Google is your friend.
There's also the local library.

If everything was on Google - there would be no need for questions
here.

Everything _is_ on Google :-)
This just goes to show that formulating the right question is a
greater art than finding the answer :-)
And to the poster:
No, there is no real reason why they choose 7 for the number of
layers. It took them 7 years to get there. That's the closest to
an answer I have ever seen. They could have choosen almost any
number.
The forte of OSI is, that they showed the networking community
that it is smart to slice the problem. And that it works best if
everyone agrees on the boundries between the different functions.
