Do threads share kernel stack? Not just each process – each thread has its own kernel stack (and, in fact, its own user stack as well). Remember the only difference between processes and threads (to Linux) is the fact that multiple threads can share an address space (forming a process).
Do threads share a stack? Note: stack and registers can’t be shared among the threads. Each thread has its own stack and registers.
Do threads get their own stack? Within the shared memory, each thread gets its own stack. Each thread has its own instruction pointer and registers. Since the memory is shared, it is important to note that there is no memory protection among the threads in a process.
How Linux is managed? Linux® is an open source operating system (OS). An operating system is the software that directly manages a system’s hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work.
