Owners of the iphone and ipad that will install the latest version of Apple’s mobile operating system will see that some old applications will stop working.
The general movement affect the apps that were not updated in the last two years.
Even if many have been abandoned by their developers, owners continue to use some of them often.
This is a consequence of iOS 11 restricted to running applications that are written in what is known as 64-bit code.
The number indicates the amount of data a processor can handle at one time – the bigger the figure, the faster a computer can, potentially, operate.
Dropping support for 32-bit software allows Apple to streamline its operating system and allows you to perform more quickly than it does not need to load the libraries of software to make sense of the previous programs.
Apple has explained in the past that it is relatively easy for the app maker to modify its products, its App Store has rejected the updates that the lack of 64-bit support starting from June 2015.
Even so, the move of dollars a general trend for operating systems to support legacy software for long periods of time.
“Two years is a very short time for something to become obsolete, even in the technological world in which things move very rapidly,” said Prof Alan Woodward, from the University of Surrey in the computing department.
“What most vendors have done so far – and Microsoft is the biggest example of this is to keep things as compatible as possible for as long as possible.
“You have not taken a huge amount of work for iOS 11 to have continued to support 32-bit, so it is difficult not to conclude that Apple is really trying to force the pace and make the people move.”
IOS 11 update, should be released soon.
Many of the affected applications are from independent developers that have shifted their attention to other projects. However, the list also contains the software from multiple publishers, including:
various Disney products, including the Winnie the Pooh Puzzle Book, Tangled digital book, and the Princess & the Frog app
high-profile video games, including 2K’s XCom: Enemy within, and Gears of ” Flappy Bird
American Express (Amex UNITED kingdom-iPad
several Penguin Books app for children, including his Ladybug, I am Ready to Magic and Focus on the titles, as well as his spot Goes to School interactive book
Some of these products are still on sale on the App Store at the time of writing.
The IPhone and iPad, you can discover which, if any, products you will lose access to by going into their device Settings menu, by clicking on the button “, and then tap Apps in a whisper.
There are, however, the benefits for the installation of iOS 11.
Among them are:
support for the new augmented reality app that mixes together the graphics and the real-world views
a new App Store, which includes articles on some of the products and developers is equipped with
improved voices for Siri
a “do not disturb” feature that is activated when the device detects that it is used in a moving vehicle
“Of course, it is not necessary to upgrade to iOS 11, and, in theory, you could say that people have a choice,” said Prof Woodward.
“But, in practice, users are required to switch to the new version, assuming their products support it.”

64-bit v 32-bit: a brief introduction
The number of bits in relation to a microprocessor affects the size of the numbers that can be handled by its registers – the tiny bits of memory on the processing chip. These numbers are then used to address Ram (random-access memory).
In the case of a 32-bit architecture, the amount of memory that can be addressed by two to the power of 32, in other words 4.3 billion values.
In the case of 64-bit architecture of the processor, in theory, address 18,400,000 trillion values.
As a result, operating systems written for 32-bit chips can only access up to 4GB of Ram, but those written for 64-bit processors can, in theory, support up to 16 billion gigabytes of Ram.
If a program has been written to take advantage of a 64-bit operating system, it means that the processor can access data that is in this larger memory rather than retrieving from flash memory or a hard disk, which can speed up the entire processing chain.
However, including more Ram also makes the equipment more expensive and power-hungry. None of Apple’s iOS products, to date, has included more than 4GB of Ram.
