Referring back to Block 1 Part 1, state why emoticons might be used in online messages. How can they be used to help avoid causing offence?
Emoticons can be used in place of inflection in spoken words. This allows written text to convey the emotion with the text, and removes a degree of ambiguity that comes with text.
Based on what you have learned about the limitations of mobile computing devices, why might it be important to reduce the amount of processing that must be done by the receiving device used for location sensing?
The power drain of ICT resource intensive activities limits the useful lifetime of the device. So a low-power use is preferable.
At what rate does the strength of a radio signal decrease as the distance from the transmitter increases? What is the name given to this relationship?
As you double the distance from the transmitter, the signal strength reduces by 4 times, this is called the inverse square law.
