I have taken CCNA 1&2 and know a few things, but they changed a lot of the course material, and I don't know any Italian.

For the OSI Layers, the best approach would be to create a sort of memory aid. In my class, we made a phrase where each word shared a common first letter with the layer.

For example, my personal phrase was:
which relates to the layers from first to last:
TCP/IP is only 4 layers, but I didn't focus on it a lot when I took the course.

Data encapsulation is more difficult, and I can't think of any ways to memorize it other than studying a chart, but if you remember the order that the data is converted, then it is much easier to remember which layers each data type is in.
