Two threads can share a common address-space(memory area in RAM).
But 2 process NEVER share address space. Each process has different address space.

A thread in computer science is short for a thread of execution. Threads are a way for a program to split itself into two or more simultaneously (or pseudo-simultaneously) running tasks. .
A process is a running instance of a program, including all variables and other state.
Threads and processes differ from one operating system to another, but in general, the way that a thread is created and shares its resources is different from the way a process does.
At least one thread exists within each process.
Differences:
1.Processes are independent and carry considerable state information.
2.Have separate address spaces
3.Interact only though the system-provided mechanisms.
4.A process is the "heaviest" unit of kernel scheduling.
Threads on the other hand
1.Share state information of a single process
2.Share memory and other resources
3.Context switching between different threads is faster than between different processes.
4.A thread is the "lightest" unit of kernel scheduling.
Have a nice day...

A thred is part of the process but not the whole process just like a finger isn't a hand.
