How do threads work in OS?

A thread is a flow of execution through the process code, with its own program counter that keeps track of which instruction to execute next, system registers which hold its current working variables, and a stack which contains the execution history. Each thread represents a separate flow of control.

Can threads run on different processors?

A question you might ask is whether processes or threads can run at the same time. The answer is: It depends. On a system with multiple processors or CPU cores (as is common with modern processors), multiple processes or threads can be executed in parallel.

What is thread and multithreading in OS?

A thread is a path which is followed during a program’s execution. These tasks cannot be executed by the program at the same time. This problem can be solved through multitasking so that two or more tasks can be executed simultaneously. Multitasking is of two types: Processor based and thread based.

What are the types of threads in OS?

There are two types of threads to be managed in a modern system: User threads and kernel threads. User threads are supported above the kernel, without kernel support. These are the threads that application programmers would put into their programs. Kernel threads are supported within the kernel of the OS itself.

How process is different from thread?

A process is a program under execution i.e an active program. A thread is a lightweight process that can be managed independently by a scheduler. Processes require more time for context switching as they are more heavy. Threads require less time for context switching as they are lighter than processes.

What do threads share with each other?

Threads are not independent of one another like processes are, and as a result threads share with other threads their code section, data section, and OS resources (like open files and signals). But, like process, a thread has its own program counter (PC), register set, and stack space.

Which of the following does a thread not share with other threads?

Resource sharing: Resources like code, data, and files can be shared among all threads within a process. Note: stack and registers can’t be shared among the threads. Each thread has its own stack and registers.

How do I know what type of thread I have?

Measure the thread diameter. Measure the thread diameter using a caliper to determine the diameter and measure on the thread tops. For tapered thread: measure on the 4th or 5th full thread. For straight thread: measure on any full thread corridor.

Can two threads read the same variable?

Even though the variable is not currently being written to, previous writes to the variable may not yet be visible to all threads. This means two threads can read the same value and get different results creating a race condition.
