Android was founded in 2003 by Andy Rubin, Nick Sears, Chris White, and Rich Miner. It was later acquired by Google in 2005. Major releases include Cupcake in 2009 which added video recording, Donuts in 2009 with multi-touch gestures, Froyo in 2010 with widgets and tethering, Gingerbread in 2010 with copy/paste and a virtual keyboard, Honeycomb in 2011 designed for tablets, Ice Cream Sandwich in 2011 with a unified Android for phones and tablets, Jelly Bean in 2012 with Google Now and lock screen customization, KitKat in 2014 with transparent bars and gestures, and Lollipop in 2014 with a new UI design and runtime.
Android was founded in 2003 by Andy Rubin, Rich Miner and Nick Sears to develop software for mobile phones. In 2005, Google acquired Android Inc. and continued developing the Android operating system. Android uses a touchscreen interface based on direct manipulation gestures and incorporates sensors like accelerometers and gyroscopes. While developed privately, Google releases the source code publicly for select devices to build upon. Android consists of a Linux kernel with Java-compatible libraries and APIs for building applications. It is designed to minimize power consumption by suspending unused apps in memory. Beyond phones and tablets, Android powers devices like smart TVs, watches and glasses.
An operating system (OS) manages computer hardware and software resources, performing tasks like memory management, process scheduling, and file management. Early computers did not have operating systems, but tools for system management emerged quickly. Major concepts in OS development included supporting an entire product line with a single OS, like IBM's OS/360, and time-sharing, which allowed multiple users to share expensive computers simultaneously. As microcomputers evolved, minimal OSes were developed for early models, while MS-DOS became widely popular through its inclusion with the IBM PC. By the 1990s, more robust OSes with graphical user interfaces became desirable, leading Microsoft and Apple to develop Windows NT and Mac OS X respectively based on Unix.
The document provides a history of operating systems, beginning with the creation of UNIX at Bell Labs in 1969. It describes how UNIX was rewritten in C in 1973 and some of its key authors. It discusses the development of commercial Unix systems, BSD, and Linux and major distributions like Slackware, Debian, and Red Hat. It also references the GNU project and development of the GPL license, and how these led to the rise of free and open source software.

The document provides an overview of operating systems, describing their basic functions and evolution over time. It discusses the four main subsystem managers that work together to control hardware, memory, processors, devices and files. Operating systems have evolved from large mainframes to support various hardware from mobile devices to supercomputers, and different types including batch, interactive, real-time and embedded systems. The history and increasing complexity of operating systems is also summarized.
Before operating systems, programmers had to manually reconfigure wiring and connections to run different programs on a computer. Early operating systems used punch cards or magnetic tapes to load programs into memory one at a time, wiping out the previous program. The first "boss" programs or operating systems allowed multiple programs to run simultaneously by controlling the other programs. One of the earliest operating systems for personal computers was Microsoft's MS-DOS, which required typing commands instead of using a graphical user interface. Later, operating systems incorporated mouse input and clicking interfaces instead of only text commands.
The document discusses the history of operating systems and the generations of computers. It covers 4 generations from the first to fourth generation. The first generation used vacuum tubes and had no operating systems. The second generation used transistors and was when operating systems were first introduced. The third generation used integrated circuits and the fourth generation uses VLSI and saw the rise of networks like LAN and WAN.

The document introduces operating systems, describing their basic roles and software and hardware components. It discusses the major subsystem managers in an operating system and their functions. It also outlines the evolution of operating systems over time from batch systems to current systems supporting multimedia, internet access and client/server computing. Current trends include object-oriented design, reorganized kernels, and multiprocessing configurations.
The document summarizes the history of operating systems through four generations:
1) The 1940s saw the earliest computers which had no operating systems and programs were entered manually.
2) In the 1950s, the first operating systems were developed and systems generally ran one job at a time via batch processing.
3) The 1960s introduced multiprogramming which allowed multiple jobs to run simultaneously by switching between them. Techniques like spooling and time-sharing were also developed.
4) The fourth generation saw the rise of personal computers powered by microprocessors, with MS-DOS and UNIX becoming the dominant operating systems.
This document compares and contrasts Android and iOS mobile operating systems. It discusses their market shares, developer platforms, security features, operating system upgrades, and app approval processes. Key differences noted are that Android has a more open development platform but greater fragmentation, while iOS has a more restrictive controlled environment but a more stable and consistent user experience. The document provides references for further information on comparisons between Android and iOS.

5. HISTORY OF Operating Systems
Android : The development of Android started in 2003
by Android. which was purchased by Google in 2005. The
Fast version is ALPHA(1.0) but we can’t get it but the
second version BETA(1.1) released on November 5, 2007.
After that we got so many updates now we are using
Android LOLLIPOP(5.1) .
IOS :On June 29, 2007, Apple released the first version of
iOS 1.x series release was 1.1.5. Now we are using
iOS 8.3
Windows : Windows Phone (WP) is a family of mobile
operating system developed by Microsoft for Smartphone
the fast windows phone comes with Windows 7 which is
released publicly on November 8, 2010 in the U.S. And now
we r using 8.1 but we get update windows 10.

