Key Differences
The Kernel, a fundamental part of the OS, manages hardware resources, memory, and processes. It acts as a bridge between software and hardware, handling tasks like memory management and process scheduling.
The OS encompasses the Kernel and additional software components. It provides user interfaces, file management, and system utilities, enabling users to interact with the computer and run applications.
Directly interacting with the hardware, the Kernel handles critical tasks like managing memory, I/O operations, and process execution. It's responsible for ensuring system stability and resource allocation.
The OS includes a graphical user interface (GUI) or command-line interface (CLI), application software, and system utilities. It facilitates user interactions, file management, and application execution.
Acts as the core component, enabling software to communicate with hardware. It handles low-level functions, ensuring proper execution of system calls and managing hardware resources efficiently.
