OPERATING SYSTEM
An essential component of computer system
An interface between user and system
A software that provides common service for
computer programs
Manages computer hardwares and softwares
Application softwares require Operating System
to function
OPERATING SYSTEM
Acts as an intermediate between programs and hardwares for
input/output and memory allocation
Any device having an computerized system has an Operating
System
Ex:-cellular phones ,Game console ,super computers & web
servers
Examples of some popular modern operating systems are:-
Microsoft Windows ,Mac OS X ,Linux ,UNIX , Android ,Windows
Phone, iOS etc.
TYPES OF OPERATING SYSTEM
Real Time
Distributed
Multi User
Templated
Embedded
MOBILE OPERATING SYSTEM
An operating system that operates mobile devices
Combines features of personal computer OS with cellular and other features required for a mobile deice user
OPEN SOURCE
A computer program in which the source code is available to the
general public
General public has right to modify, re-distribute and re-invent.
Main principle is peer production by collaboration with end
product blue prints
And to avail documentation an no cost to the public.
Most of the open source mobile operating systems are based on
LINUX kernel
KERNEL
Fundamental part of modern Operating
Systems
Manages input/output from softwares
The part of operating system that directly
interacts with hardwares
Translates signals into data processing
instruction for the CPU and other
components.
Decides which programs should be
allocated to which process
ANDROID
ANDROID OS
Mobile OS based on Linux kernel
Primarily developed for mobile devices
Was unveiled in 2007 along with the
foundation of Open handset Alliance
INVENTION & DEVELOPMENT
Invented by Andy Rubin in 2003
Android Inc. was founded by Andy Rubin, Rich Miner, Nick Sears and Chris White
Google acquired Android in 2005
In 2006 a version with code name “Sooner” was released.
On 5th November 2007, Open handset Alliance was founded by taking Google along with handset makers HTC, Samsung ,Sony Wireless service providers Nextel, T-Mobile, and Chipset makers Qualcomm and Texas Instruments.

ANDROID APPS
Apps are developed by using Android SDK
It uses Java programming language
But now, using Android NDK and Eclipse IDE
Android apps can be developed using C/C++
Before that ADT needs to be installed
ANDROID APPS STORES
Amazon App Store Mobogenie
ANDROID APPS STORES
As per a blog post by Larry Page, 50
billions apps were installed in Google
Play till June 2013
ANDROID KERNEL
Android is based on LINUX kernel
Kernel is written in C & C++
Android kernel is also called
Monolithic/Modified LINUX Kernel
First Android Kernel version was Ver. 2.6.25
Current Android versions run on LINUX kernel
Ver. 3.4
ANDROID KERNEL
MULTI-PLATFORM USE
Android was first developed as open source
mobile OS
But currently also being used in other platforms
Android Wear, Android TV etc. are used in
Smart watches and Televisions
Android is also used in PCs and game consoles

INTRODUCING FIREFOX OS
UBUNTU TOUCH
UBUNTU TOUCH OS
Mobile version of popular Ubuntu operating system
Developed by Canonical UK Ltd. and Ubuntu community.
Primarily designed for touch screen mobile devices such as smartphones
and tablet computers
Ubuntu 14.04 support for mobile devices was announced by Mark Shuttle
Werth on 31st October 2011
