what are these components called, the boards inside the board

Hi Sergei, welcome to the Community. What is it you are trying to do exactly? What do you need assistance with? In a board you have:

• cards - they represent issues
• swimlanes - horizontal rows that allow you to organize the presentation of issue
• columns - that represent statuses in your workflow

all of this is configured under Board settings if this is a Classic project.