7. About Android
Android (based on the Linux Kernel) is
from Google Inc. It has the largest installed base
worldwide on Smartphone's. Most of Android
is free and open-source software.
8.
9. iOS (originally iPhone OS) is a mobile operating
system developed by Apple Inc. and distributed
exclusively for Apple hardware. It is the operating
system that powers many of the
company's iDevices.
10.
11. Windows Phone (WP) is a family of mobile
operating systems developed
by Microsoft for smartphones as the replacement
successor to Windows Mobile and Zune.
Windows Phone features a new user interface
derived from Metro design language. Unlike
Windows Mobile, it is primarily aimed at the
consumer market rather than
the enterprise market.
13. Android Windows
OS
iOS
The most recent
version of Android
offers something
different and enticing in
the form of highly
customizable home
screens – a feature that
iPhones never support.
Windows 8 has the
most innovative
mobile UI – it has
taken the concept
of live tiles to a
different level by
adding interactivity.
Apple iOS 6 is bound
to follow it tried and
tested formula of
keeping things simple.
Every new iOS
version has added
better functionality to
the user interface,
making the UI intuitive
and easy to operate.
Comparison of User Interface
16. Apps
We can bump Windows Phone straight out of the
running here because it trails way behind Android and
iOS when it comes to overall app numbers and app
quality.
Android apps – 1.3 million
iOS apps – 1.2 million
Windows Phone apps – 300,000
Traditionally iOS has been a more lucrative platform
for developers and easier to develop for, so there has
been a tendency for new apps to appear there first,
but that is changing as Android’s market share
continues to grow. The Play Store still has a higher
percentage of free apps than the App Store, but in
terms of variety and quality we have to give this one
to iOS.
18. OS Updates
All three platforms are updated on a pretty regular basis.
There are big releases with new features and occasional
redesigns every few months, and smaller releases to deal
with bug fixes a little more frequently than that. Microsoft
and Apple maintain greater control over the software, so
it’s easier for them to roll out updates and compatible
devices tend to upgrade to the latest version in a timely
fashion.
Apple always leaves behind a couple older devices each
year when new software comes out, so it’s not entirely free
of fragmentation, but it does better than Microsoft or
Google. For example, Windows Phone 7 devices can’t be
updated to Windows Phone 8. If you opt for a Nexus
Android device then you’ll get the latest updates quickly,
but if you don’t, you may never get an update. Samsung,
Sony, and LG have finally begun providing some updates,
but you’re at their mercy, and the mercy of your wireless
carrier, which also has decided that it should have the right
to test and release all new software updates for Windows
20. Basic calling and messaging functionality is
good on all three platforms. Google has made
moves to fold everything into Hangouts, so
you can send messages via Wi-Fi, data
network, or SMS. You can also make video
calls online. FaceTime and iMessage are
basically exactly the same thing on the iOS
platform. Skype is Microsoft’s answer, but it’s
separate from your standard SMS. Skype
works on every platform; Hangouts doesn’t
work on Windows Phone; iMessages and
FaceTime are only for iOS and Mac OS X.
Calls and
messaging
22. Much has been made of the supposedly “toxic hell stew” that is Android, but
the threat of malware is grossly exaggerated by the competition. The truth is
that most people will never encounter a problem because they don’t go
outside the Play Store for apps. Specific manufacturers like Samsung have
taken extra efforts to beef up security for the enterprise market.
Apple is already firmly entrenched in corporate America and has also
worked on improved security for general consumers, most notably with the
Touch ID. The tight oversight that Apple has on apps and the ability to push
updates out to more devices, more quickly, gives it a definite edge over
Android.
Windows Phone is not as widely used, and that means MDM programs
focus on iOS and Android, but Microsoft is certainly working to improve
security and woo the business world.
Security
25. Maps
All three platforms offer a good maps solution,
despite what you’ve heard. Key features are
pretty similar, you can download maps for offline
use, get accurate estimates based on current
traffic conditions, and turn-by-turn directions for
driving or walking. They all work well and should
get you where you’re going. Still, the scale and
quality of Google Maps is unsurpassed. It has
more points of interest and it is generally more
detailed than Bing Maps or Apple Maps, but the
accuracy can vary from place to place.
27. This is another area where Apple extracts maximum value
from the hardware it offers. The 8-megapixel camera in the
iPhone 6 has been numerically surpassed by Android phones
like the Samsung Galaxy S5 and Windows Phones like the
Nokia Lumia 1020, but there’s more to a great camera than
just the megapixel count. Apple does the best job capturing
lighting, coloring, and other details.
The camera apps on each platform are very good and very
fast. For ease of use and best results without tweaking, the
iOS camera app takes the cake. There’s more variation on
Android simply because OEMs tend to add their own camera
apps with lots of features, some good, some a bit gimmicky,
but we’d take Apple’s camera any day of the week.
Camera
29. Apple doesn’t make budget devices, and the latest iPhone is always among the most
expensive handsets on the market, costing $200 with a two-year contract and $650
without. Last year’s iPhone 5S comes in at $100 less. The iPhone 5C — which is a
lot better than you’d guess — is as close as Apple gets to budget at about $200
cheaper, but it’s still pricey.
Microsoft’s main hardware partner Nokia (which it now owns) has always been good
at producing quality hardware at relatively low prices. There are a wide range of
Windows Phones at varying price points, and finally a few that push the limit and rival
Android and iOS on specs. It’s also worth remembering that hardware manufacturers
like Samsung, ZTE, LG, Lenovo, and Huawei are signed up as Windows Phone 8.1
partners and could well produce some cheap handsets in the near future.
Still, for sheer scale and variety nothing competes with Android. There’s a huge
choice of low cost handsets from a wide variety of different manufacturers and the
platform has been deliberately optimized to run on low end hardware. The fact that
Android also leads the field in free apps makes it the natural choice for the budget-
conscious. Chances are, if it’s a smartphone by HTC, Samsung, Sony, ZTE, Huawei,
or LG, it’s running Android.
Affordability
