In olden days people used to refer the dictionary book or by asking the people, parents about an answers which u dont know.
then now in the future of encyclopedia, were to get some facts in the form of are big book which is sometimes very heavy to take it out of our selves because of laziness and not only that in formation get updates every months and u needed scrap the older books to buy the new books at the cost of thousands.
they came the wikipedia all is just need a internet connection and a computer and any thing what do you want just type there the name of the thing for which u need the details.
you can get any kind of famous places or cities and countries, places, events, movies, and actress names and their biography and list of awards they attain its more than a dictionary.
the another good thing with wikipedia is every product detail is embedded with hyperlinks. and by clicking on it you can get into the particular page and u can get the result and they are highlighted in bue colour and it makes easier further.
it takes less time to take any result beacause it is advanced and many more companies working on it refers to much prominence about their sites.
though I am using this wikipedia for any results among my self for over 10 years and I have very much satisfied among this website.
