that you must know about Ice CreamSandwich. First, Ice Cream
Sandwich is not a food that you can eatas a dessert. For people who
knows about nowadays technology,they know that Ice Cream Sandwich,
is a type of operating system. Second, Ice Cream Sandwich is a
nickname of an operating system,Android 4.0 used in smartphone,
mobile phone, and tablet. Inthese, Ice Cream Sandwich is used to
control hardware function ofyour device and provide general
services of your applications. Last, you must know why Android 4.0
is called Ice CreamSandwich, its because Androids major update all
have dessert codenames starting in alphabetical order. They are
Cupcake, Donut,Eclair, Froyo, Gingerbread, Honeycomb, and Ice Cream
Sandwich.Latest OS is Jelly Bean which is the fastest and smoothest
version ofAndroid yet. 9. Refined, evolved UI Refined animations
and feedback throughout thesystem make interactions engaging and
interesting. An entirely new typeface optimized for high-resolution
screens improves readability and brings apolished, modern feel to
the user interface. Virtual buttons in the System Bar let
younavigate instantly to Back, Home, andRecent Apps. 10. Continue .
Multitasking is a key strength of Android and its madeeven easier
and more visual on Android 4.0. TheRecent Apps button lets you jump
instantly from onetask to another using the list in the System Bar.
Rich and interactive notifications let you keep inconstant touch
with incoming messages, play musictracks, see real-time updates
from apps, and muchmore. 11. Android 4Multitasking 12. Resizable
widgets Home screens in Android 4.0 are designed to be content-rich
and customizable. You can do much more than add shortcuts you can
embed live application content directly through interactive
widgets. Widgets are resizable, so you can expand them to show more
content or shrink them to save space. 13. New lock screen actions
The lock screens now let you do more without unlocking. From the
slide lock screen, you can jump directly to the camera for a
picture or pull down the notifications window to check for
messages. When listening to music, you can even manage music tracks
and see album art. 14. Quick responses for incoming calls When an
incoming call arrives, you can now quickly respond by text message,
without needing to pick up the call or unlock the device. On the
incoming call screen, you simply slide a control to see a list of
text responses and then tap to send and end the call. You can add
your own responses and manage the list from the Settings app. 15.
Improved text input andspell-checking The soft keyboard in Android
4.0 makes text input even faster and more accurate. Error
correction and word suggestion are improved through a new set of
default dictionaries and more accurate heuristics for handling
cases such as double-typed characters, skipped letters, and omitted
spaces. Word suggestion is also improved and the suggestion strip
is simplified to show only three words at a time. 16. Powerful
voice input engine Android 4.0 introduces a powerful new voice
input engine that offers a continuous "open microphone" experience
and streaming voice recognition. The new voice input engine lets
you dictate the text you want, for as long as you want, using the
language you want. You can speak continously for a prolonged time,
even pausing for intervals if needed, and dictate punctuation to
create correct sentences. 17. Control over network data Mobile
devices can make extensive use of network data forstreaming
content, synchronizing data, downloadingapps, and more. To meet the
needs of you with tiered ormetered data plans, Android 4.0 adds new
controls formanaging network data usage. In the Settings app,
colorful charts show the total datausage on each network type
(mobile or Wi-Fi), as well asamount of data used by each running
application. Based onyour data plan, you can optionally set warning
levels orhard limits on data usage or disable mobile data
altogether.You can also manage the background data used
byindividual applications as needed. 18. Control over network data
Data usage controls let you monitor total usage by network type and
application and then set limits if needed. 19. OTHER FEATURES Fast
& smooth Seamlessly take and share photos. Android Beam The new
Google experience on Android-Voice Search. 20. Google Experience
Google Now brings you just the right information at just the right
time. A new look for Search i.e. VOICE SEARCH 21. Continue .
Redesigned Gallery app with photo editor Live Effects for
transforming video Powerful web browsing Android Beam for NFC-based
sharing Face Unlock Wi-Fi Direct and Bluetooth HDP . 22.
