Question

Which of the following is facilitated by microkernel?


a. Reliability

b. Extensibility

c. Portability

d. All of the above​

Answer 1

Answer:

Extensibility

Explanation:

Microkernel provides a mechanism of managing services in kernel. Services can be of 2 types :- 1) User services 2) Kernel Service

Both of these services are implemented in different address space. So there is no interference of one with other. If provides an extensible architecture.

If any new user service is to be added, it is added without any impact of kernel service just make it easily extensible.

Answer 2

Answer:

(b) Extensibility  is facilitated by microkernel

Explanation:

Microkernel: This an architectural pattern which is natural. This is useful to implement in applications which are product based.

Microkernel has features like “extensibility, flexibility and isolation”.

There are two types of architecture. They are Plug-in modules and core system. This provides extensibility by dividing the application logic into plug-in modules and core system.

Core system makes system operational and perform minimum number of activities. Whereas plugin models are independent component.
