acually they have a lot of jobs
1) the keep dangerous websites download viruses on your device
2) it finds the most accurate websites that have the most accurate information based on what you searched
3)it saves all your passwords so you dont forget it (which obviosly your google is bad at)
4)See your search history – Yep. Everything that you have ever searched for in the past, can be brought up again provided you have a Google account (on Google Play Store, Gmail, Google+ or any other Google service). Simply visit http://google.com/history to see all your past searches
5)Get definitions – Use the keyword “Define” before any word entered in the Google search bar, and it will throw up the dictionary meaning of the entered text. Highly useful when looking for a scientific definition or checking the validity of a word while playing Scrabble!
6)Set up a price range – When looking up Google for items in a certain price range, simply put two dots between the two prices. E.g. while looking for a laptop in the price range of $500 to $1,000, enter the following text “Laptop $500..$1,000”. It won’t show laptops under and above the mentioned prices.
7)Setting up Google as your alarm – Told you Google is more than just a behemoth search engine. You can use the Google search bar as a timer or an alarm clock, merely by entering the text “set a timer” in the box. Once you press Search, the Google search automatically sets up an online timer for you, and lets you know when the time is up!
8)Comparing items – You can use the Google search box to compare two different items. Put in a “v/s” between two items or products you want to compare, and Google will throw up a pretty nifty comparison chat for you. Also handy when you want to compare the composition or nutritional value of two food products.
9)“Tilt” – One of those wacky fun ideas of Google. Simply type Tilt in the search bar, and Google will “tilt” the screen for you. Cool!
