What kernel is Mac OS X based on?
Mac OS X is based on the XNU kernel, a microkernel Mach kernel with a BSD userland, which makes Mac OS X's kernel a hybrid-kernel.
Where does operating system typically resides?
An OS reside in HDD, SSD, flash drive or CD/DVD. When you boot the computer the kernel is copied to RAM. Now other parts of OS will be loaded to RAM as and when required.
What is kernel in UNIX operating system?
kernel is everything in unix os
Definition of OS Kernel Shell?
The kernel and the shell are two different parts of the OS or operating system. The shell interprets the commands from input. The kernel houses the heart of the OS like the command files and execute applications.
Give One difference between operating system software and applications software?
The OS makes calls to the system kernel (although sometimes the kernel is bundled with the OS). Applications make their calls to the OS, which then makes calls to the kernel.
How does Unix facilitate the installation of a new device without recompiling the OS?
This is done via a technique known as a loadable driver; the actual hardware driver is loaded into the system dynamically. Since devices can be loaded and unloaded they do not have to be compiled into the system kernel.
Which kernel platform can be used to run a Macintosh OS X system?
Mac OS X is built on the XNU (X is Not Unix) kernel which is a hybrid combining elements of the Mach kernel and FreeBSD.
Does Mac OS X use a Linux or a BSD kernel?
Mac OS X uses a Mach kernel and FreeBSD utilities at it's core.
Which of the two OS core components includes the windows memory manager?
shell, kernel
What part of the operating system interfaces with the hardware?
the kernel is the part of the OS that interfaces with the hardware
The portion of an OS remains in memory the entire time the computer is on?
The portion of an operating system (OS) that remains in memory the entire time the computer is on is typically the kernel. The kernel is responsible for managing system resources, hardware communication, and providing essential services to other software. Unlike other components that may be loaded or unloaded as needed, the kernel must stay resident in memory to ensure the system operates smoothly and efficiently at all times.
What command can you use to remove a loaded kernel module?
modprob
