<< Thread >>
- Consume less resource.
- In multi-thread, when a thread calls exit() then all the threads will be exited.

<< Process >>
- The resource is duplicated.
- If Parent or Child calls exit(), then it doesn’t affect to the other as Parent and Child process is independent. If one dies, the other still alive.
- In case we have a code that can easily cause errors (i.e : open/close file, access to pointer, system call…) And we don’t want our program to be crashed because of that code, then we could separate the process by using fork().
- The parent process will run the main code.
- The child process will run the “risky” code. 
- If the crash happens, the child  will die, and the parent process will be still alive.
