  The Internet , one of the modern scientific discoveries , has changed the mode of human life . It is widely used for various purposes . It can simply be defined as a means of connecting a computer to any other computers anywhere in the world via dedicated routers and servers . When two computers are connected over the Internet , they ca n send and receive all kinds of information .          The Internet has provided us with multiple advantages . For instance, it is a huge source of information because we can easily find information above anything we want to know on the Internet . There are numerous websites . Among such websites, Google is widely used by most of the Internet users . Because the Internet can be used as a store of knowledge , it can be used  in teaching- learning program as well . Nowadays, we can find any e-books and journals which have made it economical for the readers to read directly the e-materials rather than the printed ones . Thus, the Internet  has proved to

            G lobal W arming can be known as the increase in the average temperature of the earth's atmosphere due to different causes . According to scientists , its temperature is gradually increasing mainly because of human activities . Now this essay presents some of its causes , effects , and preventive measures and solutions .             Some of the major causes of global warming include ejection of unwanted gases or greenhouse gases due to human activities and volcanic eruptions . It has been estimated that average global surface temperature is likely to rise a further 1.1 to 6.4℃ during the 21st century as the result  of ejaculation of the gases . On Earth , the major greenhouse gases involve water vapor , carbon dioxide ( CO2 ) , ozone ( O 3 ) and nitrous oxide ( N 2O) . These gases are produced by burning solid wastes , fossil fuels , firewood and modern farming . Similarly , automobiles and factories are other factors that produce these produce these unwanted gases . Th

Cryptocurrency For Beginners Imagine you're having conversation with your friends now at same point in this conversation someone's going to bring up crypto currencies now crypto currencies is something that everyone  wants to talk about no one really knows how they work so today I'm going to fix that . Crypto currency explained since man ,  world currency has been a very important part of our lives in caveman era they use the barter system now the barter system involves goods and services being exchange among each other so now we have a situation where two person is exchanging five apples and getting oranges in return now barter system fell out of use because it had some glaring flaws now these flaws include having peoples requirement coincide for example say you have five apples and your friend has five oranges now until and unless your friend has a requirement of apple you can't get oranges .               You will not be ready to make an exchange for it there's i

                Information technology has brought an unmatchable revolution in the field of information and communication ; 'Facebook' as its new innovation has appeared as a social network service and website launched in February , 2004 . Nowadays , many people are used to using Facebook and its has become their culture . It has both pros and cons .             Facebook users create profiles with photos , lists of personal interests , contact information , and other personal information ,too . They can communicate with their friends ,both real & virtual , through private or public messages . One of the most popular applications of the Facebook is the photos application where users can upload an unlimited number of photos . Privacy system can be set for individual albums by limiting users . Similarly, another feature of the photos application is the ability to 'tag' users in a photos .        Facebook definitely provides users with multiple advantages . For example

The Early Earth    The early Earth was like a blurred patch of scalding rock and chocking fumes . But the space , in which it was floating , was  cold so the surface of the EARTH also began to cold , So the surface of the Earth also began to cool down . Approximately 3,000 million years ago , the Earth was cool enough for land masses to form . Even so , our planet remained an alien world for the next several hundred million years . Rafts of solid rock drifted in the magma like dark ice floes .   Atmosphere ,Weather and Oceans -) Gases , carbon dioxide , nitrogen , gusted out from the cooling rock and enveloped the planet in a blistering atmosphere devoid of oxygen . As the Earth cooled, the steam began to condense into water , and the water ran down wherever the rocks were lower , which perhaps made the first oceans . These first oceans may have been short-lived . Space rubble  left over from the birth of the planets bombarded Earth continuously .     The greatest impact might have boi

  Physics Note ( Force ) 1) Clarify the statement , ''acceleration due to gravity of the earth is 9.8m/s^2 '' ? 👉 Acceleration due to gravity of earth is 9.8m/s^2 means that every freely falling object towards the earth  increase its velocity by 9.8m/s in every second i.e., at the rate of 9.8m/s per second . 2)The moon has no atmosphere , why ? 👉 Moon has no atmosphere because it has very small gravity so that it cannot hold the gases and therefore the gases escape into the space (with their escape velocity) . 3)Why is the weight of a body more at the pole than at the equator of the earth ? 👉 We know that the weight of a body (W) = m*g . For the the constant mass (m) of a body , the weight is directly proportional to acceleration due to gravity i.e., W α g. Since the value of "g" is more at the pole of the earth due to having smaller radius than  that of the equator , so, the weight of object is more at poles than at the equator of the earth . 4)A piece of
