I. INTRODUCTION
ODAY'S mobile devices are multi-functional devices
capable of hosting a broad range of applications for
both business and consumer use. Like a computer
operating system, a mobile operating system is the software
platform that determines the functions and features available
on your device, such as thumbwheel, keyboards, wireless
security, and synchronization, messaging and more.
Some of the more common and well-known Mobile
operating systems are Google’s Android and Apple’s IOS
because of their Popularity we are going to talk about these
two operating systems which are commonly seen in market
and then compare them with each other.
1.1. Smartphone’s
A Smartphone is a mobile phone build on a mobile operating
system with more advanced computing capability and
connectivity than a phone. The first Smartphone’s combined
the functions of a Personal Digital Assistant (PDA) with a
mobile phone. Some other features,
Portable media players,
Compact digital cameras,
Pocket video cameras,
GPS navigation,
Web browsers,
Touchscreen,
Wi-Fi,
Mobile Broadband.
1.2. Smartphone’s OS
There are many Operating Systems for smart phones. The
main mobile operating systems (OS) used by modern smart
phones includes the following:
Google's Android,
Apple's iOS,
Nokia's Symbian,
RIM's BlackBerry OS,
Microsoft's Windows Phone.
Such operating systems can be installed on many
different phone models, and typically each device can receive
multiple OS software updates over its lifetime.
Android from Google and IOS from Apple provides not
only operating system but also provide a mobile development
platform because both of them are facing tough competition
against each other. Now we are going to talk about the main
operating system respectively android and IOS which are
commonly seen in market.

1.3. Android
Android, Inc. was founded by Andy Rubin. In 2005, Google
acquired it and then the team led by Rubin developed a
mobile device platform powered by the Linux kernel. Finally,
On the November 5, 2007 the Open Handset Alliance, a
business alliance of several companies which include Google,
HTC, Intel, LG and other 76 firms unveiled itself. On the
same day, the Open Handset Alliance also unveiled their first
product, Android, a mobile device platform which was built
on the Linux kernel version 2.6
[http://developer.android.com/guide/developing/tools/emulat
or.html].[1] And the first commercially available phone to
run the Android operating system was the HTC Dream,
released on 22 October 2008
[http://developer.android.com/resources/dashboard/platformv
ersions; http://developer.android.com/guide/basics/what-
isandroid.html].
Figure 2: Internal Architecture and Working
The diagram shows the components of the Android OS.
One of its most well known features is the applications
(apps). Applications are usually developed in the Java
language using the Android Software Development Kit, but
other development tools are available, including a Native
Development Kit for applications or extensions in C or C++.
Besides, by providing an open development platform,
Android offers developers the ability to build extremely rich
and innovative applications. Developers are free to take
advantage of the device hardware, access location
information, run background services, set alarms, add
notifications to the status bar, and much, much more. So, In
April 2011 Google said there had been about 100,000
Android apps installed. The Android OS is used on
smartphones, netbooks and tablets, including the Dell Streak,
Samsung Galaxy Tab, TV and other devices. And some
research company estimated in Q2 2009 that Android had a
2.8% share of worldwide smartphone shipments. By Q4 2010
it had grown to 33% of the market, becoming the top-selling
smartphone platform.
[http://code.google.com/p/openintents/wiki/SensorSimulator].
1.4. IOS
iOS is Apple`s mobile operating system. Originally
developed for the iphone, iOS now can also support other
Apple`s devices such as itouch, ipad and Apple TV. Although
it is derived from Mac OS X, iOS has the technologies that
are available only on itself, such as the Multi-Touch
interface and accelerometer support, and these
devices make iphone easier to use
[http://en.wikipedia.org/wiki/History_of_Mac_OS_X].[6]
The other great feature of iOS is its numerous applications.
According to the reference, iOS has more than 300,000
applications in Apple`s App Store, which have collectively
been downloaded more than 10 billion times. This can be
credited to the iOS software development kit (SDK), which
contains the code, information, and tools people need to
develop, test, run, debug, and tune applications for iOS.
However, loading an application onto the devices is only
possible after paying an iPhone Development fee [Buck,
2010]
II. SYSTEM ARCHITECTURE
2.1. Android Architecture
The Android architecture has several layers as showed in
Figure 3.
