The kernel is the core component of an operating system, responsible for managing system resources like CPU, memory, and device control.
The Scheduler is responsible for determining which processes run at any given time on the CPU, optimizing the use of resources.
The creat() system call is employed for creating files in Unix-like systems. It sets the file size to zero if it already exists.
Modular kernels permit components or modules to be added or removed during runtime, offering increased flexibility and scalability.
Context-switching overhead refers to the time and resources required to switch the CPU's focus from one process to another, impacting performance.
The Memory Manager in the kernel undertakes tasks related to memory protection, ensuring that processes do not interfere with each other's memory spaces.
A thread is considered lightweight because it executes within a process's context and shares the process's resources while operating independently.
The syscall interface provides a controlled means for user applications to interact with the kernel, such as inquiring system state or performing I/O operations.
While the kernel manages a file system and a network stack, an API is not part of the kernel structure. It is a set of functions for applications.
Paging enables more efficient use of RAM by creating a virtual address space, managing memory in fixed-size blocks, and ensuring process isolation.