Limitations : First, the disadvantage is face unlock. Face unlock
isthe new feature from operating system ICS. Thedisadvantage is,
smartphone can be opened bysomeone using a photo of smartphone
owner . Second, the disadvantage is minimum requirement.For using
Operating System Ice CreamSandwich, smartphone must be have minimum
1Ghzprocessor and 512 MB RAM. The other disadvantage of Android 4.0
is that olderAndroid devices will not be upgradable to the IceCream
Sandwich. 23. Google Android Sales to Overtake iPhone and Tablets
bythe end of 2012. Intel doesnt want to lose ownership of the
netbookmarket, so they need to prepare for anything,
includingAndroid . Android was developed with multiple-processor
utilization inmind. Its simple for Android developers to program
for a phonewith 2, 4, or even 32 processing cores without having to
write asingle extra line of code. By the end of 2012, new devices
will be released with up toeight processing cores with clock speeds
in excess of 2 GHz.This means longer battery life, as a phone with
multiple corescan do more calculations quicker with less
energy.More Androiddevices are coming and some will push the
envelope even 24. Conclusion All-in-all, I would say that the
latest offering fromAndroid, the Android 4.0 Ice Cream Sandwich
isdefinitely worth more than just a look. Offering varietyof
powerful features and functionalities, this is onemobile platform
that developers are going to love todevelop apps for. By and by,
there will be more devices powered byAndroid 4.0 and that is when
its true potential will befully released to the world. 25. WHATS A
RETINA DISPLAY? High Resolution Screen Technology introduced
byApple. Provides greater pixel density and higher contrastratios.
The term is used for several Apple products, includingthe iPhone,
iPod Touch, iPad, and MacBook Pro. The displays are manufactured by
different suppliers.Currently, the iPads display comes from
Samsungwhile LG Display make the MacBook Pro display, alongwith the
iPhone and iPod Touch displays . 26. Retina Display SO IT MAKES
STUFF LOOK MAGICALLY BETTER . 27. FEATURES The sharpest, most
vibrant, highest-resolution phonescreen ever. Everything you see
and do on iPhone 4S looks amazing. Thats because the Retina
displays pixel density is so high, your eye is unableto distinguish
individual pixels. Which means text in books, web pages, andemail
is crisp at any size.Images in games, movies, and photos popoff the
screen. And everything is sharper. 28. Continue No detail
overlooked.By developing pixels a mere 78 micrometers wide,
Appleengineers were able to pack four times the number of
pixelsinto the 3.5-inch (diagonal) screen found on iPhone 4S
andiPhone 4. The resulting pixel density 326 pixels per inch makes
text and graphics look smooth and continuous atany size. 29.
Continue . Overlook 30. Continue Brilliant no matter how you look
at it.The Retina display uses technology called IPS (in-plane
switching) the same technology used in the Apple LED Cinema Display
and iPad toachieve a wider viewing angle than on typical LCDs.
Which means youcan hold iPhone almost any way you want and still
get a brilliant picture. In addition, the Retina display offers
four times the contrast ratio of previous displays, so whites are
brighter, blacks are darker, and everything is more beautiful. 31.
Continue IPS 32. Continue Advancements in the glass And under it.
Made from the same materials used in helicopters andhigh-speed
trains, the Retina display glass is chemicallystrengthened to be
harder, more scratch resistant, andmore durable than ever. The
glass also features an oil-resistant coating that helps keep the
screen clean. The Retina display includes LED backlighting and
anambient light sensor that intelligently adjusts thebrightness of
the screen for optimal viewing and batterylife. When you lift
iPhone to your ear for a phone call, aproximity sensor immediately
turns off the display to savepower and prevent accidental dialing.

to Implement (minimal code). Try Limiting to High Traffic Areas.
Can be Labor Intensive. Increases Bandwidth Usage. Impact on Future
of Web??? 35. QUESTIONS???