2.1.1. Kernel
Linux is support for core system services such
as security, memory management, process management,
network stack, and driver model
[http://thecoffeedesk.com/news/index.php/2009/05/17/iphone
-architecture/]. The kernel also acts as an abstraction layer
between the hardware and the rest of the software stack.
Figure 3: Android Architecture
2.1.2. Runtime
Runtime includes core libraries and Dalvik virtual machine.
Core libraries have a set of core libraries that provides most
of the functionality available in the core libraries of the Java
programming language. Every Android application runs in its
own process, with its own instance of the Dalvik virtual
machine. The Dalvik VM executes files in the Dalvik
Executable (.dex) format which is optimized for minimal
The SIJ Transactions on Computer Science Engineering & its Applications (CSEA), Vol. 1, No. 4, September-October 2013
ISSN: 2321 – 2381 © 2013 | Published by The Standard International Journals (The SIJ) 143
memory footprint. The VM is register-based, and runs classes
compiled by a Java language compiler that have been
transformed into the .dex format by the included “dx” tool.
The Dalvik VM relies on the Linux kernel for underlying
functionality such as threading and low-level memory
management.
2.1.3. Libraries
Android has a set of C/C++ libraries used by various
components of the Android system. These libraries are
exposed to developers. The system C library is a BSD-
derived implementation of the standard C system library. The
media libraries are based on PacketVideo’s openCORE
which support playback and recording of many popular audio
formats. The surface manager manages access to the display
subsystem and seamlessly composites 2D and 3D graphic
layers from multiple applications [Claudio Maia et al., 2010].
2.1.4. Application Framework
All Android applications are written with Java programming
language, it ships with a set of core applications including
email client, SMS program, calendar, maps, browser, contacts
and others. Android offers developers the ability to build
various applications with an open development. Developers
have full access to the same framework APIs used by the core
applications [Damianos Gavalas & Daphne Economou,
2011]. The application architecture is designed to simplify
the reuse of components; any application can publish its
capabilities and any other application may then make use of
those capabilities. This same mechanism allows components
to be replaced by the user. The applications including views
that can be used to build an applications, including lists,
grids, text boxes, buttons, and even an embeddable web
browser. Content providers enable applications to access data
from other applications or to share data with others. The
resource manager providing access to non-code resources
such as localized strings, graphics and layout files. The
notification manager enable all applications to display custom
alter in the status bar. The activity manager manages the
lifecycle of applications and provides a common navigation
back stack.
2.2. iPhone Architecture
Figure 4: iPhone Architecture
2.2.1. Hardware
In iPhone, Hardware refers to the physical chips soldered to
the iPhone’s circuitry. The actual processor falls under this
layer, but the instruction set and in-memory descriptor tables
are contained within the “processor” layer.
2.2.2. Firmware
Firmware refers the chip-specific code that is either contained
with memory in/around the peripheral itself, or within the
drive for said peripheral.
2.2.3. Processor
Processor is refers to the ARM instruction set and the
interrupt descriptor table as set up by the iPhone OS during
boot and driver initialization.
2.2.4. iPhone OS
iPhone OS is the kernel, drivers, and services that comprise
of the iPhone Operating System. It sits between the user
space and hardware.
2.2.5. Objective-C Runtimes
Objective-C runtime is comprised of both the Objective-C
dynamically-linked runtime libraries, as well as the
underlying C libraries.
2.2.6. Frameworks/API
Frameworks/API layer has API calls which are Apple-
distributed headers with the iPhone SDK, with some dynamic
linking occurring at runtime. These reside on top of the
Objective-C runtime, as many of these are written in
Objective-C.
2.2.7. Application
The application stored in iPhone has to be purchased through
the application store. This application was compiled to native
code by the Apple-distributed iPhone compiler, and linked
with the Objective-C runtime and C library by the linker. The
application also runs entirely within the user space
environment set up by the iPhone OS.
III. FEATURES WITH RESPECT TO VERSION
3.1. Android OS
The Android OS by Google is the most widely used platform
for smartphones and tablets on the market. It was introduced
as a collaborative effort from the Open Handset Alliance
(OHA), a unit that comprises companies such as Google,
HTC, Sony, Dell, Samsung, LG, T-Mobile, Motorola, and
many others. This is one of the reasons smartphones from
these companies are released with the Android OS. As a
result, the consumer has a wide variety of smartphones to
choose from. Compared to the iOS from Apple, Android
devices are far less expensive.
