  3. What language(s) is NT written in, and why this choice? 5. NT offers both binary- and source level compatibility with applications other than its own WIN32 API.

  4. Feb 24, 2009 · For those who care about such things: Many have asked whether Windows is written in C or C++. The answer is that - despite NT's Object-Based design - like most OS', Windows is almost entirely written in 'C'. Why?

    Usage example

    Most of the source code for Windows NT is written in C or C++.
  5. • Reliability — NT uses hardware protection for virtual memory, and software protection mechanisms for operating system resources. • Compatibility — applications that follow the IEEE 1003.1 (POSIX) standard can be complied to run on NT without changing the source code. • Performance — NT subsystems can communicate with one

  7. Foundation for the executive and the subsystems. Never paged out of memory; execution is never preempted. Four main responsibilities: thread scheduling. interrupt and exception handling. low-level processor synchronization. recovery after a power failure. Kernel is object-oriented; uses two sets of objects.

  8. especially Windows NT™, has become a critical succe ss factor. This paper is written for IT professionals with a strong background in Unix. It begins by describing the architecture of Windows NT in a technical framework that is common to Unix. This section also serves to bridge the gaps in terminology between Windows NT and Unix.
