How TECHNOLOGY has CHANGED our LIVES...

what is Android (OS) ?

Android is a mobile operating system (OS) based on the Linux kernel and currently developed by Google. With a user interface based on direct manipulation, Android is designed primarily for touchscreen mobile devices such as smartphones and tablet computers, with specialized user interfaces for televisions (Android TV), cars (Android Auto), and wrist watches (Android Wear).

The OS uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard. Despite being primarily designed for touchscreen input, it also has been used in game consoles, digital cameras, and other electronics.

Internet - what NEXT ?

The Internet is just a few decades old, but in that short span of time it has experienced significant changes. It grew out of a hodgepodge of independent networks into a global entity. It serves as a platform for business, communication, entertainment and education and you can connect to this enormous network through dozens of different devices.

What's next? When you can call up minute trivia about the most obscure subject you can think of with a couple of taps on a smartphone screen, where else can you go? The answer isn't entirely clear, but the possibilities are exciting.

One thing that seems certain is that "data transmission speeds will increase globally". According to Akamai Technologies, which publishes a quarterly state of the Internet report, the average global data transmission speed in late 2009 was 1.7 megabits per second. Compare that to the record for data transmission speed set by Bell Labs: 100 petabits per second. This is equivalent to 100 billion megabits per second. At that speed, "you could transmit 400 DVDs worth of data every second".

That's an enormous gap between what's currently possible and what's commercially available. But as time passes, the costs of producing ultra-high-speed networks will decrease. Eventually, the average consumer will be able to download a high-definition movie in a second or play cloud-based video games without a hint of lag.
