parwo se izwinqwam za latinicata koqto polzwam ... LIVE-CD :)

ta po temata
iskam da popitam ima li nqkoi koito da mi obqsni kakwo w deistwitelnost predstawlqwat "Realno-wremewite" OS
kakwi sa predimstwata i nedostatacite im
nakratko kazano koito kwoto znae za RealTime OS da pi6e

blagodarq predwaritelno za otgoworite

What is a realtime system?
Some environments call for more rigorous resource management and scheduling than others. Realtime applications, for instance, depend on the OS to handle multiple events and to ensure that the system responds to those events within predictable time limits. The more responsive the OS, the more ``time'' a realtime application has to meet its deadlines.

The QNX/Neutrino Operating System is ideal for embedded realtime applications. It can be scaled to very small sizes and provides multitasking, threads, priority-driven preemptive scheduling, and fast context-switching - all essential ingredients of a realtime system. Moreover, the QNX/Neutrino OS delivers these capabilities with a POSIX-standard API; there's no need to forgo standards in order to achieve a small OS.

QNX/Neutrino is also remarkably flexible. Developers can easily customize the OS to meet the needs of their applications. From a ``bare-bones'' configuration of a kernel with a few small modules to a full-blown network-wide system equipped to serve hundreds of users, QNX/Neutrino lets you set up your system to use only those resources you require to tackle the job at hand.

QNX/Neutrino achieves its unique degree of efficiency, modularity, and simplicity through two fundamental principles:

microkernel architecture
message-based interprocess communication
