1-Define, in your own words, "multitasking" and "real-time" in terms of embedded system? 2-Explain why embedded system processor would use concurrent processes to control an alarm system in a home. Door and Window switches, motion detector all controlled through a central panel. Assume all the features of the alarm system are under software control Then, list at least 3 of the processor that might be needed. Use pseudo code or flow diagrams to demonstrate what each process does. Thank you very much for your valuable time!!Explanation / Answer
An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. Application programs usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently make a system call to an OS function or be interrupted by it. Operating systems can be found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems include Android, BSD, iOS, Linux, Mac OS X, Microsoft Windows, Windows Phone, and IBM z/OS. All these, except Windows and z/OS, share roots in UNIX.
