g. cost, strength, amount of material used in a building, profit, loss, etc.).

                        Derivatives are met in many engineering and science problems, especially when modeling the behavior of moving objects.

SOME GENERAL APPLICATIONS : 

1.) It is used ECONOMIC a lot, calculus is also a base of economics.

2.) it is used in history, for predicting the life of a stone.

3.) it is used in geography, which is used to study the gases present in the atmosphere.

4.) It is mainly used in daily by pilots to measure the pressure n the air.

Appllications of INTEGRATION :

1.) Applications of the Indefinite Integral shows how to find displacement (from velocity) and velocity (from acceleration) using the indefinite integral. 

2.) Area under a Curve and Area in between the two curves. 

3.) Volume of Solid of Revolution explains how to use integration to find the volume of an object with curved sides, e.g. wine barrels.

4.) Centroid of an Area means the centre of mass. We see how to use integration to find the centroid of an area with curved sides.

5.) Moments of Inertia explain how to find the resistance of a rotating body. We use integration when the shape has curved sides.

6.) Work by a Variable Force shows how to find the work done on an object when the force is not constant. 

7.) Electric Charges have a force between them that varies depending on the amount of charge and the distance between the charges. We use integration to calculate the work done when charges are separated.

8.) Average Value of a curve can be calculated using integration.

There are also some electronics applications.
