- Also more internal controls are needed when dealing with people private data
5
Q
What are the changes to accounts following new technology introduction
A
- Simple tasks can out outsourced to other countries or to AI
o Focus now on telling the story to not the completion of the process - Accountants have to become more IT skill based
6

10
Q
What is big data
A
- The mass of data society creates in this ever connected world
- Involves the collection and analysis or large amounts of data to find trends, understand consumer needs and help organisations focus resources more efficiently
- Can be both structured and unstructured from all different sources
11
Q
What are the 10 V’s of big data
A
- Volume
- Velocity
- Value
- Veracity
- Variety
- Vulnerability
- Volatility
- Visualisation
- Validity
- Variability
Only need to focus on 1, 2, 4, 5
12
Q
What is volume of big data
A
Online lives produces terabytes of data and need to work out which is useful and adds value and what does not
13
Q
What is velocity of big data
A
- The data is generated quickly and need to be able to collect and process it in real time
- Being late is missing opportunities
o E-promotions based on location
o Healthcare data
14
Q
What is veracity of big data
A
- The level of confidence or trust in the big data
- How accurate is it
- Key questions:
o Who created the data
o What methodology what followed collecting it
o What was the scope (all customers covered)
o How has it been summarised
o Has it been edited or modified
15
Q
What is variety of big data
A
- How complex is the data
- Structured or unstructured
- Is it in a table, free text, graph
16
Q
What is data at rest
A
- Data that is housed physically on computer storage
- Corporate files, backup data storage
- Links to volume
17
Q
What is data in motion
A
- Data en route between source and destination
- Can be streaming data that requires millisecond responses
- Links to velocity
18
Q
What is data in many forms
A
- This is the different structures data can take
o If it is in graphs, free text, excel - Links to variety
19
Q
What is data in doubt
A
- When there is uncertainty due to data inconsistencies, incompleteness, ambiguity, latency, deception or model assumptions
- Links to veracity
20
Q
What are the problems with big data
A
- Data needs to be secured
o Both physically and online - Respecting privacy
- Costs of managing all this and potential fines of getting it wrong
o Need to do cost benefit analysis
21
Q
What are the characteristics of useful information in accounting
A
Reliable
* Free from error or bias, accurately represents organisation, events or activities
Complete
* Does not omit important aspects of events or activities it measures
Timely
* Provided in time for decision making to occur
Understandable
* Presented in a useful and intelligible form
Accessible
* Available to users when they need it in the form they can use it
22
Q
What are information systems
A
- An information system is a collection of computer hardware and software that can provides decision-making, control or other similar information based on underlying data, as well as capture and process organisational data
- Encompasses the technology in the organisation and the people who use it
23
Q
What is hardware
A
- When referring to information technology, the term hardware means the physical computing machinery and equipment used to capture, process and store data.
- E.g Keyboard, touchscreen, mouse, bar-code reader, microphone, pointing devices, scanners
24
Q
What is software
A
- Operating System Software performs a computer’s basic functions, such as:
- Application management, Input/Output management , Device management, Memory management, Processor management, Hardware management
25
What are networks
* Communications hardware provides links between computers.
* A collection of computers and/or other hardware devices which are linked together.
* Key element of any computer network is a protocol – a set of rules governing communications across the network.
* The most common protocol for local networks is the Ethernet protocol, while TCP/IP (short for Transmission Control Protocol/Internet Protocol) is the most common protocol used on larger networks like the internet.
* Local Area Network (LAN) – a network which is geographically close. A typical office network within one or several adjacent buildings is a typical example of a LAN.
* Wide Area Network (WAN) – a network over a larger geographical area
26
What is data protection
* An organisation must obtain and process data fairly
* Data must be obtained for one or more specified and lawful purposes
* Data must be processed in ways compatible with the purposes for which it was obtained
* Data must be kept safe, secure, accurate and up-to date
* Any data obtained must be adequate, relevant and not excessive
* Data should not be retained for longer than necessary
* Should any individual request information on data held on them, this information must be give
27
What is business continuity planning
* Business continuity planning (or disaster recovery planning) refers to policies and procedures to reinstate normal business in the event of business disruption
* Business continuity planning focuses on how the company can restore business operations after a disaster strikes.
* Level of BCP for information systems depends on the type of business
* Easy to think of the effects of a natural disaster, but what about having no information systems, or restricted information systems?
* First line of defence of a typically good IT management practice
o Daily backups of key data (consider location of backup medium) – online backup solutions?
o Redundant hardware
* A purchased BCP solution – typical and good practice for larger organisations, essential for online business
* Assess the solution cost versus cost of having no information system (e.g. lost revenue)
28
What is financial accounting
Financial accounting provides information to external users, typically in the form of summarised financial reports such as the income statement and statement of financial position. The information is based on historical data; a highly regulated branch of accounting.
29
What is management accounting
Management accounting is concerned with the provision of information to managers to help them make business decisions; management accounting aims to provide more detailed and timely information to internal users of accounting information
30
What are the limitations of spreadsheets
* Might not be able to fulfil the requirements of the business of a certain size
* Physically limited in rows and columns
* Difficulties integrating data into the spreadsheet
* Limitations of user skills as it is a blank template
