Computing Science Inside... Zipping it Up

“Zipping it Up”

Number of pupils:
Age range:
Activity type:

Topic:

This workshop questions why it has taken so long to introduce 3G mobile phones, identifying lack of bandwidth as a key issue. It explores the area of data compression and decompression - essential in any application where the bandwidth is low or storage is limited - and gets pupils working with the kinds of algorithms that underlie the Zip utility found on a PC.

Feedback from Teacher to CSinside...(via Feedback Questionnaire)

Extract from Feedback: We ran the workshop with S1 and S3 pupils. This workshop is too difficult for S1 and that is reflected in the comments they made. ....
We added colour to the other worksheets (2 and 3) to highlight the repeating patterns (and ask the pupils to use colouring pencils on the worksheets to underline patterns).

Our network has a block on zip files - great isn't it.