Jelly Beam [http://www.android.com/about/jelly-bean/],
or Android 4.1, replaced the ice cream sandwich OS (4.0)
The SIJ Transactions on Computer Science Engineering & its Applications (CSEA), Vol. 1, No. 4, September-October 2013

more ability to swipe their finger over the screen to perform
actions. It also performs faster than the earlier release. Jelly
Bean also makes it easier to share photos on social media
sites.

IV. MARKET ANALYSIS
Android market share 75% of smartphones, 3.7% of tablets in
North America (as of Jan'13) and 44.4% of tablets in Japan
(as of Jan'13). In the United States in Q1 2013 - 52.3%
phones, 47.7% tablets.
IOS market share 14.9% of Smartphone’s, 87%
of tablets in North America (as of Jan'13) and 40.1%
of tablets in Japan (as of Jan'13)
[http://www.SmartphoneANDROIDVsIOS/AndroidvsiOSDif
ferenceandComparisonDiffen.htm].
Android and iOS, the number one and number two
ranked Smartphone operating systems (OS) worldwide,
combined for 91.1% of all Smartphone shipments during the
fourth quarter of 2012 (4Q12).According to the International
Data Corporation (IDC) Worldwide Quarterly Mobile Phone
Tracker, Android Smartphone vendors and Apple shipped a
total of 207.6 million units worldwide during 4Q12, up
70.2% from the 122.0 million units shipped during 4Q11. For
calendar year 2012, Android and iOS combined for 87.6% of
the 722.4 million Smartphone’s shipped worldwide, up from
68.1% of the 494.5 million units shipped during calendar year
2011.The two horse race between Android and iOS has
collectively accounted for more than 50% share of the
smartphone OS market over the past two years
[http://www.idc.com/getdoc.jsp?containerId=prUS23503312]
Android continued its overall upward trajectory, reaching
triple-digit growth for the year. Samsung was the biggest
contributor to Android's success, amassing 42.0% of all
Android smartphone shipments during the year. Following
The SIJ Transactions on Computer Science Engineering & its Applications (CSEA), Vol. 1, No. 4, September-October 2013
ISSN: 2321 – 2381 © 2013 | Published by The Standard International Journals (The SIJ) 146
Samsung was a long list of vendors with single digit market
share, and an even longer list of vendors with market share
less than one percent. The intra-Android competition has not
stifled companies from keeping Android as the cornerstone of
their respective Smartphone strategies, but has upped the ante
to innovate proprietary experiences.
iOS posted yet another quarter and year of double-digit
growth with strong demand for the iPhone. But what also
stands out is how iOS's year-over-year growth has slowed
compared to the overall market. The smaller volumes during
2Q12 and to a smaller extent 3Q12 underscore the possibility
for a mid-year iPhone release in order to maintain market-
beating growth. Speculation about the release of possible
larger-screen and inexpensive models during the middle of
2013 continues to follow Apple, which would help sustain
growth. But until any model is formally announced,
speculation remains simply that

V. ANDROID AGAINST IOS
Today mobile market provides us with so many options that it
makes difficult for us to choose the best but as the saying
goes “that what is wanted more is the best” and the same goes
with our favorite Android. This Google’s OS came into
market in the year 2008 and before completing two years it
has shown a remarkable growth in the market. This is all
because of some reasons that I will try to elaborate in the
following discussion. These are the points that are the most
important that creates such a difference in my opinion. It is
changing the scenario in the world wide market as it is being
adopted by major players in smartphone market like HTC,
Samsung, Motorola, and Samsung and not to forget Google's
Nexus One. Android, because of its highlighting features is
competing against mobile platforms from Apple, Microsoft,
Nokia, Palm, Research in Motion and Symbian.
The android is growing faster than the iPhone. Its
platform is showing a rapid growth from the last two years
and the openness of the platform can account for this rapid
growth. The comparison of android and iPhone can be done
from different perspective but the final result is supposed to
be same foe each viewpoint. Here we discuss some of the
main features that make the difference between android and
iPhone.
