Microkernel Operating System Design

These flashcards cover key concepts related to microkernel operating system design, including definitions of terms and explanations of benefits and downsides.

Microkernel

A minimal operating system kernel that provides only the most basic services for managing hardware and applications.

Inter Process Communication (IPC)

A mechanism that allows processes to communicate and synchronize with each other.

User Level

The level at which applications and processes run, which is outside the operating system kernel.

Kernel

The core component of an operating system which manages hardware and software resources.

Benefits of Microkernel

Includes lower overheads, better performance, ease of verification, and suitability for critical applications.

Downsides of Microkernel

Questionable portability, software complexity due to specialization, and customization for specific hardware.

Thread

The smallest sequence of programmed instructions that can be managed independently by a scheduler.

Embedded Devices

Specialized computing devices designed to perform dedicated functions often within larger systems.

User Kernel Crossing

The transition of control from user space to kernel space, which can be costly in terms of performance.
