What does it mean to have multiple threads in a process?

What does it mean to have multiple threads in a process?

Multiple threads within a process share the same data space with the main thread and can therefore share information or communicate with each other more easily than if they were separate processes. Threads sometimes called light-weight processes and they do not require much memory overhead; they are cheaper than processes.

How does each thread have its own heap?

Each thread has its own stack and call stack. Each thread shares the same heap. It depends on what exactly you mean when saying “heap”. All threads share the address space, so heap-allocated objects are accessible from all threads.

Where does a thread library need to be implemented?

Thread libraries may be implemented either in user space or in kernel space. The former involves API functions implemented solely within user space, with no kernel support. The latter involves system calls, and requires a kernel with thread library support. There are three main thread libraries in use today:

How can thread go from waiting to Runnable state?

If the target thread holds a lock on object when it is suspended, no thread can lock this object until the target thread is resumed. c.

What are the different types of meter threads?

Meter Connection Types. AWWA Meter Threads (male) – 1/2″ – 2″ meters. AWWA Meter threads are referred to by the size of the meter connection, not the actual measurement. Meter threads are straight threads, unlike pipe thread which is tapered.
