What are kernels in metals? Due to low ionization energy, metal has a tendency to lose valence electrons easily & to form positive ion called Kernel. The kernel consists of metal nucleus & inner shell electrons.

What are the advantages of micro kernel architecture? One benefit of the microkernel approach is ease of extending the operating system. All new services are added to-user space and consequently do not require modification of the kernel. The microkernel also provides more security and reliability, since most services are running as user — rather than kernel — processes.

How many types of kernels are there? There are five types of kernels: A micro kernel - A kernel which only contains the-basic functionality; A monolithic kernel - A kernel which contains many device drivers.

What is the main advantage of the microkernel approach how user programs and system services interact in the microkernel architecture? User programs and services interact in a microkernel architecture by using interprocess communication mechanisms for example messaging. Cloud Academy's Black Friday Deals Are Here! Advantages of the microkernel approach is that it makes easier to extend the operating system of a computer, it provides more reliability and-security.
