new iPad


Resolutionary

Introducing the new iPad. With the stunning Retina display. 5MP iSight camera. And ultra-fast wireless.

Starting from Rs.30,500.

Retina display. See everything like never before.

Four times more pixels than iPad 2. Razor-sharp text. Richer colours. The Retina display transforms the entire iPad experience. So everything looks and feels incredibly lifelike and perfectly detailed.

The best display ever on a mobile device.

Everything you do with iPad, you do through its large, beautiful display. And when the display is better, the entire iPad experience is better. The Retina display on the new iPad features a 2048x1536 resolution, 44 per cent greater colour saturation and an astounding 3.1 million pixels — in the same 9.7-inch space. That’s four times the number of pixels in iPad 2 and a million more than an HDTV. Those pixels are so close together, your eyes can’t discern individual ones at a normal viewing distance. When you can’t see the pixels, you see the whole picture. Or article. Or game. In ways you never could before.
The new iPad has a million more pixels than an HDTV.

Pixel-perfect performance.

The A5X chip with quad-core graphics drives four times the pixels of iPad 2, yet it delivers the same smoothness and fluidity iPad is known for. Even with all that extra oomph, the new iPad still gets an amazing 10 hours of battery life.

More power on display.

The Retina display on the new iPad wouldn’t be possible without the new and powerful A5X chip. It drives power to every one of the 3.1 million pixels in the display. And its quad-core graphics processing makes everything you do on iPad feel incredibly responsive. From the little things like swiping, scrolling and pinching to the big things like editing photos in the new iPhoto, applying titles and transitions in iMovie and, of course, playing games.

Instant on. Touch and go.

You use your iPad all the time. A few minutes here, an hour or so there. And each time you press the Home button or open the Smart Cover, it’s ready to go. Instantly. That’s the work of flash storage. It’s fast and reliable, so you can get to your apps and do whatever you need to do, pronto.

Battery life spared.

The new iPad features a Retina display with four times the pixels of iPad 2 and quad-core graphics. How much of an effect does that have on battery life? Almost none. You still get up to 10 hours of power to read, watch, play, write and create whatever you want, all you want.1

The iSight camera. Your memories have never been clearer.

The new iPad features Apple’s 5-megapixel iSight camera. Designed with advanced optics, it lets you shoot gorgeous photos and 1080p HD video.

iSight Camera

Shoot 5-megapixel still images.

The 5-megapixel iSight camera features a backside illumination sensor that captures great-looking pictures whether by sunlight or candlelight. Autofocus, tap to focus and tap to set exposure functions mean every photo you take instantly becomes a frame-worthy gem. And with built-in face detection that automatically balances focus and exposure across up to 10 faces, there’s more room for more grins. So everyone look at iPad and say “Cheese”.

HD Video Recording

Record HD video in full 1080p.

Sometimes life takes you by surprise. You’re reading a best-seller on your iPad waiting for the morning train when you spy a gifted performer on the platform. Or you’re browsing the web on the sofa when your dog trots by wearing your daughter’s tutu. The iSight camera on the new iPad lets you capture all these unpredictable, beautiful and hilarious moments. In 1080p HD, no less. And with automatic video stabilisation, your recording is free of bumps and shakes. Which is a big advantage when you’re laughing uncontrollably.

It’s all in the lenses.

Megapixels matter. But the quality of a photo is determined by other things too — like the camera’s optics, image signal processor and software. The iSight camera uses advanced optics to give you the best picture possible. With an Æ’/2.4 aperture and a five-element lens, it captures light efficiently to produce a sharper overall image. And the hybrid infrared filter — typically reserved for expensive SLR cameras — keeps out harmful IR light for more accurate, uniform colours.

The larger Æ’/2.4 aperture lets in more light, so photos look brighter and better.

Ultra-fast wireless. Full speed ahead.

Built with the latest in wireless technology, the new iPad lets you connect to fast data networks around the world.2

World ready. And very well connected.

You use your iPad a lot. So it makes sense to want it with you wherever you go. The new iPad offers the most comprehensive support for fast networks around the world. It’s designed with mobile antennas that access a larger frequency spectrum. That means you can get online almost anywhere you are. You can even pop in a local SIM card to get a connection when you’re travelling.

Really really fast is your only option.

The new iPad supports fast mobile data networks around the world, including HSPA, HSPA+ and DC-HSDPA.2 So you can browse the web, stream content or download a film at incredibly fast speeds: up to 21.1 Mbps with HSPA+ and up to 42 Mbps with DC-HSDPA.3

iPad as a personal hotspot.

Now for the first time, you can share the high-speed data connection on your iPad. If your carrier supports it, iPad can act as a personal hotspot for connecting up to five devices — such as a MacBook Air, an iPod touch or another iPad — over Wi-Fi, Bluetooth or USB.

iOS.

The world’s most advanced mobile operating system.

iOS is the magic behind iPad. It lets you see and do everything using Multi-Touch. It includes all the powerful, innovative and fun built-in apps you use every day, many times a day. It’s the preferred choice for app developers. And it’s yet another reason no other device comes close to iPad. Learn more about iOS

iCloud.

Your content.
On all your devices.

iCloud stores your music, photos, apps, mail, contacts, calendars, documents and more, and wirelessly pushes them to all your devices.4 So if you buy a song, take a photo or edit a calendar event on your iPad, iCloud makes sure it appears on your Mac, iPhone and iPod touch too. You don’t have to do a thing.Learn more about iCloud

App Store. Something for everyone. And everything.

