iPad 2

Apple unveiled the iPad 2, the second generation of the device, at a March 2, 2011, press conference. About 33% thinner than its predecessor, the iPad 2 has a better processor, a dual core Apple A5 that Apple says is twice as fast as its predecessor for CPU operations and up to nine times as fast for GPU operations. It retains the original's 10-hour battery life and has a similar pricing scheme. While prices were kept the same in the United States, the iPad 2 sold for less in other countries such as the United Kingdom.

The iPad's touchscreen display is a 9.7 in (25 cm) liquid crystal display (1024 × 768 pixels) with fingerprint-resistant and scratch-resistant glass. Steve Jobs backed the choice of screen size, saying a 7-inch screen would be "too small to express the software." He said 10 inches was the minimum for a tablet screen. Like the iPhone, the iPad is designed to be controlled by bare fingers; normal gloves and styli that prevent electrical conductivity may not be used, although there are special gloves and capacitive styli designed for this use.

The iPad can use Wi-Fi network trilateration from Skyhook Wireless to provide location information to applications such as Google Maps. The 3G model contains A-GPS to allow its position to be calculated with GPS or relative to nearby cellphone towers; it also has a black plastic accent on the back side to improve 3G radio sensitivity.

For wired connectivity, the iPad has only a TRRS headphone jack and a proprietary Apple dock connector; it lacks the Ethernet and USB ports of larger computers.

the iPad has two internal mono speakers located on the bottom-right of the unit. In the original iPad, the speakers push sound through two small sealed channels leading to the three audio ports carved into the device, while the iPad 2 has its speakers behind a single grill.

Dual-core A5 chip
Two powerful cores in one A5 chip mean iPad can do twice the work at once. You’ll notice the difference when you’re surfing the web, watching movies, making FaceTime video calls, gaming, and going from app to app to app. Multitasking is smoother, apps load faster, and everything just works better.

Superfast graphics
With up to nine times the graphics performance, gameplay on iPad is even smoother and more realistic. And faster graphics help apps perform better — especially those with video. You’ll see it when you’re scrolling through your photo library, editing video with iMovie, and viewing animations in Keynote.

Long Battery life
Even with the new thinner and lighter design, iPad has the same amazing 10-hour battery life.1 That’s enough juice for one flight across the ocean, or one movie-watching all-nighter, or a week’s commute across town. The power-efficient A5 chip and iOS keep battery life from fading away, so you can get carried away.

Two cameras
You’ll see two cameras on iPad — one on the front and one on the back. They may be tiny, but they’re a big deal. They’re designed for FaceTime video calling, and they work together so you can talk to your favorite people and see them smile and laugh back at you.

Multi-Touch
Technology is at its best when it feels completely natural, almost like there’s no technology at all. That’s Multi-Touch on iPad. You use your fingers to do everything, so everything you do — surfing the web, typing email, reading books, and swiping through photos — is easier and a lot more fun. How does it work? When your fingers touch the display, it senses them using electrical fields. Then it instantly transforms your taps, swipes, pinches, and flicks into lifelike actions. Just like that.

iOS 4, the world’s most advanced mobile operating system
iOS 4 is the operating system for iPad (along with iPhone and iPod touch). It lets you browse, read, and see everything just by touching the screen. It includes all the powerful, innovative, and fun built-in apps you use every day, many times a day. And it’s the platform on which more than 65,000 other amazing apps have been created for iPad. It’s highly secure, stable, and responsive, and it’s made to work seamlessly with the iPad hardware. iOS 4 is the reason no other device has yet come close to iPad.
