Did/Does OS/360 support or include a microkernel?

Answer 1

Yes, OS/360 support a microkernel:-

• Microkernel

– Popularized by its utilization in the MACH O/S

– The approach gives a high level of adaptability and

particularity

– The approach utilized in Windows NT

• Claims particularity, movability as key advantages

• Microkernel encompassed by a number of minimal

subsystems facilitating assignment of actualizing NT on

assortment of stages

• Microkernel

– Philosophy – just significant center working

framework capacities ought to be in the portion

– Less basic administrations and applications are based on the

microkernel and work in client mode

– Characteristic here is that numerous administrations generally

thought of as a component of the O/S are presently outside subsystems

that communicate with the part and with one another

• Device drivers

• File frameworks

• Virtual memory supervisor

• Windowing framework

• Security administrations

• Microkernel Architecture

– Replaces conventional vertical layered stratified O/S with

level one

– O/S parts outer to microkernel are actualized

as server forms, communicating with one another on a companion

the premise, by going messages through the microkernel

– Hence microkernel works as a message trade

• Microkernel

– Validates messages

– Passes messages between parts

– Grants access to H/W

• Microkernel Benefits

– Uniform Interfaces

– Extensibility

– Flexibility

– Portability

– Reliability

– Distributed System Support

– Object-Orientated Operating System (OOOS)
