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 difference process based and thread based multitasking?
-> Difference between process based and thread based multitasking: 1) threads share the same address space where as process doesn't. 2) context switching between threads is usually less expensive than between processes. 3) cost of communication between threads is relatively low.
What is the relationship between threads and multiprocessing?
Processes are made of threads; threads within a process can be handled by different processors to improve server performance.
Difference between child process and threads in operating systems?
One difference is that, when the main program terminates, all its threads are terminated. It is not the case for processes, because they are kind independent of the parent. When the parent terminates, the process keeps going unless the parent waits for it to die.
Is there any difference between pipe threads PT and national pipe threads NPT?

Whats the difference between plumbing pipe threads and conduit pipe threads?
Plumbing pipe threads are squared and conduit pipe threads are tapered.
What is the difference between pipe threads and electrical conduit pipe threads?
Water pipe threads are tapered, electrical pipe is not tapered.
What is the difference between single and double screw threads?
screw thread are single threads which means they are not double
What is the difference between rigid electrical pipe and plumbing pipe?
The threads
What are the similarities between process and thread?
Unlike processes, threads are not independent of one another.Unlike processes, all threads can access every address in the task .Unlike processes, thread are design to assist one other. Note that processes might or might not assist one another because processes may originate from different users.
What is the difference between capillitial threads and a columella?
Capillitial threads are very minute forms of slime mold. A columella has numerous threads radiating from all sections of the cell.
What is the difference between pipe threads and bolt threads?
NPT = pipe Briggs standard = Pipe NFT and NFC and ASAE = bolt
Compare and contrast between threads and classes in java language?
A thread is like any other class, except that there is the capacity to run multiple threads - multiple processes - simultaneously.
