The operating system is one of the most popular mobile operating system that is currently
available. The user interface that is implemented in iOS is based upon the technique of direct
manipulation. There are multi-touch gestures that were launched in the mobile industry by iOS.
There are also a number of accessibility features that come implemented in iOS for differently-
abled people [2].
Technical Features
The architecture of iPhone iOS is as illustrated and described below. There are five different
layers that are present in iOS. The layers that are present in the architecture of the operating
system enable it to carry out the operations and activities. The technical capabilities of the OS
are based upon the presence and inter-connection of these layers [3].
iPhone iOS Architecture [4]
Cocoa Touch Layer
The top most layers that is present in the architecture of iOS is the Cocoa Touch layer. The
frameworks that are very commonly used by the application developers and are implemented in
the iPhone are included in this layer. The standard Mac OS X Cocoa Application Programming
Interface is used to write this layer and it is written in Objective-C language.
Media Layer
The second layer from the lop that is present in the iOS architecture is the Media Layer. A
8

number of different media elements and capabilities such as the ones associated with audio,
video, graphics and likewise are included in this layer. There are also various frameworks that
are put in this layer for the development of the iPhone applications [5].
Core Services Layer
Core Service layer is placed at the third place from the top. The foundation on which the layers
above and the layer below are placed is provided by this layer which comes in the centre of the
architecture.
Core OS Layer
The fourth layer that is present in the iPhone iOS is the Core OS layer and it comes just above
the hardware/device itself. A number of different services come under the operations of this layer
such as low connectivity services, management of the memory, handling of the file systems,
connectivity with the external accessories and likewise.
iPhone Hardware
There are technologies that are required to be implemented for the hardware and the devices to
function correctly. iOS comes with this layer for the implementation of the required technologies
in the device.
Advantages of iOS
 Multitasking: One of the most significant advantages that is offered by iOS is the multi-
tasking feature that comes enabled with it. There are a number of different operations
that the user can perform and carry out all at once. Activities such as using a social media
application, using calculator, browsing the Internet and many more can be done without
any performance issues. Apple’s iPhone is being used by the home and business users for
a number of different purposed. This features leads to consumption of lesser time for the
execution of operations [6].
 Enhanced Security: There are a number of security risks and concerns that are observed
in association with the security of the mobile devices and the information that is present
in these devices. However, in case of iOS, there is an enhanced form of security that is
9

implemented in the devices. System securities are maintained through system software
authorization and secure boot chains. There is data protection that is implemented in the
iOS applications which are also safeguarded by app code signing and runtime process
security. The data and information is also encrypted to protect the same from security
risks and malicious usage. There are also a number of network based attacks and the
device security attacks that are executed. With the use of an iOS device, such attacks and
risks are also avoided [7].
 Better Integration: The hardware and software integration that is provided in the iPhone
with the aid of iOS is better as compared to most of the competitors. Taptic engine that
comes along with iOS provides the users with the ease of access and the ease of
notifications as well. The sensitivity levels can be easily adjusted and the information
regarding the applications can be obtained just by a long press or a single click on the
icon.
 Easy Updates: As soon as the company releases a system update, it becomes available to
all the Apple phones irrespective of their versions. This allows the users to come at par
with the latest technology and the latest elements in terms of the applications and the
security.
 Excellent Support and Help: The support, help and maintenance activities that are offered
along with the iOS are excellent in terms of 24x7 support and quick resolution to the
complaints and queries from the users [8].
 Variety of Applications: There are thousands and millions of applications that are
available for free of cost or on a paid medium on the App Store which comes pre-
installed in any of the iOS based device. The applications that are available on the store
include apps from various different categories such as games, social media, news,
entertainment, education, technology and many more. These applications can be obtained
with the aid of an iCloud id and can be easily installed in the devices. The users can also

Disadvantages of iOS
 It is impossible to jailbreak the latest version of iOS which is iOS 10. Apple just adopted
the rootless security system that does not allow the users to jailbreak their devices. There
are application developers and programmers that may require the jail breaking of the
device which comes as a huge challenge and an issue in case of iOS.
 The battery life that comes along with iPhone and other iOS based devices is an issue.
There are users who have lodged queries and complaints regarding the early battery
draining issues and problems. This becomes even more challenging for the business users
and the users that travel a lot. Short battery life may lead to challenges in the business
continuity that may be carried out with the aid of an iPhone [9].
 Connectivity with the non-iOS devices is also one of the major challenges that come
forward in case of these devices and operating systems. There are other mobile operating
systems and the devices that run on these operating systems that are available in the
market. For instance, android is one of the most popular mobile operating system and
there are millions of devices that run on the same. However, the connectivity of iOS
devices with the non-iOS devices is not easy to establish. Compatibility with the other
devices is considered as one of the major drawbacks of this operating system.
 In the latest version of the operating system, there are issues of crash and reboot that have
been reported. The device reboots itself in the middle of the operation that causes
deteriorated user experience. The data that is present in the device may also get deleted
during the system update to the latest version of iOS [10].
Conclusion
Users in the present time are using mobile devices and applications for different purposes and
activities. There is hardly any individual present that does not make use of mobile devices such
as Smartphones and tablets. For the functioning of these devices, it is necessary to have a
platform in the form of system software to present the users with the user interface and
capabilities to be executed on the devices. One of the most popular mobile operating system that
is available in the market is iOS operating system. It is a product of Apple Inc. and has taken the
market by storm since its launch in 2007. There are a number of innovative and interesting
