Question 2

What are some sources of BIG data?

Answer 2

• Remote sensing: Radiation from target area
• In situ: Measurements made on the actual location of object
• Simulation data/datasets: Output of Earth models, e.g. climate
• Social media data: Trends/Preferences
• Infrastructure data

Question 3

What is the analysis method of Data Pre-Processing?

Answer 3

From existing data, remove noise, correct data and reduce data size

Question 4

What is the analysis method of Statistical Analysis?

Answer 4

Mathematical method. Receive historical data from data mining and transform that into knowledge to predict relevant phenomena.
Regression analysis, Clustering, Deep learning

Question 5

What is the analysis method of NON-statistical Analysis?

Answer 5

Linked data: Structured data where datasets are interlinked. Data is sharable and relationships among data are recorded

Question 6

What are 4 Cloud computing applications for BIG DATA?

Answer 6

• Cloud storager for BIG DATA storage
• Cloud Computing for BIG DATA Processing
• Cloud Computing for BIG DATA Analysis
• Cloud Computing for BIG DATA sharing and remote collaboration

Question 7

What a characteristic of Edge computing?

Answer 7

Fast processing and app response time
Low jitter
Location aware and supports mobility
Distributed, shorter path to server minimizes en-route attacks
LESS SCALABLE

Question 8

What is “ a subset of edge computing. Focuses on network infrastructure”?

Answer 8

FOG

Question 9

What are some characteristics of FOG?

Answer 9

Hierarchal, it extends clouds capabilities to edge

Question 10

How does FOG enable local processing?

Answer 10

It introduces intermediate computing nodes between edge devices and centralized cloud servers

Question 11

Where is FOG often applied?

Answer 11

Where network intrastructure plays a big role:
- Smart cities
- Industrial automation

Question 12

What is Mobile Edge Computing (MEC)

Answer 12

Focuses on brining computing resources and capabilities to edge of mobile networks

Deployed near base stations or cell towers which leads to
- Low latency processing
- Improved performance
for mobile networks

Question 13

Explain Cloudlet

Answer 13

Small-scale locally hosted data centre located at edge of network

Serves as intermediate tier between mobile devices and traditional centralized cloud servers
