The OP received answers to absolutely all of his questions in several variations. This is becoming regular. The beginner creates a bunch of questions, the answers to which in the section for beginners are written through the topic. And we don't see these newcomers anymore. Created a topic, received no merit, left to register another account.
How many answers were received, and the OP did not appear to answer whether he understood everything, or he still needs to repeat the same thing ten times.
Please note that people who come here for knowledge are not worried about making money and do not create such topics. And, unfortunately, there are very few of them.
