Since the operating system is such a complex structure, it should be created with utmost care so it can be used and modified easily. An easy way to do this is to create the operating system in parts.
What is microkernel OS?
In computer science, a microkernel (often abbreviated as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC).
How does an OS work?
It works as an intermediary between the hardware and any programs that are being run on the mobile device or computer. Some of the things that operating systems help accomplish include managing inputs from users, sending output to the output devices, management of storage spaces and control of peripheral devices.
What are the functions of OS?
An operating system has three main functions: (1) manage the computer’s resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.

Here is a partial list of what an OS must manage: the CPU: The OS must decide which programs are executed by the CPU and for how much time. This is called processor scheduling. The OS also provides the interrupt-handling programs that the processor executes when an input/output device signals an interrupt.
What is the purpose of a device driver?
A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details of the hardware being used.
How do you develop device drivers?
- Step 1: Know about the Hardware.
- Step 2: Say Hello to your hardware (In other words, talk to your hardware)
- Step 3: Initialize your hardware.
- Step 4: Control your hardware.
- Step 5: Data Communication to your hardware.
- Step 6: Start and Stop data communication.
- Step 7: Fine-Tune and Debug Your Driver based on Testing.
What are the types of device drivers?
For almost every device associated with the computer system there exist Device Driver for the particular hardware.But it can be broadly classified into two types i.e.,
