9th Day of Christmas–Data Representation–Videos for Computer Science OCR 1-9

I like to help out computer science teachers and students. My students have finished studying Data Representation and as a revision tool, I have recorded all of my lessons into lessons under 15 minutes. It’s got some of the tips from my lesson and it also includes step by step guides on how to convert from Denary into Binary. There are videos which explain hexadecimal and there are also some videos which explain how ASCII and characters work. The videos attached should help your students for revision and should help them prepare for the computing exam in 2017.

The video on sound and binary shifts are important things to think about. If you currently have students in year 10 this is high priority on the exam paper. They usually get students to really break down how the sample rate has impact on the size of the file. I’m going to break this down and explain this in as much detail for you in the 4th video.
