2.1. Dạng 1: Big Data 

Câu 1:

A.  Volume 
B.  Visibility 
C.  Verification 
D.  Variability 
E.  Velocity 
F.  Variety

Câu 2: 

Learning outcome: Acknowledge the sources and uses of big data 

Question: Are the following statements true or false?

Big data analytics allows businesses to analyse and reveal insights in data that they have previously been able to analyse. 

TRUE 

FALSE

In order for organisations to analyse big data and to gain insights from it, the source data needs to be structured within a software package. 

TRUE 

FALSE

One of the key features of big data is the speed with which data flows into an organisation, and with which it is processed. 

TRUE 

FALSE

Answer:  

Big data analytics allows businesses to analyse and reveal insights in data that they have previously been able to analyse. 

TRUE

 

In order for organisations to analyse big data and to gain insights from it, the source data needs to be structured within a software package. 

 

FALSE

One of the key features of big data is the speed with which data flows into an organisation, and with which it is processed. 

TRUE

 

Big data is collected from diverse sources and much of the resulting data is unstructured; for example, one significant source of big data can be the opinions and preferences that people express via social media. So, the second statement is incorrect.  

Big data analytics is a recent development and enhances an organisation's ability to analyse  and reveal insights in data that had previously been too difficult or costly to analyse – due to the volume and variability of the data involved. The first statement correctly identifies this point.  

One of the key features of big data is the speed with which data flows into an organisation  (with much data being available in real-time, or almost in real-time). If an organisation can then also process this data quickly, this can improve its ability to respond effectively to customer requirements or market conditions. The third statement identifies this point. 

2.2. Dạng 2: Information systems 

Câu 3:  

Question: Which TWO of the following are benefits of wireless technology? 

A.  Better decision making 
B.  Increased productivity 
C.  Increased security 
D.  Reduced costs as businesses expand

Answer: B, D 

Increased productivity occurs because employees can work together wherever they need to.  Costs are reduced as the business expands because it is easier to add new users to a wireless network than to install new cabling. 

If using wireless technology in public places, it may not always be possible to find secure networks therefore security can be an issue. Wireless technology will not necessarily lead to better decision-making. 

Câu 2: 

Question: The following statements have been made about information systems. 

1) Feedback is information produced from a system that is used by management to take action to control further inputs to the system. 

2) Information for benchmarking purposes may be obtained from both internal and external sources. 

Which of the above statements is/are true? 

A.  1 only 
B.  2 only 
C.  Neither 1 nor 2 
D.  Both 1 and 2 

Answer:

Feedback is information produced by a system as control information for management.  Benchmarking means comparing the performance of an organisation, or part of an organisation, with a 'benchmark'. The benchmark may be an external organisation, such as a competitor company,  or another department or division within the same organisation.
