Product Overview ICP-PIII
1.3 Software
1.31 Linux
Being a modern operating system, Linux executes a 32-bit architecture, uses pre-emptive multi-
tasking, has protected memory, supports multiple users, and has rich support for networking,
including TCP/IP. Linux was originally written for Intel’s 386 architecture, but now runs on a wide
variety of hardware platforms including the full x86 family of processors as well as Alpha, SPARC,
and PowerPC.
Linux’s architecture also creates a more reliable and inherently stable system through the use of
protected memory and pre-emptive multitasking. Protected memory prevents an error in one
application from bringing down the entire system, and genuine multitasking means that a bottle-
neck in one application does not hold up the entire system. Linux also maintains a very clean
separation between user processes and kernel processes. While other server class operating sys-
tems use protected memory this feature is prone to failure if faulty applications are allowed to
invade kernel space with their processes.
1.32 VentureCom
Hard, real-time scalability and embedded operation extensions are required for Windows NT by
HAL modification for deterministic interrupt handling at multiple priority levels. This approach
achieves response times in the
µ
s range and reduces hardware resource requirements while main-
taining full compatibility with the enormous range of standard software and device drivers written
for the Windows NT operating system.
1.33 Windows 2000
Windows 2000 is highly reliable and available 32-bit OS.
Support for USB devices allows connection of peripherals without the need to reboot the system
and unlike Windows NT 4.0 support is also provided for the IEE1394a (FireWire) devices. Finally,
secure, wireless communication between two Windows 2000-based computers is possible using
the popular IrDA infrared protocol.
Removable storage devices such as DVD and Device Bay are supported as are new display devices
such as Accelerated Graphics Port (AGP), multiple video cards and monitors, OpenGL 1.2, DirectX®
7.0 API, and Video Port Extensions.
With Plug and Play automatic installation of new hardware is possible with only minimal configu-
ration. More than 12,000 devices now support this functionality.
