Which of the following is true about a thread in the operating system...
Threads are lightweight as they can interact without the need of inter-process communication. Switching between kernel threads of the same process requires a small context switch. Only the values of registers. Program counter and stack pointer are changed whereas memory management information doesn’t need to be changed since the threads share an address space. That is switching between threads is cheaper than switching between processes.
