Simply an Operating System (OS) created by Google to run on any small electronic devices such as cellphones, e-books, Media Internet Devices (MID), netbooks, Internet tablets, and many others devices in the future. An OS is similar to Windows that controls your desktop or laptop personal computers. Google fully developed Android and make it into an Open Source. Now, any phone manufacturer can use Android without expensive license fee from Google. Because it is Open, manufacturer can modify Android without restriction, allowing it to fit the device they are making - total freedom. This makes it a big incentive for any device manufacturers to adopt Android. The ability to run tens of thousands of apps is another big incentive.To develop such apps, U must have knowledge, which comes after becoming Android Certified Programmer ( ACP).
There are many reasons why Googles Android phones are better than iPhone or any other Smartphones on the planet.
One main reason can be simplify in just one word: CHOICES !
Imagine a phone that is as capable and better than the iPhone but without the monopoly of one company, Apple. That is what Android is all about. The ability to run tens of thousands of apps just like the iPhone but with choice of phone models that you can choose from. The choice of with or without physical keyboard, shape, color, phone size, screen size, manufacturer, features, and phone carrier. No more monopoly by one company on one carrier. Choices drive competition. The competition within Android phone manufacturers itself will inevitably make Android phones even better than what it is today, and in a short period of time.
