Road To 200 OCR A Level Computer Science Resources: 2 Compression Exam Question Docs

As Salamu Alaykum Wa Rahmatullahi Wa Barakatuh World!

This is the first resource or resources should I say on the exchanging data section. Both are to do with compression (both lossy and lossless) and they're both also pretty much different versions of the same resource.

They both address the exam question of explaining both compression techniques. The first answer i.e. the "harder" one, starts off well in terms of being relevant to the OCR spec but then gets a bit complicated and beyond the scope of the spec.

The "easier" one is more basic but gives a more relevant answer to the OCR spec. I guess it's good have both so you get the best of both worlds. Anyway, i'm going to try and find more resources for this topic but it's not easy since most of them are A) not specifc or even relevant to the OCR spec and B) get way too complicated and by default go beyond the scope of the specification.    

Here's the links:

• The harder and a bit unnecessary answer
• The easier yet more relevant answer

Hope this helps!
