Operating System Development Concepts

An Operating System (OS) is the fundamental software that manages computer hardware and software resources. It's the brain that makes your computer usable.

In this lesson, we'll explore key concepts behind OS development, particularly how Rust can be used to build a kernel, offering low-level control with modern safety guarantees.

The kernel is the central part of an OS. It's the first program loaded when a computer starts and has complete control over everything.

Its main responsibilities include:

• Memory Management: Allocating and protecting memory.
• Process/Task Management: Scheduling and switching between running programs.
• Hardware Interaction: Handling input/output (I/O) and interrupts.
• System Calls: Providing services to user applications.
