What does the internal structure of a coroutine's execution context consist of?

The scope of coroutine execution (for example, in Kotlin) includes several key components:

• Coroutine Context — contains information about the dispatcher, identifier, and lifecycle management elements.
• Dispatcher — determines on which thread or thread pool the coroutine will run (e.g., Main, IO, Default).
• Coroutine State — stores the current execution state, including the suspension point and local variables.
• Job — an object that manages the coroutine's lifecycle and allows it to be canceled.

Internally, a coroutine is implemented as a finite state machine with preserved state, which allows it to suspend execution and resume later without blocking the thread.
