Simplicity. The micro-kernel approach to system design keeps the kernel as small and simple as possible. This means that it is easier to maintain, and will likely contain fewer flaws. However, functionality not implemented inside that kernel (like device drivers) will need to be provided in another way, usually by other programs.

The kernel is the core part of the operating system. The kernel handles the machine side of things, while the GUI handles the user side of things.
The main advantage of the layered approach is modularity. The layered are selected such that each uses function and services of only lower level layers. This approach simplifies debugging and system verification In this case the system is easier to debug and modify, because changes affect only limited portions of the code, and programmer does not have to know the details of the other layers. Information is also kept only where it is needed and is accessible only in certain ways, so bugs affecting that data are limited to a specific module or layer. Regards Praveen Muttikkal
The kernel is the essential center of a computer operating system the core that provides basic services for all other parts of the operating system. A kernel is designed to be a central core to the operating system - the logic that manages the resources that the hardware has to offer.
The kernel is one of the primary nodes of an operating system for a computer. It contains operating system core functions and the device drivers.
Microkernels provide minimal process and memory management, in addition to a communication facility.
Linux kernel is an operating system that is distributed by open source software. It is based on Unix, but has some differences, some of which are in adding and removing features of the kernel, kernel threading, application support, and monolithic kernel approach.

The Kernel
Traditional approach, Current practice approach, reaction approach, cafeteria approach, human service approach
Yes, they are the interface to kernel functionality. To quote wikipedia: a system call is how a program requests a service from an operating system's kernel that it does not normally have permission to run
kernel is everything in unix os
when a process or anything makes a system call ,it goes in kernel(operating system).
The kernel is the core part of the operating system. The kernel handles the machine side of things, while the GUI handles the user side of things.
The Linux kernel is the central component of the GNU/Linux operating system. The kernel is the lowest level of interaction between the hardware and the operating system. Individual applications are at a higher level. The kernel along with supporting applications make up the operating system.
