									iPad 2
The iPad 2 is the second generation of the iPad, a tablet computer designed, developed and
marketed by Apple. It serves primarily as a platform for audio-visual media including books,
periodicals, movies, music, games and web content, and is available in black or white. The
Foxconn China-manufactured iPad 2 has a lithium-ion polymer battery that lasts up to 10 hours,
a new dual core Apple A5 processor and VGA front-facing and 720p rear-facing cameras
designed for FaceTime video calling.

Apple unveiled the device on March 2, 2011, began selling it by website and retail stores on
March 11, and released it in 25 other countries on March 25, including Australia, Britain and
Canada. Apple announced that the iPad 2 would be released in Hong Kong, South Korea,
Singapore and other countries on April 29, 2011.

Apple sent invitations to journalists on February 23, 2011 for a media event on March 2.

Apple CEO Steve Jobs revealed the device at the Yerba Buena Center for the Arts on March 2,
2011, despite being on medical leave.

Apple began selling the iPad 2 on its website on March 11and in its U.S. retail stores at 5 pm
local time on that date. Many stores in major cities, such as New York, sold out within
hours.Online shipping delays had increased to three to four weeks on Sunday and four to five
weeks by Tuesday. One analyst predicted that Apple would sell 35 million iPad 2s in 2011.

The iPad 2 was released internationally in 25 other countries on March 25, 2011. The countries
included Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France,
Germany, Greece, Iceland, Italy, Ireland, Hungary, Luxembourg, Mexico, Netherlands, New
Zealand, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Apple
announced that the iPad 2 will be released in Hong Kong, Japan, South Korea, Singapore,
Malaysia and other countries in April 2011.

The March 25 release date for Japan was postponed due to the earthquake and tsunami which
struck the entire nation on March 11, 2011. The iPads may be delayed due to the NAND flash
storage chip used in the iPads being created by Toshiba, which has been affected by the
earthquake and tsunami and has closed indefinitely. The slowdown caused analysts to
downgrade Apple's stock.

Software

The iPad 2 uses iOS 4.3.5, released on July 25, 2011 which fixed a security vulnerability with
certificate validation.

iOS 5 is scheduled to be released on October 12, 2011 and is slated to bring over 200 new user
features including Notification Center, iMessage, and an updated notifications system, using a
new "banner" style instead of the originally used "alert" style.
Hardware


The iPad 2 includes a new A5 processor, front and rear cameras plus a 3 axis gyroscope. Several
components were made smaller to fit the new iPad.

Screen and input

Both original iPad and iPad 2 have four physical switches, including a home button near the
display that returns the user to the main menu, and three plastic physical switches on the sides:
wake/sleep, volume up/down, and a third switch for either screen rotation lock or mute. The
home button on the iPad 2 is "easier to double tap" than the previous generation of the iPad.

Apple reduced the size of the iPad by eliminating the stamped sheet metal frame from the
display, integrating new thinner glass technology for the touch screen overlay, and slightly
reducing the space between the display and battery. The iPad 2's screen is thinner, lighter, and
yet stronger than the original iPad's. The iPad 2 also supports screen mirroring via the digital AV
adapter.

Airplay

Airplay is a feature built in to iOS. It allows the iPad to stream videos, photos or audio from any
Airplay enabled app to Apple TV, an Airport Express unit or to some third party speakers. Some
built in apps such as Photos, Videos and iPod are AirPlay compatible.

Power

The iPad has a 25 w·h rechargeable lithium-ion polymer battery[1] that lasts 10 hours, like the
original iPad. It is charged via USB or included 10 W, 2 A power adapter. The battery is 2.5 mm
thick, 59% smaller than the original and has three cells instead of two. The improvements
allowed the injection-molded plastic support frame to be omitted. The 10 W USB power adapter
provides 4x the power of a conventional USB port.

Cameras

The revised tablet adds front- and rear-facing cameras, which allow FaceTime video calls with
the iPhone 4, fourth-generation iPod Touch and Macintosh computers (running Mac OS X 10.6.6
or later with a webcam). The 0.3 MP front camera shoots VGA-quality 30 frame/s video and
VGA-quality still photos.The 0.7 MP back camera can shoot 720p HD video at 30 frame/s and
has a 5x digital zoom. Both shoot photo in a 4:3 fullscreen aspect ratio. The rear camera shoots
video in 16:9 widescreen to match the 720p standard, although only the central 4:3 part of the
recording is shown on the screen during recording. The forward facing camera shoots in 4:3.
Apple A5 processor

The iPad 2 added a dual core Apple A5 processor that Apple claims doubles processing speed
and has graphics processing that is up to nine times faster than the previous iPad.

iPad with 3G + Wi-Fi



3G versions of the iPad 2 offer CDMA2000 support for customers using the device on a CDMA
network (e.g. Verizon Wireless in the United States) or GSM/UMTS support for customers using
the device on a GSM/UMTS network (e.g., AT&T Mobility in the United States or Orange in
Europe).

The iPad Wi-Fi + 3G model includes an A-GPS receiver for tracking the user's location given
permission. Also, the iPad 2 3G model includes a plastic cap-like band at the top on the back for
the 3G antenna. The metallic grille for the microphone is replaced with a matching plastic black
grille on the 3G model.

Size and weight

The device is 15% lighter and 33% thinner than the original iPad, it is thinner than the iPhone 4
by 0.5 mm. The Wi-Fi version is 1.33 lb (600 g). Both the GSM and CDMA versions (known
respectively as the AT&T and Verizon versions in the US) differ in weight slightly due to the
mass difference between the GSM and CDMA cellular radios, with the GSM model at 1.35 lb
(612 g) and the CDMA model at 1.34 lb (608 g). The size of the iPad 2 is also less than the
original iPad at only 9.50×7.31×0.34 in (241.2×185.7×8.8 mm), compared to the original iPad's
size at 9.56×7.47×0.5 in (242.8×189.7×13.4 mm).

Reception

The iPad 2 was met with positive reception for its sleeker design compared to the original iPad
and the iPhone 4, as well as the new A5 dual-core processor for improved performances and the
addition of a CDMA 3G model alongside the GSM 3G model, as well as its high capacity
battery. Despite the praise given to the iPad 2, reception towards the two cameras on the device
was mixed, comparing the quality of both cameras to the two cameras on the fourth generation
iPod touch, and noting that the screen resolution, which has remained the same, could have been
higher than its predecessor.
