Can a thread create a process?
No, a thread can't create aprocess, because the environment of the thread is a part of a process which created this thread.
What resources are used when a thread is created?
When a thread is created the threads does not require any new resources to execute the thread shares the resources like memory of the process to which they belong to. The benefit of code sharing is that it allows an application to have several different threads of activity all within the same address space. Whereas if a new process creation is very heavyweight because it always requires new address space to be created and even if they share the memory then the inter process communication is expensive when compared to the communication between the threads
Can a thread be called a process or vise versa?
No. A thread is a part of a process, but a process can not be part of a thread. Processes are always "at the top."
What is the difference between a process and thread?
The same metaphor: the difference of a person (thread) and a family (process) A process has at least 1 thread and may have many threads, while 1 thread must live within a process
What is a thread in computers?
Execution context within a process is called Thread. Threads run, process does not. Every process starts with one thread.
What of these components are shared by a multithreaded process?
There r some resources shared by different threads o the same process while some r not. The threads shares the address space,file,global variables. But each threads has its own stack , copy of registers(including PC).
What is the difference between lightweight and heavy weight process?
Light weight is called as a thread which runs inside a process and a heavy weight is a system process. As the thread share the memory of heavy weight then we can say that it is not taking any additional resources(memory) to execute. As a process is a combination of one of more then one threads and each process is having the separate memory location so it is very easy for thread to communicate with each other as compare to two process communicate because thread communicate within same memory but process communicate with other process having different memory location. Here we can consider light weight as a thread and heavy weight as a process.
When was By a Thread created?
By a Thread was created in 2009-01.
If a process terminates will its thread also terminate?
yes, because if process is terminated then its related thread has no work. After completion of process the kernel generates a thread that will cancelled the thread in order to save the time and memory of CPU.
What is a thread in c?
A thread is basically a lightweight process.
What is difference between child process and thread?
The child process is initially running its parent' s program, with its parent' s virtual memory, file descriptors, and so on copied.The child process can modify its memory, close file descriptors, and the like without affecting its parent, and vice versa. When a program creates another thread, though, nothing is copied.The creating and the created thread share the same memory space, file descriptors, and other system resources as the original. If one thread changes the value of a variable, for instance, the other thread subsequently will see the modified value. Similarly, if one thread closes a file descriptor, other threads may not read from or write to that file descriptor.
