Are Word and PowerPoint different processes or threads of a single process?

They are different processes. While both are part of the Microsoft Office suite, and their data is stored in the same area of the Windows Registry, they are two different executable programs.
If you open the Task Manager, then click the processes tab, you can see that they are running as different processes.

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 is processes threads?
different paths of control in a program that a computer might run at the same time if it has parallel processing support for multithread execution. threads and processes are two ways of supporting multitasking on a uniprocessor or multiprocessing on a multiprocessor. threads are lighter weight: take less OS resources to implement but only support limited protection and security. processes take more OS resources but can support full protection and security. Many operating systems support both processes and threads, allowing each process to have many threads.
What is relationship between process and thread?
Process --1------------m-- Threads 1 process to many threads Bring up your Task Manager (if you are using a windows), Performance tap, you can see the number of process and the number of threads, usually the number of threads is a lot higher than the number of processes.
If process stop its execution will thread also stop or it will continue to run?
Processes do not execute, it is the threads within a process that actually execute. All processes have at least one thread of execution, the main thread. If the main thread falls from scope, the process ends, taking all threads with it. This can lead to undefined behaviour if the threads are not terminated gracefully from within the main thread before it falls from scope.
What is your club penguin account password?
Processes are made of threads; threads within a process can be handled by different processors to improve server performance.
What do you mean by overhead in process and why do threads dont have overhead?
Process has it's own address space while threads are using process's address space when process is switching from one to another it will save process data during that time no productive work will done by cpu, while threads are using process's data so it can directly switch from one thread to other that's why processes have overhead when they are switching from one to other while threads doesn't have overhead.
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.
Difference between child process and threads in operating systems?
In operating systems, a child process is a new process created by an existing process, which operates independently and has its own memory space. Whereas a thread is a subset of a process, sharing the same memory space and resources as the parent process. Threads are lighter weight and more efficient compared to processes in terms of resource utilization.
What resource are typically 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).

Why thread is called light weight process?
Threads are implemented by a library that utilizes underlying kernel-supported threads of control, called light-weight processes (LWPs). http://java.icmc.usp.br/books/os/html/threads_lightweight_process.html
What is the difference between Light-weight process and heavyweight process?
Light weight process are the process are the processes which is considered for the os as less burden like thread.means the threads are executing inside a process which share the same code and data also memory space of a single process that's it has a less burden to the os and considered as a light weight process.also the communication between the threads are much more efficient. where as in case of a heavy weight process for doing multiple task the os has to create multiple processes which have a multiple memory address space and for communication between them they have to use inter process communication using sockets and pipe and which has more burden on the os than the threads(ligt weight processes) and hence considered as a heavy weight process
