2. What Is Kernel
-It is Central Core of Operating System control every thing which
included in system.
Start Up
Data
processing
Input -Output
Configura
tion
Memory
Mangeme
nt

3. What is Microkernel
-It is software which provides mechanism needed to implement an
operating system
-Includes low-level address space management, thread
management, inter process communication
-Unlike mono kernels, device drivers, protocol stack, file system and
other low level system develop on user space

5. Advantages
-Increased Security and stability resulting from reduced amount of
code running on kernel mode
-Without recompiling added new features
Examples:-
If Network service crashed due to buffer overflow then only
network service memory corrupt others services are still functional

6. IPC(Inter Process Communication)
-It is mechanism which allow separate process to communicate
with each other usually by sending message
-Microkernel allows operating system to built number of small
program called servers which are used by other program on system
invoked via IPC
