Threads are the smallest unit of processing that a scheduler can work, and can have the same resources such as memory, address space, open files. Also called "light weight processes (LWPs).

Threads vs Processes:

• Threads
  • executing under the same process share the address space.
  • Communication between threads is very fast because they share same address space.

• Processes
  • Processes do not share their address space.
  • Communication between process is quite difficult and resource intensive.
