2. 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

3. 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.

4. TYPES OF OPERATING SYSTEM
Real Time
Distributed
Multi User
Templated
Embedded

5. 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

6. 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

7. KERNEL
 Fundamental part of modern Operating
Systems

interacts with hardwares
 Translates signals into data processing
instruction for the CPU and other
components.
 Decides which programs should be
allocated to which process
