3. HISTORY OF OPERATING
SYSTEM
 History of operating system is one of years of
experimentation.
 Operating system was absent in the first
commercial form of electronic computer
launched in 1940's. At that time
programming languages were not in use.
Naturally there was hardly any idea about
operating system.
 The next generation of computers was
introduced in the early phase of 1950's..

4.  It is a set of system software programs in
a computer that regulate the ways
application software programs use the
computer hardware and ways that user
control the computer.
 The OS provides certain services to
programs and to the users of the
programs
AN OPERATING SYSTEM

5. COMMON FEATURES OF OS
 Program Execution
 Providing Interfaces
 Handling Input / Output Operations
 Error Handling
 Memory management
 Process management

23. Microsoft Research
 Microsoft Research is huge. More than 1,000
scientists and engineers — including winners of some
of the most prestigious prizes in physics, computer
science and mathematics — develop new ideas and
try to solve global challenges with the use of
technology. Unlike many companies, Microsoft’s
research department is not just interested in ways to
improve their products now; Microsoft Research works
with academics all over the world on real scientific
challenges.
 If a problem can be approached with technology and
computers, there’s a good chance someone in Microsoft
Research is working on it. That is pretty awesome
REASON WHY MICRSOFT IS VERY
GOOD

24. Innovative Products
 Microsoft continues to create some of the most
innovative products around. They have a long history
of building things before their time, only for another
company to improve on their work at a later date and
succeed. If you can stick a smart in front of it, Microsoft
has developed it in the past: smartphones, smart TVs,
smart watches and tablets have all been preceded
by Microsoft products that came too early.
 Even when the time seems right, Microsoft has been
burned for being too innovative. The Xbox One is a
really great game console. Microsoft’s original vision
would have made it even better.

25. Innovative Design
 Microsoft has pioneered some innovative software
designs. Despite not reaching wide commercial
success Windows Phone is a great product. It managed to
be beautiful and modern at a time when Apple was still
heavily invested in faux-leather and baize. While iOS
is back on par with Windows Phone, Android still lags
behind with horrendous vendor skins layered on top of
an already ugly operating system
 Innovation does not necessarily imply success. With new
things, Microsoft has always been innovative, but not
always successful. Their continued willingness to push
despite failing in the past is remarkable .

27. Universal Software
 Microsoft Office is a must have if you are serious
about business, or work in a large office. While
you can substitute Microsoft’s Office suite for
personal use, Microsoft’s business applications
continue to dominate for professional purposes.
 Not only is Microsoft Office universal, it’s also
awesome. For example, Excel is a powerful
tool with which you can do a long list of
amazing things; it’s even possible to make an
RPG.

28. Backwards Compatibility
 Microsoft is a massively innovative and
forward thinking company, but they also
think backwards. No other software company
offers the level of backwards compatibility
that Microsoft do.
 The Windows team invests a mind-boggling
amount of time, hardware, and people into
maintaining compatibility.
 The fact you can run some of your old PC
games on a Windows 8 laptop with no issues,
let alone your important legacy business
software, is pretty damn awesome.

29. Bonus: They Listen
 Not many tech companies solicit feedback
from their customers. Apple, for example, is
famously infuriating to communicate with.
On the other hand, Microsoft is actively
seeking customer feedback.
 They’ve learnt from high-profile missteps and
they want your help to make better products.
A tech company letting you have your say?
That’s awesome.

30. CONCLUSION
 Microsoft officials believe they can use technology and
process improvements to make innovation happen more
rapidly and repeatedly
 Microsoft is thinking not just technologically, but also
organizationally, about its innovation process these days.
The various labs throughout the company are the conduit
between Microsoft Research and the PGs (product groups).
 Microsoft has done a lot of rethinking and revising in the
past couple of years as to how to bring innovations more
quickly to market.
 In my opinion, since the appointment of new CEO Satya
Nadella in 2014, I think Microsoft are sticking their necks
out to produce something genuinely new. Meanwhile, Apple
seem to be merely improving upon preexisting ideas by that
all important 5% or 10% that makes all the difference. The
key to their success is perfecting the recipe, not in
producing an entirely new dish.