Apps for iPad aren’t like anything else. That’s because every app — 200,000 and counting — is designed to work with iPad features like the beautiful 9.7-inch screen, Multi-Touch, the accelerometer, the gyroscope and more.

Over 200,000 apps to choose from.

The App Store is home to over 200,000 apps and counting — all made just for iPad. And many of them are free. You buy apps from the App Store using the same Apple ID you use to buy music from iTunes. Find an app you like, tap to buy it and it starts downloading instantly. iPad lets you know when updates are available, so your apps are always current.

Apps made just for iPad.

An app that’s made for iPad is genuinely made for iPad. That means it’s specifically designed to take advantage of the way iPad works. Need proof? Check out Apple’s beautiful iPhoto app on the new iPad. It’s just one of thousands of apps that let you do things with iPad you never thought possible. With iPhoto in the picture, the iLife family of apps for iPad — including GarageBand andiMovie — is complete.5

iPad Smart Cover. Designed for iPad. And vice versa.

More than a way to protect iPad from dust and scratches, the iPad Smart Cover can wake and sleep iPad with a simple open and close. It even folds back and instantly turns into a handy little stand.

A cover with magnetic appeal.

What a smart pair. iPad and the iPad Smart Cover, that is.6 Smart magnetic technology built into each one really pulls them together. The iPad Smart Cover snaps perfectly into place to protect your iPad screen. Open the Smart Cover and your iPad wakes up. Close it and your iPad goes to sleep. Fold the Smart Cover and it becomes a stand. It’s all just so, well, smart.

3-Dimensional Computer Processor

 

Scientist at University of Rochesterb have developed a new generation of Computer Processors. These processors are based on 3-Dimensional Circuits in contrary to 2-Dimensional Circuits of today.

This can be said as the next major advance in computer processors technology. The latest 3-D processor is running at 1.4 gigahertz in the labs of University.

PAST ATTEMPTS VS LATEST RESEARCH

In the past attempts of making 3-D chips, scientist were just making a stack of regular processors. But at University of Rochesterb it was designed and built specifically to optimize all key processing functions vertically, through multiple layers of processors, the same way ordinary chips optimize functions horizontally.

This design means that every tasks such as Synchronicity, Power Distribution, and Long-Distance Signaling are all fully functioning in three dimensions for the first time.

EBY FRIEDMAN: THE MAN BEHIND 3-D CHIPS

Eby Friedman and his students has designed this chip, which uses many of the tricks of regular processors, but also accounts for different impedances that might occur from chip to chip, different operating speeds, and different power requirements. According to Eby Friedman, Professor of Electrical and Computer Engineering at Rochester and faculty director of the pro of the processor says:- "I call it a cube now, because it's not just a chip anymore. This is the way computing is going to have to be done in the future. When the chips are flush against each other, they can do things you could never do with a regular 2D chip"


3-D Chip

TODAYS INTEGRATED CHIPS AND PROBLEMS

The problem with today's technology of integrated circuits is that, beyond a limit it is impossible to pack more chips next to each other which limits the capabilities of future processors. So number of integrated circuit designers anticipate someday expanding into the third dimension, stacking transistors on top of each other.

IMPORTANCE

Vertical Expansion of chips has lots of technical difficulties and the only solution to this is to design a 3-D chip where all the layers interact like a single system. According to Friedman: Getting all three levels of the 3-D chip to act in harmony is like trying to devise a traffic control system for the entire United States-and then layering two more United States above the first and somehow getting every bit of traffic from any point on any level to its destination on any other level-while simultaneously coordinating the traffic of millions of other drivers.
Now if we replace the two United States layers to something more complicated like China and India where the driving laws and roads are quite different, and the complexity and challenge of designing a single control system to work in any chip begins to become apparent.

The 3-D Chip is essentially an entire circuit board folded up into a tiny package. With this technology the chips inside something like an iPod could be compacted to a tenth their current size with ten times the speed.

4G Technology

 

Fourth Generation (4G) mobiles

4G also called as Fourth-Generation Communications System, is a term used to describe the next step in wireless communications. A 4G system can provide a comprehensive IP solution where voice, data and streamed multimedia can be provided to users on an "Anytime, Anywhere" basis. The data transfer rates are also much higher than previous generations.

The main objectives of 4G are:

1)4G will be a fully IP-based integrated system.

2)This will be capable of providing 100 Mbit/s and 1 Gbit/s speeds both indoors and outdoors.

3)It can provide premium quality and high security.

4)4G offer all types of services at an affordable cost.

4G is developed to provide high quality of service (QoS) and rate requirements set by forthcoming applications such as wireless broadband access, Multimedia Messaging, Video Chat, Mobile TV, High definition TV content, DVB, minimal service like voice and data, and other streaming services.

4G technology allow high-quality smooth video transmission. It will enable fast downloading of full-length songs or music pieces in real time.

The business and popularity of 4Gmobiles is predicted to be very vast. On an average, by 2009, this 4Gmobile market will be over $400B and it will dominate the wireless communications, and its converged system will replace most conventional wireless infrastructure.

Data Rates For 4G:

The downloading speed for mobile Internet connections is from 9.6 kbit/s for 2G cellular at present. However, in actual use the data rates are usually slower, especially in crowded areas, or when there is congestion in network.

4G mobile data transmission rates are planned to be up to 20 megabits per second which means that it will be about 10-20 times faster than standard ASDL services.

In terms of connection seeds, 4G will be about 200 times faster than present 2G mobile data rates, and about 10 times faster than 3G broadband mobile. 3G data rates are currently 2Mbit/sec, which is very fast compared to 2G's 9.6Kbit/sec.