5.1. Development Environment
5.1.1. Language
Google’s android provide a customized java virtual machine ,
and java byte code interpreter that facilitate android to offer
free services and make android to be a java platform thus
introduce a new development platform that influence
developers to create there application using java
programming whereas, iPhone has totally different approach
for development environment. It introduces a small scale
version of its desktop Mac OS X Cocoa. iPhone only
supports Objective-C language. Android’s popularity is due
to its open platform and availability of excellent developer’s
tools. Java and the Eclipse IDE are major attractive aspects of
Android to make it’s the best choice of developers. iPhone is
based on objective-C that is difficult to use and its
development platform is not properly defined. The
development environment of the iPhone is more tedious than
android’s. Almost all the standard Java IO, network libraries
are easily available.
5.1.2. Performance
Performance is one factor among many that defines whether
or not a platform will succeed. Performance comparisons
depend on many factors, here I am discussing the
performance of Android’s JVM vs. the iPhone’s Objective C.
Android is a Java based platform and uses a Java Virtual
Machine (Dalvik) to execute apps Java was considered to be
a slow and cumbersome platform. Java has been optimized
and now its performance is extremely fast. Dalvik has been
The SIJ Transactions on Computer Science Engineering & its Applications (CSEA), Vol. 1, No. 4, September-October 2013
ISSN: 2321 – 2381 © 2013 | Published by The Standard International Journals (The SIJ) 147
optimized even more for mobile devices, so now the Android
is one fast platform.
iPhone OS is written using Objective C, which is an
object oriented version of C that uses messages It’s like
having every phone call go through an operator who relays on
the message to the other person rather than just calling the
other person directly. There is a message passing system
called objc_msgSend(), is a critical piece of software for
anything written for OS X on the Mac or the iPhone.
5.1.3. Open Vs. Close (Platform Approach)
Apple offers a closed, proprietary system with peerless
marketing, an excellent user interface and strong ties between
hardware and software; Google prefers open-source approach
to develop new applications. The iPhone doesn't offer
background processing for third-party applications as
comparison to Android. It is much more open. One can build
any kind of application take benefit of any features. This is
one of the main features of android that shines
[http://www.darkreading.com/privacy/google-android-vs-
apple-ios-the-mobile-a/240157894].
5.1.4. Syncing
iphone users have to plug into the computers to do all sorts of
syncing but in android this can be easily done through Google
account.
5.1.5. Application Publication Charges
As apple provide a proprietary system the applications can't
be sold without Apple's approval, there cannot be
multitasking and also there is freedom to the user to duplicate
the features of the core apps. Both platforms take 30 per cent
of application revenues, although Android is free to sign up
to, while Apple charges developers $99 per year. To publish
their application on the apple store the developer need to pay
an annual fee of US$99 on the other hand android developer
has to pay only $25 fee to one time registration and also they
can publish the same application in other application market
there is no restriction for that.
5.1.6. Content
On the net the content and the information regarding iPhone
is not much as compared to Google’s android We can easily
get all the content, source code and information related to
android platform as and when required.
Android SDK is installed with the full information,
helping guide and APIreferences. It takes a few seconds to
found information regarding our queries. IPhone also
provides lots of resources that help developers to perform
their task but it takes much time to do that.
5.1.7. Browsing
In terms of internet browsing, which platform is better?
The answer is given by the researcher Neilsen.
According to data collected by him and compiled by
eMarketer, owners of Android phones are the most
likely to use their device's Internet functionality
[http://www.diffen.com/difference/Android_vs_iOS]. Ninety-
two percent of Androiders say they take utilize their phone's
Web connection, compared to 88 percent of iPhone owners.
Both devices are well above the curve for smartphone owners
in general, however, where the overall Net-using percentage
is only 71.
5.1.8. Security
There are some privileges on iPhone to restrict the addition of
new software for the users. Each application runs on a single
UNIX kernel. If there is some problem from running
application then whole system can be affected.
Whereas in android each application runs independently.
There are pre-defined permissions and authorizations for each
feature. So from security point of view android is much better
then iPhone for users.
5.1.9. Google Benefit
One another benefit of android is to make use of the facilities
that Google offers such as Google maps, Google voice,
Google documents and many more.

VI. CONCLUSION
After a long introduction of the basic concept of Android and
OIS it is very hard to predict that which is ahead in mobile
market, both are looking towards the future providing us to
more and more advances in our mobiles. So while choosing a
Smartphone does not follow the trend but to understand the
differences between Android and IOS about their advantages
and disadvantages which is supposed to be important when
purchasing a Smartphone.
We don’t care about who the winner is but about which
company’s software products and services are of our favor.
