The major difference between threads and processes is
1.Threads share the address space of the process that
created it; processes have their own address.

2.Threads have direct access to the data segment of its
process; processes have their own copy of the data segment
of the parent process.

3.Threads can directly communicate with other threads of
its process; processes must use interprocess communication
to communicate with sibling processes.

4.Threads have almost no overhead; processes have
considerable overhead.

5.New threads are easily created; new processes require
duplication of the parent process.

6.Threads can exercise considerable control over threads of
the same process; processes can only exercise control over
child processes.

7.Changes to the main thread (cancellation, priority
change, etc.) may affect the behavior of the other threads
of the process; changes to the parent process does not
affect child processes.
