The document discusses several key concepts in advanced computing techniques including networks, computing, pervasive computing, mobile computing, cloud computing, and big data. Networks allow nodes to share resources by exchanging data through connections established via cable or wireless media. Cloud computing provides on-demand access to configurable computing resources like servers, storage, databases, and applications via the internet. Big data involves extremely large data sets that are difficult to process using traditional data management tools due to their size, diversity and complexity.

What is Ubiquitous Computing?
Ubiquitous computing (alias: Pervasive Computing) is a paradigm in which the processing of information is linked with each activity or object as encountered. It involves connecting electronic devices, including embedding microprocessors to communicate information. Devices that use ubiquitous computing have constant availability and are completely connected.
Ubiquitous computing focuses on learning by removing the complexity of computing and increases efficiency while using computing for different daily activities.
Ubiquitous computing is also known as pervasive computing, everyware and ambient intelligence.

resources.
In computer networks, exchange data with each other using
a data link.
The connections between nodes are established using
either cable media or wireless media.
Network computer devices that originate, route and terminate
the data are called network nodes.
Nodes can include hosts such as personal
computers, phones, servers as well as networking hardware.

18. OPPORTUNITIES AND
CHALLENGES
The use of the cloud provides a number of
opportunities:
It enables services to be used without any
understanding of their infrastructure.
Cloud computing works using economies of scale:
no longer need to buy their own software or servers.
Cost would be by on-demand pricing.
Vendors and Service providers claim costs by establishing
an ongoing revenue stream.
Data and services are stored remotely but accessible
from “anywhere”.
18
Basic concepts of Advanced Computing Techniques - Mrs.
A.Mullai
19. ADVANTAGES OF CLOUD
COMPUTING
Lower computer costs:
You do not need a high-powered and high-priced
computer to run cloud computing web-based
applications.
desktop PC does not need the processing power or
hard disk space – UNLIKE traditional desktop
software.
PC can be less expensive, with a smaller hard disk,
less memory, more efficient processor...
does not even need a CD or DVD drive, as no
software programs have to be loaded and
no document files need to be saved.
19
Basic concepts of Advanced Computing Techniques - Mrs.
A.Mullai
20. …ADVANTAGES OF CLOUD
COMPUTING
Improved performance:
better performance - PC.
Computers in a cloud computing system boot and run
faster - because they have fewer programs and
processes loaded into memory…
Reduced software costs:
Instead of purchasing expensive software
applications –
can get most of what you need for free
most cloud computing applications today, such as the Google Docs
suite.
better than paying for similar commercial software
which alone may be justification for switching to cloud applications.
20
Basic concepts of Advanced Computing Techniques - Mrs.
A.Mullai
21. …ADVANTAGES OF CLOUD
COMPUTING
Instant software updates:
no longer faced obsolete software and high upgrade costs.
application is web-based, updates happen automatically
available the next time you log into the cloud.
you get the latest version
without needing to pay for or download an upgrade.
Improved document format compatibility.
machine being compatible with other users' applications or
OS.
no format incompatibilities - sharing documents and
applications in the cloud.
21
Basic concepts of Advanced Computing Techniques - Mrs.
A.Mullai
22. …ADVANTAGES OF CLOUD
COMPUTING
Unlimited storage capacity:
Cloud computing offers virtually limitless storage.
Your computer's current 1 Tbyte hard drive is small
compared to the hundreds of Pbytes available in the cloud.
Increased data reliability:
Unlike desktop computing, in which if a hard disk crashes
and destroy all your valuable data, a computer crashing in
the cloud should not affect the storage of your data.
if your personal computer crashes, all your data is still out there in
the cloud, still accessible
In a world where few individual desktop PC users back up
their data on a regular basis, cloud computing is a data-
safe computing platform!
22
Basic concepts of Advanced Computing Techniques - Mrs.
A.Mullai
23. …ADVANTAGES OF CLOUD
COMPUTING
Universal document access:
That is not a problem with cloud computing, because you
do not take your documents with you.
Instead, they stay in the cloud, and you can access them
whenever you have a computer and an Internet connection
Documents are instantly available from wherever you are
Latest version availability:
When you edit a document at home, that edited version is
what you see when you access the document at work.
The cloud always hosts the latest version of your
documents
as long as you are connected, you are not in danger of having an
outdated version
23
Basic concepts of Advanced Computing Techniques - Mrs.
A.Mullai
24. …ADVANTAGES OF CLOUD
COMPUTING
Easier group collaboration:
Sharing documents leads directly to better collaboration.
Many users do this as it is an important advantages of
cloud computing
multiple users can collaborate easily on documents and projects
Device independence.
no longer tethered to a single computer or network.
Changes to computers, applications and documents -
through the cloud.
Move to a portable device - applications and documents
are still available.

29. …BIG DATA
Volume:
it is the size of the data that explains the value
and information & whether it can be viewed as
a big data or not.
Variety:
it determines the class the big data
belongs to
it is also an essential factor that the data
analyst should know.
Velocity:
refers to the speed of production of the

30. …BIG DATA
Variability:
it causes an issue to the people who analyze the
information.
Veracity:
The quality of the information may vary a lot
precision of analysis depends on the veracity factor of
the source information.
Complexity:
The management of the data can become a difficult
process -
huge information comes from different sources.
All these information needs to linked, correlate and
connects with each other
to acquire the data that is supposed to be transferred
by this information.

research and development initiative - it is used to address
many issues faced and also utilized by the Indian
government.
International development:
cost-effective opportunities to enhance the decision in
critical advancement areas like health care, employment
opportunities and crime, security and natural disaster.
Manufacturing:
In manufacturing, the big data furnishes an infrastructure
for transparency in manufacturing or producing industry.
35
Basic concepts of Advanced Computing Techniques - Mrs.
A.Mullai
36. ...APPLICATIONS OF BIG DATA
Cyber-physical models:
The present PHM implementations make avail of data
during the actual usage
analytical step by step procedures can do more
precisely - when more data is included.
Media: I
it is used in the internet of things - the activities like
targeting of computers and data capturing.
Technology:
In the technology, it is used in the websites like eBay,
Amazon and Facebook and Google utilize it.
