Compare Thread and process.
A thread is associated with a process. A process can have multiple threads
running. When an application is started, a process is invoked and the process
owns the memory, resources, and threads of execution that are associated with a
running instance of an executable program. The program runs until the thread is
associated with that process. A thread is the smallest unit of execution that
is intact to a process.

Compare Thread and process.
Threads
Share address space
Have direct access to data segment of its process
Can communicate with other threads of the same process
Have no overhead
If a main thread gets affected, other threads to can get affected
Processes
Have own address space
Have own copy of data segment of the parent process
Processes must use IPC for communication within sibling processes
Have considerable overhead
Change in a parent process has no effect on the child processes.
