Real time is all about providing a result in a bounded amount of time. It is about juggling multiple inputs from the outside world and supplying outputs back to it exactly when needed. An example of a real-time application is the antilock brakes on your car (they must be accurately pulsed tens of times per second). To satisfy the needs of real-time systems, APIs must be available to support accurate timing, fast communications and I/O, and precise, priority-driven scheduling. Conventional wisdom held that without proprietary APIs and OSes, it was impossible to achieve the level of performance required to solve real-time problems. However, there are significant costs associated with coding solutions to a proprietary product.
Recognizing this, OS vendors, researchers, and users participated in an IEEE working group known as Posix.4. The group’s goal was to refine existing Posix APIs and develop new APIs to address the needs of the real-time environment. The result of this effort was the Posix 1003.1b-1993 standard, or…

A lot of people nowadays are becoming crafty and smart when it comes to reusing or using something other than the purpose that it was meant for. Most of them uses the internal contents of Dell PowerEdge recovery and use it for something else. Many people say instead of buying expensive anti-virus for your computer, you can simply back up your files in this Dell PowerEdge recovery so it can be protected against any other kinds of file corruption no matter what the circumstances are. Other times they try to hack the system and make Dell’s recovery system usable for other brands of computers. That is how smart and clever people are nowadays. The reason why they do this is because they want to save more on protecting their computers. Instead of buying generic brands, they buy these branded recovery systems and hack it and they use it for their device. In this way, they can be sure that they will be protected…
