In Linux, there is no difference between threads and process. It is like, a thread is merely a process that shares certain resources with other processes. Each thread has its own process descriptor and appears to kernel as a normal process - threads just happen to share resources, such as an address space, etc
The approach is different in other OS such as Microsoft Windows or Sun Solaris, which have explicit kernel support for threads. To these threads are an abstraction to provide a lighter, quicker execution unit than the heavy process. Suppose you have a process with four threads. In Windows you will have one process descriptor that points to all its threads. In Linux you would have four process descriptors with some sharing between them.
