A hacker is an individual who uses computer, networking or other skills to overcome a technical problem. The term hacker may refer to anyone with technical skills, but it often refers to a person who uses his or her abilities to gain unauthorized access to systems or networks in order to commit crimes.

Types of Hackers and What They Do: White, Black, and Grey

• 'Black Hat' Hackers. The term “black hat” originated from Western movies, where the bad guys wore black hats and the good guys wore white hats. ...
• 'White Hat' Hackers. ...
• 'Grey Hat' Hackers. ...
• Rootkits. ...
• Keyloggers. ...
• Vulnerability Scanner. ...
• SQL Injection Attack. ...
• Distributed Denial-of-Service (DDoS)

Price elasticity of supply = % change in quantity supplied / % change in price

Therefore, Price elasticity of supply= ((120-100)/(120+100))*( (5-4)/(5+4))

                                                           = 0.80

Since, price elasticity of supply is less than 1, supply of this commodity is inelastic. This means that a shift in price won't drastically affect the supply of the commodity.

Global politics, also known as world politics, names both the discipline that studies the political and economic patterns of the world and the field that is being studied. At the centre of that field are the different processes of political globalization in relation to questions of social power. Politics (from Greek: Πολιτικά, politiká, 'affairs of the cities') is the set of activities that are associated with making decisions in groups, or other forms of power relations between individuals, such as the distribution of resources or status. The academic study of politics is referred to as political science.

Identity theft, also known as identity fraud, is a crime in which an imposter obtains key pieces of personally identifiable information (PII), such as Social Security or driver's license numbers, to impersonate someone else

An antenna – usually 1/2 wavelength long – split at the exact center for connection to a feed line. Dipoles are the most common wire antenna. Length is equal to 1/2 of the wavelength for the frequency of operation. In an instructable, the formula for calculating antenna length was given as "length in meters =300 / frequency in MHz". The example given was for a Bluetooth antenna with a frequency of 2450MHz. The antenna length was calculated as 300/2450 = 0.1225m = 12cm.

The shadow zone is the area of the earth from angular distances of 104 to 140 degrees from a given earthquake that does not receive any direct P waves. The shadow zone results from S waves being stopped entirely by the liquid core and P waves being bent (refracted) by the liquid core. The earthquake waves develop shadow zones because: (i)The P and S waves follow a curved path in the interior of the earth which proves that the density increases inside the earth. (iii)On reaching the core 'S' waves disappear and P waves are refracted as a result there is no wave for a distance.

One of the main advantages of online file storage and sharing is that collaboration is smooth. You can share files instantly, access information quickly, and avoid any unnecessary delays. That's not all; you can work from anywhere and collaborate in real time with people in any part of the world. Shared Documents allow a department to collaborate on documents. It's also possible to track versions associated with a file so that it is possible to rollback to an earlier version of the document if necessary. It is also possible to set custom permissions for folders in shared documents.

All probability distributions can be classified as discrete probability distributions or as continuous probability distributions, depending on whether they define probabilities associated with discrete variables or continuous variables.

Discrete vs. Continuous Variables
If a variable can take on any value between two specified values, it is called a continuous variable; otherwise, it is called a discrete variable.

Some examples will clarify the difference between discrete and continuous variables.

Suppose the fire department mandates that all fire fighters must weigh between 150 and 250 pounds. The weight of a fire fighter would be an example of a continuous variable; since a fire fighter's weight could take on any value between 150 and 250 pounds.
Suppose we flip a coin and count the number of heads. The number of heads could be any integer value between 0 and plus infinity. However, it could not be any number between 0 and plus infinity. We could not, for example, get 2.5 heads. Therefore, the number of heads must be a discrete variable.

In accounting, there are two common uses of the term stock. One meaning of stock refers to the goods on hand which is to be sold to customers. In that situation, stock means inventory.

The term stock is also used to mean the ownership shares of a corporation. For example, an owner of a corporation will have a stock certificate which provides evidence of his or her ownership of a corporation's common stock or preferred stock. The owner of the corporation's common or preferred stock is known as a stockholder.

It's related to water cycle as the line says that "I give back life to my origin" . We understand from it that Rain is the important thing for every living being . And as so water evaporates from rivers etc . which then form clouds and then comes down again in the form of rain and as we say it a water cycle it happens cyclically every time . So the origin in this is from where water evaporates and it came back there only again.

Howard Carter, was a British archaeologist. He was the man who first discovered Tut’s tomb in 1922. He found three nested coffins of Tut.

Meditation : It is the seventh element of yoga and is also called Dhyana. It refers to concentration on specific objects, sounds or actions. This helps us to eliminate unwanted, undesirable and destructive thoughts so that a calm and healthy state of mind is achieved.

A constitution is a set of rules through which a country or state operates. Some countries have unwritten constitutions which means there is no formal constitution written in one particular document. Their constitutional rules are originated from a number of sources. Britain sources its constitution from a number of important statutes, or laws, as well as principles decided in legal cases and conventions. New Zealand and Israel are two other countries that do not have formal written constitutions. Other nations have formal written constitutions in which the structure of government is defined and the respective powers of the nation and the states are written in one single document. These systems may also include unwritten conventions and constitutional law which can inform how the constitution is interpreted. Australia, India and the United States are examples of countries with a written constitution.
