Tablet Computers - IMPACT



Steve Jobs introduced the first Tablet Computer to the world as an iPad

and since then it has become a rage among people since its introduction in 2009 millions of iPads have sold in USA and across the world. The tablet computer is an easy to use keyboard less minicomputer with a touch screen and has a mini operating system with which one can surf the internet,take photographs,create documents,view pictures ,view and make videos and do all the basic computing. The screen sizes normally begin with 7 inch and go up to about 10.1 inch. The iPad though had a 10.1 inch screen and used the iOS operating system which also happens to be the operating system of Apple's iPhone. Introduction of iPad sprang up the Tablet revolution across countries iPad was expensive alright but various other companies around the world came out their own version of Tablet computers which used Google's open source Android as its operating system.
                
                       This tablets are much cheaper than a standard desktop or a

laptop and easier to carry around all of them are WiFi enabled for internet access also they have dongle support. There are tablets which can be used as a mobile phone with a sim and internet access is possible through 3G connection. These tablets are a boon to developing and low income countries where PC penetration is still low. They can be a great aid for education,being flat book like structure it can be used to store books in pdf forms or as ebooks. Thus a single SD card can store thousands of books thus one does not need lots of cupboards or space at home to set up a library all

one needs to do is to download a book from the internet and store it in an SD card or a pen drive. This book can have web links that can open on a single click one can embed Youtube videos in such books, at the same time saving lots of paper and saving lots of trees from being cut. Power management is a major issue of this tablet computers but with the increase in the processing power of the ARM processors which consume very very little power as compared to Intel and AMD processors they have become standard processors in all mobile devices and tablets however Intel with its Atom processors is also looking to enter the market.



                In the next few years Tablets are expected to replace the laptops the processing power of the low energy consuming ARM processors is bound to go up it would be interesting to see how INTEL and AMD respond to this challenge but one thing is for sure the Tablet computers by its light weight,low price with easy to use and cute features would go a long way in ending the digital divide the exits in the world.
