No, threads do not share memory. Each thread in a program has its own stack memory for storing local variables and function calls. However, threads within the same process can share memory through shared data structures or variables.

What do threads share in a multi-threaded programming environment?

In a multi-threaded programming environment, threads share the same memory space and resources of the program, allowing them to run concurrently and interact with each other.


Do threads share the heap in a multi-threaded environment?

In a multi-threaded environment, threads can share the heap, which is a common area of memory where dynamic memory allocation occurs. This allows threads to access and manipulate shared data stored in the heap. However, it is important to implement proper synchronization mechanisms to prevent data corruption and ensure thread safety.


Do threads share global variables?

No, threads do not share global variables by default. Each thread has its own copy of global variables, which means changes made to global variables in one thread do not affect the values in other threads.


List reasons why a Mode switch between threads may be cheaper than a Mode switch between processes?

Answer# 11. reason - the control blocks for processes are larger than for threads (hold more state information), so the amount of information to move during the thread switching is less than for process context switching 2. reason - the major reason is that the memory management is much simpler for threads than for processes. Threads share their memory so during mode switching, memory information does not have to be exchanged/changed, pages and page tables do not have to be switched, etc. This makes the thread context switch much cheaper than for processes. In case of processes the memory pieces (pages) need to be exchanged, etc. (Will talk about the details in few weeks). 3. reason - threads do not have to worry about accounting, etc, so do not have to fill out all the information about accounting and other process specific information in their thread control block, so keeping the thread control block consistent is much faster 4. reason - threads share files, so when mode switch happens in threads, these information stay the same and threads do not have to worry about it (similar to accounting information) and that makes the mode switch much faster.answer 2## Process :Generally heavy weight by, the PCB holds kernel objects the values generally referred as state information. A application can be divided into two types in design phase: 1.Process - may affect application/program architecture 2.Threads - didn't affect architecture Threads typically are spawned for a short-term benefit where as process for long-term even the thread share its own process address space is never larger than 4GB. A single process may hold "n" threads so exchanging value between process; then the CPU spend most of its time for swapping it leads to thrasing definitely. Threads easily exchange their locale variables within its scope but exchange value between process stolen more CPU cycles.

What are the different things shared by different threads of a single process?

Threads of a single process share the same memory space, code segment, and open files. They also share resources like the process's heap and global variables.

Threads belonging to the same process share the same resources and address space.


What is the difference between processes and threads?

The memory space, where a given application is executed is called - process. A Process is the memory set aside for an application to be executed in. Within this process the thing, which is really executed is the thread. The key difference is that processes are fully isolated from each other; threads share (heap) memory with other threads running in the same application. Threads share the address space of the process that created it; processes have their own address. Threads have direct access to the data segment of its process; processes have their own copy of the data segment of the parent process. Threads can directly communicate with other threads of its process; processes must use inter-process communication to communicate with sibling processes. Threads have almost no overhead; processes have considerable overhead. New threads are easily created; new processes require duplication of the parent process. Threads can exercise considerable control over threads of the same process; processes can only exercise control over child processes.

What resources are typical shared by all of the threads of a 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 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

What is a thread and how does it relate to a process?

A process is composed of one or more threads of execution. Multiple threads allow a process to perform two or more operations concurrently. This is particularly useful in machines with two or more processors as the threads can execute simultaneously. All the threads of a process run in a shared memory space; separate processes run in separate memory spaces. A process must have at least one thread, the primary thread. However, threads can spawn new threads as required. Each thread has its own call stack but shares the same data segment and virtual address space as the process.
