What's the difference between Intel Edison and Galileo?

Question

Arduino

I want to touch the iron component of IoT, but I don’t know where to start.
All these Edison and Galilee arduinos are misleading.
There are also kits (Kit) I would like not to screw up when buying.
What to buy and what not?
Edison is sort of like a processor (SoC), and for him there is also a "motherboard" where it is inserted,
but Edison is on an atom, but I would like to start with a quark, since it seems to be the smallest.
Where did this "SD card" go?

Answer 1

I answer myself.
Good articles on Habré with descriptions of products, everything becomes clear from the description.
Galileo
Edison

Answer 2

What to buy? This issue is easily solved!
1. Decide what you need it for.
2. Go to the website of board manufacturers and read-read-read.
3. Fill in the table of correspondence of the board to your requirements.
4. Choose the board that suits you the most.
Knowing full well that it will take a lot of letters to read, and this is not held in high esteem now, I will tell you about the second way:
Buy Galileo.
