Linux Kernel

Linux is the core of the Operating system i.e., it is the kernel. It is the closest thing that runs to the underling hardware such as CPU, Memory and I/O devices i.e.

• It controls CPU

• It controls Memory

• It controls Devices

Note it is possible to change the Linux Kernel i.e., basically one can install or update the Linux kernel since it is open source, but the same cannot be done with Windows since NT kernel is closed source.
