Microkernel vs Monolithic Kernel Design Trade-offs

Abstract

Abstract - In the operating system, there are different kernels, but in this paper, we will discuss two kernels: monolithic kernel and microkernel. Monolithic kernels are a bit risky in that they have everything like all in an imagined operating system which has a large amount of code that contains all the essential components like memory management and file handling monolithic kernels have direct access to everything if there is an issue entire system will be collapsed. Microkernels are like organised toolboxes with different components of each tool. In microkernel they are divided into parts like one handle memory and other handles files by dividing like this they mess with each other, and security also improves. The research includes a literature review that consists of the pros and cons of the two monolithic kernels kernel pros are easy to understand it is like one tool that gives you all the information and another is its efficiency everything will be together with less fuss. its like having all your required tools in one place. Cons they are inflexible. You can't swap out tools or make changes easily. They are risky if something goes wrong, it will affect the entire system. Microkernel Pros Dependability If one of the components misbehaves it won't mess with the other components.it is like a firewall between them. security they are divided into small. components mean fewer vulnerabilities. It is like locking each component securely. Cons performance in microkernels the components are divided into small categories due to this there will be extra communication between components it's like sending a component back and forth to another one complexity managing all these separate components and they can be arranged in a puzzle and it is worth for the security. In summary, monolithic kernels offer simplicity and efficiency but lack flexibility. Microkernels prioritise dependability and security.
