The shell is made up of several subsystems that all operate in user mode. The kernel, or core, of the OS is responsible for interacting with hardware. It has more power to communicate with hardware devices than the shell has, and operates in kernel mode.

Windows and UNIX have distinct architectures. Windows Architecture: It consists of a layered structure with a kernel at the core, managing hardware interactions, system calls, and user mode applications. Above the kernel are various subsystems, including the Windows API, which provides applications with the necessary services and functionalities. UNIX Architecture: UNIX follows a modular design, featuring a kernel that interfaces directly with hardware and manages system resources. User applications run in user mode, interacting with the kernel through system calls, while the shell provides a command-line interface for user interaction. Both architectures emphasize separation between user space and kernel space for stability and security.
