Global warming is a gradual increase in the Earth's temperature due to effect of greenhouse gases, such as carbon dioxide emission from burning fossil fuels and deforestation. These gases are suspended in our atmosphere and go on accumulating there. They trap the heat which would otherwise escape from earth.
There are two causes of global warming. Natural and man-made.
Natural cause, for example, is the release of methane gas from arctic tundra and marshes. Methane gas is a greenhouse gas and traps the heat from the sun. Another natural cause is the climate change which usually lasts about 40, 000 years.
Man-made causes include pollution by means of deforestation, burning of fossil fuels, use of manure in our agriculture, mining for coal and oil. Even increase in the population is responsible for global warming. Because, in all the above mentioned causes, we somehow or the other, release greenhouse gases. This leads to even more trapping of heat and thus global warming increases.
Earth's temperature has boosted 0.8 degree Celsius since 1880, much of this in the recent decades. And the rate is still on the rise. 20th century's last two decades were hottest in 400 years.
Although humans have survived things as famine, stretches of warmth and cold and more, but its a fact that entire societies have collapsed due to dramatic change in climate. Earth has started to show various signs and fingerprints of global warming such as rising seas, change in rainfall patterns, melting of icecaps, widespread vanishing of entire animal populations and bleaching of coral reefs. Massive ice sheets are shrinking and less ice leads to more warming and thus feeds the global warming.
This problem has been created by us. And we can also solve it if we have the willpower and stick-to-itiveness. Moving to renewable energy resources (wind, solar, geothermal, and bioenergy), using the energy more efficiently, by increasing the efficiency of our cars, by planting more trees and by creating new "free energy" sources such as wind power or electric cars. By following the above mentioned steps effectively, we can constrain and inhibit global warming.
In summary the best solution to stop global warming is to plant massive amounts of trees, and we need to drastically reduce emissions. There really is no other secret recipe to stop global warming and find a solution. Incredible new technologies are needed and we need to take better care of our environment.
Social media’s development has been incredible and exceptional. The growth is such that it seems that there is endless potential. A huge and amazing numbers in shape of untapped market is still present out there to be taken care of. You name it how many brands have made it big in the social media. Orkut, Hi 5, Facebook, MySpace, Google buzz are a few brands that have made it huge in the last decade and are still growing at the rate of knots. This has brought a kind of rivalry among players. Such rivalry has been running b/w Google and facebook
The launch of Google plus seems to be another of Google’s numerous attempts to take some share of facebook. The 1st step it took was to over take Orkut 1st and redesign it in such a manner that it over takes Orkut again. But facebook Orkut was doing really well. Facebook out ran Orkut extremely quickly. Google’s this attempt failed as it did not produce the required results and Google had to discontinue wasting on it. This was not it. They then introduced two of their own products with their own brand name attached to it. The introduction of the two products of Google namely “Google wave and Google Buzz” were in theory good products but it completely failed to capture the market and it did not present any challenge to facebook as the people within Google had anticipated.
The latest of Google’s desperate attempt to enter the social media is now with “Google plus”. This offers a complete unique video chatting experience named as hang out. No other social website has been able to provide such a value addition for the users. This is a really good addition. But will it be able to carter to the right kind of market and will it be to take away people from facebook that remains to be seen in the coming future.
Other option with Google plus are huddle, spark and circles. This has direct connection with what facebook is presenting. It is simple heads on war. It remains to be seen that at the end of the day who will come out as the winner. Facebook has a lead in terms that they are long way ahead with already captured market. Google plus has to do all the cutting of pie share or market share. One could say that this battle shall only be better for us users as more and more features that will be not only exciting but inducing shall be introduced to keep us attached to our profiles. Interesting times ahead for all of us I say.
Computer is an electronic device which works according to the set of instruction given to it. As a machine we will define computer, a computer is a machine that is used to carry the logical and arithmetic operations. Computer can be used for multi operations but work on single instruction in a single time. So we may say that computer is a programmable machine which works according to the set of instruction given to it. The computer has two types of memory permanent and non permanent memory. In other words we may say that volatile and non volatile memory.
These are known as random access memory (RAM) and the other one is read only memory (ROM). There is also a hard disk memory which is used to store the information and data on permanent basis. In these era of information technology, without computer is no life. In all case you are working in office or you are sitting in your library for learning purposes, you must need computer or the form of computer which is portable generally known as laptop.
The personal computers have generally four types of functions which are as follows:
• Control Unit
• Memory
• Arithmetic logical unit (ALU)
• The input and output devices
The control unit is also known with the name of control system. It plays a very vital role in managing all types of components of computer. So it is also called brain of computer because it has to control each and every component of the computer in order to solve the problem according to these of instructions given to it. The registers which are used to transfer or for travelling of data help to ménage the data and information in a proper way. There is also a program counter which is used to decode the data as well as for decoding the information. It is generally denoted by CU. The central processing unit is also a part of control unit and has a core importance in controlling all the components of the computer.
There are two types of memory in computer, one is volatile and other I non volatile. The random access memory is used to store the information for temporary basis and you can easily read or write or you can say you are allow to make changes in the memory while on the other hand read only memory is used to store the information for permanent basis and it can be write once at the time of manufacturing and you cannot allow to make change in it. One another important memory is cache memory.
The arithmetic logical unit is used to control the arithmetic operations because computer has to work in binary digits. The input and output devices are very much important to run the computer
It was said by Aristotle that friendship means “single soul having two bodies”.
The friendship is considered as soul relation between two individuals. There should be mutual understanding between the two individuals so that they can easily understand themselves. It is one of the unique relationships on the earth. Finding good friend is the great blessing of Allah Almighty for someone. We define friend as “friend in need is a friend indeed”. This relationship is not a materialistic in fact it is a relationship of hearts among the people. Heart is the most prominent and attractive part of the body familiar is the case with our friends in our life. An old saying is that “A man is known by the company he keeps” which means you are recognized by your friend. If they have good character you will also be considered a good human being and if your friends are notorious then you will be considered a bad personality in the society. It proves that friends play a great role in our life and has great impact on our personality.
There are lots of universal truth about friendship and friends. One of those is that if you have one friend it is sufficient, if you have two friends it is enough and if it is more than two it is not possible. This shows that this relationship can be found in one or two people and if the number exceeds they are all not categorized as friends which does not look a true and sound statement. We believe in having more friends in order to play a great role in our daily lives. There should be no restriction on number of friends because friends are like beautiful flowers and you know garden always look more beautiful as it have more flowers in it. And you know the fragrance of flowers is like everywhere in the world and flowers are the part and partial of each and every ceremony and celebrations in our lives.
At the same spot the friends stands. They have the same position in our lives as mentioned above flowers in the world. Without Friends there is no meaning of life, we cannot enjoy properly without our friends and even celebrations do not look charming and attractive in the absence of friends. Another important aspect of friendship is that we learn a lot in the relation of friendship. If we have good friends, we can learn a lot of good things from them such as good habits including speaking truth, avoiding bad meetings, avoiding lose talks and can also polish our character in the beautiful and charming light of friendship which leads us to become a role model for the society.
