Question
Which of the following is/are shared by all the threads in a process?I. Program counter
II. Stack
III. Address space
IV. Registers
II. Stack
III. Address space
IV. Registers
Correct answer
(B) III only
Solution
In a multithreaded process, threads share the process's resources, including its Address space (which contains the code, data, and heap segments) and operating system resources like open files and signals. However, each thread must maintain its own execution state to run independently. This private state includes its own Program counter, Stack, and Registers. Therefore, only (Address space) is shared among all threads.
