Computer science faces many challenges as technology expands. Mobile and cloud computing, data security, and networking all require improvements to handle growing data and usage. By 2020, the digital universe could contain 40,000 exabytes of data, requiring better analysis tools and data visualization. While these issues seem daunting, addressing problems in areas like healthcare data could help improve treatment of diseases.

2. ABSTRACT
• Computer science is faced with many challenges as the digital universe
expands.
• From mobile and cloud computing to data security, addressing these issues
can require large, structural changes, but an examination of these problems
can lead to organizational solutions and improvements in the world.

3. CHALLENGES IN COMPUTER SCIENCE
• More employees and customers are using mobile technology. A switch to cloud
services and an emphasis on mobile platforms are essential.
• The Internet’s infrastructure will need to be updated to match the “New Internet.”
• 80% of security professionals rated data leaks and exposure of sensitive
information as the highest concern.

4. STEPS TOWARD SOLUTION
Changing the architecture of organizational networks can seem daunting. Below
are suggested steps.
• Identify and remove bottlenecks, improve routing patterns, and utilize better
servers.
• Use software-defined networking to allocate resources and increase data
efficiency.
• Change 10GB fiber optic cables to 100GB.

OF
THINGS

10. Internet of Things is an
infrastructure of uniquely
identified objects in the
internet or tied to the
internet, such as with RFID
or QR codes – both of which
are becoming more
prevalent with mobile
devices
USEFUL BENEFITS OF
INTERNET OF THINGS
Examples of “things” or
machines communicating
with each other (M2M) that
would contribute to the
Internet of Things include
almost anything that can be
attached with a sensor, be it
short range or long range
from smartphones to cars to
satellites.
By 2020,it is projected that there could be up to 100 billion
uniquely identifiable objects connected to the internet

15. NETWORKING
&
SPEED

16. With the rapidly
growing data traffic
comes an increased
need for speed, scale
and mobility
Solution
1
Smaller simpler solutions include identifying
and removing bottlenecks, improving bad or
sloppy routing paths and utilizing better
servers with improved space and bandwidth
usage
Solution
2
Another solution to use the network smarter
with the help of software-defined networking
that allocates network resources and
increases data efficiency
Solution
3
When both of those are exhausted and the
rapid data growth exceeds the speed and
resources available now, there will be calls for
changes to the global networking
architecture- changing the 10GB fiber optic
cables to 100GB fiber optic cables

17. BIG DATA
Big Data is so massive
that it outpaces human
understanding and
technology
AND
THE DIGITAL UNIVERSE

18. BIG DATAAND THE DIGITAL UNIVERSE
As organizations improve networking and infrastructure, an explosion of data
will lead to more problems with rewarding solutions.
• By 2020, the digital universe will grow from 130 to 40,000 Exabytes.
• The data that requires protection will grow by 40%.
• Data will become more complicated and harder to secure, store, and analyze.

19. 33%

Estimates that by 2020 as much as 33%
of the digital universe will contain
information that might be valuable if

will be essential in order
to improve processing
and analyzing the
information available in
Big Data
TYPES OF DATAARE BECOMING MORE COMPLEX
Unstructured text, audio, video, and other forms

21. CHALLENGES OF DIGITAL UNIVERSE AND BIG DATA
Cloud Computing
• 40% of information in the Digital
Universe “Touched” by Cloud
Computing providers by 2020
• High cost of implementation
• Integration with existing architecture
• Data loss, security and privacy risks
• Interoperability
• Risk of intellectual property theft
Security
By 2020,the data that requires
protection is growing faster by 40% than
the Digital Universe itself
Networking
Heavy Network Load

22. DATA VISUALIZATION
• Big Data is still so large that it
poses problems, such as dealing
with and attempting to compare a
large percentage of unique values
• Learning new software specially
designed to efficiency deduce
insight
• Learning new machines that
derives knowledge from Big Data.
• New 3D imaging techniques and
immersive telecommunications
may play a part in helping to
visualize Big Data and glean
insights
Visualization has been shown to be an effective tool
not only for presenting essential information in vast
amounts of data but also for driving complex
analysis.

23. CHANGING THE WORLD
While the problems facing computer science and Big Data are paramount,
these issues can lead to opportunities within bioinformatics and health care to
improve the world.
• Improved experiments and advances in data visualization and health
technology are leading to insight into cancer and rare diseases.
• Genomics is helping researchers understand genetic diseases and could
result in profound improvements in treatment.

24. IMPROVING THE WORLD’S HEALTHCARE
Just as the rest of the world is producing large amount of data, improved experiments and
health technology are producing more data that is too complex for traditional data analysis.
CLINICAL ARCHIVING : helps accurate diagnosis unnecessary procedures.
Each year more than 600 million diagnostic images are taken in the U.S. alone. Diagnostic
images are X-Rays, MRIs and CT scans.
PREVENT HOSPITALIZATION :Big Data predicts when you are likely to get sick; track
patients and advise you so as not to get so sick.
PREDICTING OUTBREAK :Early identification contain its spread and allocate resources
more effectively

25. CHALLENGES OF UNIQUE HEALTHCARE
HUMAN ERROR: Large fraction of critical data still rely heavily on human entry who
unintentionally and intentionally introduce systematic errors
DATA FRAGMENTATION: Incomplete data are common in clinical practice. Incomplete data,
like inaccurate data can be harmful to patient care
