Following are some of the major differences between the thread and the processes :
- Processes do not share their address space while threads executing under same process share the address space.
- From the above point its clear that processes execute independent of each other and the synchronization between processes is taken care by kernel only while on the other hand the thread synchronization has to be taken care by the process under which the threads are executing
- Context switching between threads is fast as compared to context switching between processes
- The interaction between two processes is achieved only through the standard inter process communication while threads executing under the same process can communicate easily as they share most of the resources like memory, text segment etc
