The architecture of an operating system can be divided into several layers:
1. Hardware Layer - This layer includes the physical hardware components of a computer such as CPU, memory, I/O devices, etc.
2. Kernel Layer - The kernel is the core of the operating system. It manages the system resources, provides services to the applications, and acts as an interface between the hardware and the software.
3. System Call Layer - This layer provides an interface between the applications and the kernel. Applications can request services from the kernel through system calls.
4. Library Layer - This layer includes libraries that provide common functions to the applications, such as file I/O, networking, and graphics.
5. Application Layer - This layer includes user-facing applications such as web browsers, media players, and text editors.
These layers work together to provide a stable and secure environment for running applications on a computer.
