ALOHA, CSMA : improvement suggestion

[GTihon]

I think it should be said more explicitly that CSMA and ALOHA are protocols of the Datalink layer (the words "datalink layer" appear only twice in the entire section of "sharing ressources").
It's only when I read the end of the syllabus that I was able to say that it is a protocol of the datalink layer... but perhaps I'm wrong in fact. Anyway, I think it would be better to say which layer this protocol belongs to.
