Activities beside the
story
1) Discuss how Big Data is increasing in volume,
variation, velocity, veracity and value.
Ans:- When we like a
post on Facebook or share a post on WhatsApp, visit any website, make online
purchases, or watch videos, the variety of activity we do online is recorded,
monitored and analysed. So a huge amount of data is collected. Data is also
collected swiftly from different sources, for example web, sales, customer
contact centre, social media, mobile data and so on. Big Data analytics is used
to give insights that were previously incomprehensible. As more and more people
use the Internet, social media, make online purchases, use mobile phones, and
are generally more active online, Big data is increasing in volume, variation,
velocity, veracity and value in leaps and bounds.
Ans:- When we order something online, we are given a
tracking number. By logging into the website of the company and entering this
tracking number in the given slot, we can find out the location and condition
of the goods.
3) How can you reduce risk in transport?
Ans:- Big Data has been
useful in identifying and tracking the exact location of a place. GPS and
Google Maps make use of Big Data. With geographic positioning and radio
frequency identification sensors we get the up-to-date data about traffic, congestion
on a particular route, information if the route is closed or if it is a one-way
route, understanding accident prone areas, etc. Thus, we can plan our own route
according to the travel time and the transportation of goods. If we have
ordered something online, we can track the location of our goods in transit, we
can also track the condition of the goods. All this has immensely helped the
logistics companies to reduce risks in transport, improve speed and reliability
in delivery.
4) Do you think Big Data has improved the quality of
life? How?
Ans:- Big Data has
certainly improved the quality of life. Through various apps, we can maintain
our body weight and exercise levels, and remain healthy. Our heart rate, sleep
patterns, etc. can be monitored and any changes can be immediately reported to
the doctor, who can then prescribe the correct treatment as soon as possible.
Age-related diseases like diabetes and arteriosclerosis can be treated at the
early stages. Thus, we can lead healthier and more active lives. Big Data is
also being used to predict and monitor epidemics, thus ensuring that they
affect as few people as possible.
5) Can we understand the economy of the country by the data on Banking and
Finance?
Ans:- Yes, we can. With
the Big Data analytics the study of investment patterns of the people can be
done. We can analyse the bank deposits made, the loans taken and the equity
trading. We can find out the business across borders. We can find out how many
industries have come up, and what the industrial economy is. From all this
information, we understand the economy of the country.
6) Do you think people click consciously on Facebook? Discuss.
Ans:- Points - in
general, most people just press ‘like’ button on friends’ posts, many times not
even reading the post - sometimes some
only repeat the comment above theirs – some forwards and videos are not even
seen - with so many posts and information many times there is no time to read
everything.
7) Do you think Big Data will help to bring improvement
in students?
Ans:- Yes, Big Data
will certainly help to bring improvements in students. Students can learn
topics/subjects according to their abilities and capacity. They can choose
their careers after knowing their strengths and weaknesses, their mental
make-up and abilities. Thus, there will be fewer drop-outs, and students will
be happy in the careers they have chosen.
Ans:- Through Big Data we have information about the
study patterns of students, and we can now prepare customized and dynamic
learning programmes according to the need of an individual student.
BRAINSTORMING
(A1) Youtube has many videos on various things. Listen to the uses and
health benefits of 'Lemon' and share them with your friends.
Ans:- Lemon is a rich
source of vitamin C which helps to cure common cough and cold. Lemon is a
citrus fruit which is very useful to get rid of acidity if its juice is
squeezed and consumed regularly in the morning, before breakfast, mixing it
with lukewarm water. Research has proved that a lemon or any citrus fruit rich
in vitamin C reduces the risk of heart-related diseases. Lemon peels are also
beneficial as they contain calcium, potassium and of course, vitamin C. Lemon
peel is good for oral hygiene, skin care, weight loss and most importantly to
increase immunity. So, lemon is not only a healthy fruit, it has got a distinct
smell and pleasant taste to enhance the quality of the food.
