- saves time and safer commutes as human error eliminated
What is cloud computing?
delivery of on-demand computing recourses over the internet: from applications to data centres
replaces trad method of locally based server
What are the two main types of cloud setups?
Public cloud-hosted by 3rd party company
Private cloud-IT service provides for own organisation

4Vs Volume Velocity:speed data is fed Variety:formats Veracity:reliability
2 main forms of Big Data?
structured (feedback data) vs unstructured (liked, social media)
Where can you find Big Data?
Human-sourced data e.g social media, emails
Machine-generated data e.g smart tech, sensors
Processed data e.g in databases
Open data e.g publicly available data
What is data analytics?
collecting, organising and analysing big data to discover patterns and other information which could inform decisions
What are the 3 steps to data analytics?
Collection of data:int and ext sources
Organisation of data:organised and stored for future use
Analysis of data:find correlations/patterns
What has McKinsey stated are the benefits of effective data analytics?
Fresh insight and understanding Performance improvement Market segmentation and customisation Decision making Innovation Risk management
What is process automation?
technology enabled automation of complex business processes aimed at improving consistency, quality and speed whilst delivering cost savings
How is traditional process automation different from modern process automation?
simple repetitive task replaced to automation of complex business problems
automation is becoming smarter and can make decisions using reasoning language and learned behaviour

- voice recognition and AI
- calls answered robotically
- data capture and analytics used to monitor calls
- led to cost savings and service improvements
What is Artificial Intelligence? What is the Kaplan definition?
area of computer science that emphasises the creation of intelligent machines that work and react like human beings
Kaplan definition: system’s ability to correctly interpret external data, to learn from such data ad to use those learnings to achieve specific goals and tasks through flexible adaptation
What are some examples of advanced activities AI can now master?
voice recognition
planning
learning
problem solving
AI in business?
Apple and Amazon use voice recognition in existing products or developing products
Facebook uses AI to recommend friends
What is machine learning?
- subset of AI
- code mimics human thoughts
- uses data to calculate probability and learn from mistakes
- detects patterns to make predictions and recommendations
AI use in the game GO
- more advanced version of chess
- Google DeepMind played against world champion in 2016
- -Move 37 appeared bad but turned out to be game winning move
- computer built knowledge from previous games
- Lee Sedol found AI limitations to beat computer
What is data visualisation?
allows large volumes of complex data to be presented in a visually appealing and accessible way that facilitates understanding and use of underlying data
What is the most common use of data visualisation?
creating a dashboard to display the key performance indicators of a business in a live format
What 5 features should an effective data visualisation tool display?
decision making ability-results focused effective infrastructure-output reliant on quantity/quality of data integration capability prompt discovery of rules and insight real time collaboration
What is blockchain?
decentralised, distributed and public digital ledger used to record transactions across many computers
cannot be altered retroactively without all blocks being changes and consensus of network
BOE:allows people who do not know eachother to trust a shared record of events
Benefits of blockchain?
security from cyber crime
What are the key features of blockchain?
- number of participants record transactions via internet on publicly available ledger
- details recorded by everyone
- verification carried out by computers in decentralised network and discrepancies rejected
- new block added is linked to previous block using cryptographic hash which ensures chain is never broken and always recorded
What are the 6 stages of a blockchain transation?
- A transaction is requested
- A block is created as a digital representation of the transaction
- The block is sent to every node in the network (distributed ledger)
- The nodes validate the authenticity of the transaction
- The nodes receive a reward for the proof of work i.e some Bitcoin
- The completed authorised block is added to the chain
Describe the characteristics of cryptocurrency
Bitcoin (2009, Ethereum and Litecoin)
- no physical version
- peer-to-peer payment network made up of users’ accounts
- can acquire by exchanging money for bitcoin (most common) or bitcoin mining (solving problems generated by Bitcoin network)
- stored in encrypted wallet using password protection
- no need for central bank
- no pre-reqs or transaction limits
