Latest Syntel Aptitude Question SOLUTION: What is kernel ?

1)The kernel is the most fundamental part of an operating system.
It can be thought of as the program which controls all other programs on the computer.
2)It is responsible for the creation and destruction of memory space which allows software to run.
3)It provides services so that programs can request the use of the network driver, the disk or any other piece of hardware (the kernel forwards that request to special programs called drivers which control the hardware), manages the file system and sets interrupts for the CPU to enable multitasking.
4) Many kernels are also responsible for ensuring that faulty programs do not interfere with the operation of others, by denying access to memory that has not been allocated to them and restricting the amount of CPU time they can consume
5)A kernel is the central part of an operating system. It manages the tasks of the computer and the hardware - most notably memory and CPU time.

There are two types of kernels:

*A microkernel, which only contains basic functionality;
*A monolithic kernel, which contains many drivers.
6)A computer user never interacts directly with the kernel. It runs behind the scenes and cannot be seen, except for the text logs that it prints.

kernel is a term which comes under operating system.
kernel is a interface between hardware and schedulers.
in simple words we can say that operating system is one of the program running at all times on the computer usually known as "kernel".....

Kernel acts as an interface between system hardware and application software.

it is interface b/w hardware and application software
