Study Notes
Operating System Services
- Common Services: Operating systems typically provide services such as process management, memory management, file system management, and device management.
- Not Provided: Services like application-specific functionality or user-specific customization options are not directly provided by the operating system.
Purpose of System Calls
- Definition: System calls are requests made by programs to the operating system to access hardware or services.
- Functionality: They enable user-level applications to perform operations such as reading files, creating processes, and communicating with devices.
Modular Operating System Design
- Strategy: The microkernel architecture involves dividing the operating system into a small kernel with essential functions, while other services and drivers operate as separate modules.
- Benefits: This design enhances system stability and flexibility, as individual components can be updated or modified without affecting the core kernel.
Booting Process of an Operating System
- Steps Involved: The boot process generally includes initializing hardware, performing a power-on self-test (POST), loading the bootloader, and subsequently loading the operating system kernel into memory for execution.
- Final Stage: Once the kernel is loaded, it initializes system services and sets up the user environment.
Kernel Modules in Linux
- Definition: Kernel modules are dynamically loadable object files that extend the functionality of the Linux kernel without requiring a system reboot.
- Uses: They are utilized for adding support for new hardware, filesystems, or network protocols, allowing flexibility and efficiency in managing system resources.
