What is not shared between threads?
Threads share data and code while processes do not. The stack is not shared for both. Processes can also share memory, more precisely code, for example after a Fork() , but this is an implementation detail and (operating system) optimization.Click to see full answer.

Threads share data and code while processes do not. The stack is not shared for both. Processes can also share memory, more precisely code, for example after a Fork() , but this is an implementation detail and (operating system) optimization.Click to see full answer. Keeping this in view, what is shared between threads in the same process?In a multi-threaded process, all of the process’ threads share the same memory and open files. Within the shared memory, each thread gets its own stack. Each thread has its own instruction pointer and registers.Secondly, what resources do Threads share? Threads are not independent of one another like processes are, and as a result threads share with other threads their code section, data section, and OS resources (like open files and signals). But, like process, a thread has its own program counter (PC), register set, and stack space. In this regard, do Threads share the same heap? It is important to distinguish between these two types of process memory because each thread will have its own stack, but all the threads in a process will share the heap. Threads are sometimes called lightweight processes because they have their own stack but can access shared data.Do threads share registers?In general each thread has its own registers (including its own program counter), its own stack pointer, and its own stack. Everything else is shared between the threads sharing a process.
