<h2>introduction</h2>
<div>
<p>
Building an operating system requires understanding of both hardware and software fundamentals.
This post will cover the basics of boot process, memory management, and process scheduling.
</p>
</div>
<h2>boot process</h2>
<div>
<h3>bootloader</h3>
<div>
<p>
The bootloader is the first piece of code executed when a computer starts up.
It's responsible for loading the operating system kernel into memory.
</p>
</div>
<h3>kernel initialization</h3>
<div>
<p>
After the bootloader loads the kernel, the kernel initializes various hardware components
and sets up memory management, interrupt handling, and other core services.
</p>
</div>
</div>
<h2>memory management</h2>
<div>
<p>
Memory management is a critical component of any operating system.
It involves tracking and allocating memory to processes, handling virtual memory,
and implementing paging or segmentation.
</p>
</div>
<h2>process scheduling</h2>
<div>
<p>
Process scheduling determines how CPU time is allocated to different processes.
Various scheduling algorithms like round-robin, priority-based, and shortest job first
can be implemented depending on the use case.
