Define the WindowsNT
WindowsNT provides a two-level approach to resource management: process and thread. The process is the uppermost level and contains most of the application resources. Each process is started with one thread (the Main Thread) and may create peer threads. Each of these threads may access code, data, and resources allocated to its parent process.
In addition, inherited resources may be provided by creating new child processes. The CreateProcess( ) command provides a mechanism for specifying the level of inheritance for child processes. Resources (or object handles) such as files, semaphores, threads, pipes, current directory, stdin, stdout, and environment variables may be inherited.
