 An operating system (OS) is an interface between
hardware and user. It manages hardware and
software resources of the system.
 An operating system which controls mobile devices is
called Mobile OS. They are simple and deal with the

3. Various Famous Mobile Os.
 There are some famous Mobile operation systems are

4. Android
•This is a mobile Operating
System developed and
operated by Google Inc.
•This Os is originally
developed for the location
based service provided with
a unique user interface.
•It is an open source Os. But
with some Google terms
condition. Separate
development of the os is
possible but distribution is
not possible via Google
authorization.

5. iOs
•This Os is developed and
distributed by Apple Inc.
•Many apple devices such
as iphone,ipad and ipod
are powered by this Os.
•According to apple
according to some security
researchers ios is packed
with tons os security
features.

7. Dalvik Virtual Machine
 Android os Run on the ARM based chipset devices.
 As Android devices use java for core programming
process it is to have JRE(Java Run Time Environment).
 But Instead of using JRE android use A specialized virtual
machine called Dalvik.
 This virtual Machine is optimized to run java code and
Make a link between hardware and core of android
system.

8. Kernel (Brain of Os)
•The kernel is the main
component of most mobile
operating systems; it is a
bridge between applications
and the actual data
processing done at the
hardware level.
•Almost every mobile has
different types of kernel
installed on devices.
•Android uses linux kernel to
execute various operations.
•Kernel contains hardware
drivers, Memory location
Information, automatic logic
unit, power management
units. ect.

13. Installation or Modification
of Os.
 Unlike Computers and Laptops installation or
modifications of installed mobile os is difficult.
 Every Mobile devices contains their hardware
information in kernel and kernel is part of os.
 If you want to install or modify your mobile os you
need to have access of superuser.
 Some Mobile phone carriers and even some regions
declared this process as illegal.
 Like you heard “Rooting”, “jailbreaking” etc.

14. Another way….
 Even though modification or installation is difficult and
little dangerous process some time we need to access
core part of os(ROOT) for maintenance or
development purpose.
 Os developer companies create some tools for their
own use to gain temporary “Super user” acces.
 Individual mobile manufacture companies also made
some of this kind of tools generally knows as
“FLASHTOOLS”

15. Android and ios tools.
 Although individual Mobile companies create their
own flashing tools. But there is a common command
line operation tool is available for all android phones.
 This is called “adb” = “Android debugger bridge”.
 adb is a set of command line operation for gaining full
access over your android phone.

16. Android and ios tools.
 In ios getting gaining the superuser access is called
“Jailbreaking”.
 A custom binary made by hackers is neseccery for
flashing or jailbraking process.tools like “RedSn0w”,”
Pwnage tool” are used for above purpose.

17. Firefox Os.
1. Firefox os is linux based
operating system.
2. It is developed by
Mozilla a non-profit
organization.s
