Data Representation Revision

Data Representation Revision I will number you from 1 – 7. On the following slide are 7 topics – remember the one corresponding to your number.

Data Representation Revision Binary to Denary and Denary to Binary Binary Addition Binary Subtraction Binary to Hexadecimal and Hexadecimal to Binary Hexadecimal to Denary and Denary to Hexadecimal ASCII, Images and Pixels Sound

Revision Task Create an interactive lesson on PowerPoint on your topic. Learning: The topic should be broken into small chunks of learning e.g. 1 slide to explain what binary & denary means, another to explain how to convert You may want to include worked examples Testing (you should test the user’s knowledge) Display a message if the user gets it right or wrong If the user gets it wrong you should have an explanation showing them how to work out the right answer or…you could give them a hint instead of the right answer.
