Reflection is important
If we did well, then why? Can we repeat what we did for future exams across subjects?
If we didn't do well, what CAN we do to overcome these challenges next time
Channels
Being on the same channel as too many other devices in the same area leads to interference - this slows down the rate at which data can be transferred
Wi-Fi
Selecting a 'quieter' channel would help to resolve this
WAP's transmit data on certain frequencies (2.4 and 5 GHz)
Task
A frequency is the rate at which the signal changes per second (measured in GHz)
A channel is the range on that frequency at which the WAP operates on e.g. 2.412 GHz

- Highlight YOUR areas of misconception/weakness
- Use google classroom and complete activities to help 'plug' the gaps in your knowledge
