According to Andrew Tannenbaum, the creator of Minix and the author of Operating Systems: Design and Implementation, the two chief tasks of an operating system. The first function is to provide an abstraction layer above the hardware that is easier to program than the bare hardware. By providing this function, the user is freed from the need to worry about interrupts, timers, memory management and other low-level functions. The second function of an operating system is to manager all the various resources of the computer (CPU time slices, RAM, printing etc.) and dole them out wisely among all the various programs competing for them. As an example, let's look at the printer. Imagine if three programs were trying to send output to a printer at the same time. Without an operating system managing the resources, the result would be chaos: a few lines from program 1, a few lines of program 2, a few line from program 3, etc.

What are the main features of the Open Home operating system?
The Open Home operating system does not exist and no results can be found for it. The main operating systems are Windows, Linux and Mac OS. An open home operating system may be a computer without an operating system.

Software enables the computer to perform essential operating tasks.?
The operating system.
Is this true or false an operating is the primary software that runs on a computer?
It's true. The operating system is the main set of instructions the computer needs to enable it to work. Without the operating system, the other programs couldn't interact or perform their tasks.
What are the main Types of operating system?
Main Types of operating system are WindowsMac OSLinuxSun Solaris
What type of operating system do devices that perform regimented tasks or record precise results require?
Devices that record precise results require a real-time operating system. This is the same kind of operating system needed for a device hat performs regimented tasks.
What are the function of operating?
The functions of an operating system include booting the computer and performing basic tasks. The operating system manages the keyboard and mouse. It provides a graphical user interface.
What are the main features of the Open Home operating system?
The Open Home operating system does not exist and no results can be found for it. The main operating systems are Windows, Linux and Mac OS. An open home operating system may be a computer without an operating system.
What is the Software that helps a computer perform essential operating tasks and enables other software to run is?
The software that helps a computer perform essential operating tasks and enables other software to run is the operating system.
What are main differences between cooperative multitasking and preemtive multitasking?
Preemptive multitasking is when the operating system preemptively interrupts a current task without cooperation. Cooperative multitasking is when the system must be programmed to do tasks.
