What is independent of the operating system?
It means that it has been written in a way, that it can be compiled (if compilation is necessary for the language used) or run without or just little modification on several operating systems and/or processor architectures. For example, openGL is a library which is OS independent.
Why the OS software is not independent of the processor?
There are different CPUs, each working differently and having a different “native language”. Since an OS is “just a program” which needs to run on the CPU, it must be written in the CPUs native language is thus dependent on it. You cannot run a normal Windows on an ARM or PowerPC processor, for example.
How does operating system work with processor?
CPU Control Your computer’s processes are executed by its central processing unit, or CPU. Signals sent to and from the CPU determine what happens, and in what order. The operating system works with the CPU to create a checklist of processes to execute and ensures that each gets done.
What are the 3 characteristics of an operating system?
The Operating systems are different according to the three primary characteristics which are licensing, software compatibility, and complexity.
What is device dependent operating system?
Like machine-dependent, device-dependent refers to programs that can run only on a certain type of hardware (i.e., their ability to function depends on the devices on which they run).
What are device independent and device dependent drivers?
Device independent components work right no matter what model of device you use them with. Device dependent components by contrast, work right only with a particular model of the device.
Which is independent of hardware and the operating system?
Explanation: The operating system is software which provides a buffer between the low-level interfaces to the hardware within the system and the user. 2. Explanation: The operating system allows the software to be moved from one system to another and therefore, it can make the application program hardware independent.
Can any OS run on any processor?
That would depend on the OS and the processor. Windows, for instance, used to support various processors, but currently only supports the Intel i86. Other OSes such as Android run on many different processors.
Why does the OS need to manage the processor?
The operating system’s most important job is managing the CPU: If there are multiple programs that must execute, then it is a disaster if one program uses the processor and “loops. ” The OS must ensure that all programs have fair use of the processor’s time so that all programs make progress at execution.
