What data do the threads of the same process share?

Question

System administration

The teacher gave us questions for the test. And one of them is this question. I don't even know how to understand it, let alone answer it. Googled, didn't find an answer. Help me please.

Answer 1

Kek, he asked the same question today at the test. But time doesn't add up.
General:
- Address space
- - As a result, executable code
- - As a result, environment variables
- Open descriptors
Differs:
- Stack: each thread has its own, in one address space. but in its different places
- Structural exception handlers
- Well, in general, the context of the thread: processor registers, etc.
