7.2 Areas of emerging technology and innovative applications within a commercial and domestic context
Reflection Techniques
Kolbs Experimental cycle
1- Concrete- Having an experience. Creates an opportunity for learning.
2- Reflective observation
Reviewing on the experience. Change from seeing and doing to reflection can increase the understanding of the experience.
3- Abstract conceptualization
Learning from the experience. Problems and issues can be identified.
4- Active experimentation- Concluding/Learning from the experience. Will learn from the practical application of ideas and consider how they are going to put what they learnt into practice.
Boud, Keogh and Walker's model
Experience- You consider the behavior, ideas and feelings that occurred. Starting process of the reflective process.
Reflective- The negative feelings and behaviors you identified are removed, with the focus being on the positives that occurred. You can then re-evaluate in a positive way.
Outcomes- Expands on the positive reflection and perspective of the experience. you have gained new experiences and perspectives, so you can commit to the changes that need to be made.
Gibbs' reflective cycle
Description- This stage is about what happened, conclusions come later in the cycle. The task, the situation or project needs to be fully described without making any judgements or coming to a conclusion.
Feelings
The focus is on the feelings and reactions that occurred during the situation, task or project. A description of the reactions and feelings is needed.
Evaluation- Evaluating the positive and negative actions and outcomes. What was good and bad about the experience.
Analysis- Attempts to explain why the experience was positive or negative and should form the largest section of the reflection .Why did things go well or badly? How did you contribute to the success or failure of this experience?
Conclusion- The actions and outcomes from a situation, tasks or project should be summarised. The conclusion should be based on the response to the previous stages and focus on what has been learned.
Action Plan- Formulate an action plan recording future plans and areas for improvement. The plan should include anything that needs to be known and done to improve for next time.
Blockchains
A Software Protocol that allows the secure recording of data and information.
They are a combination of different technologies, database, software application and an internet connected digital device.
Structure
The first block is known as the Genesis block
Each block in the chain is linked to the previous block going back to the Genesis block.
Each block contains data/ information hash of previous block.
Each block contains a unique hash that identifies the block and the data/ information it contains.
All blocks contain the hash of the previous block in the chain, it's this that makes it so secure.
Common types of Block Chains
Public
These are large distributed networks that operate using a native token (e.g. Bit coin). A public blockchain
usually has open source code that there community maintains.
Permissioned
This is a blockchain network that is only accessed by selected uses. They also use a native token like Bitcoin. An
example is Ripple that uses XRP tokens (their own currency).
Private

They are used by private
consortiums who have very trusted members who trade confidential information (examples: Financial Services,
Healthcare, Government Services, Retail, Insurance, Real Estate, and Supply Chain).
5G
Was designed to improve download speed and reduce latency
5G cells expand mobile networks by boosting capacity as users need it. E.G at a festival or stadium.
They extend coverage by using indoor cells that use the internet connections to ensure people always have a signal.

Up to 10Gbps data rate - > 10 to 100x speed improvement over 4G and 4.5G networks.
1-millisecond latency.
1000x bandwidth per unit area.
Up to 100x number of connected devices per unit area (compared with 4G LTE)
99.999% availability.
100% coverage.
