Why is Linux called a kernel and not an OS?
Linux by its nature is not an operating system; it’s the kernel. The kernel is part of the operating system – and most importantly.

An operating system is a set of software for making use of a computer, and since there are many types of computers, there are many definitions of an operating system. Linux cannot be considered an entire operating system because almost every use of a computer requires at least one additional software.
What are kernel processes?
The kernel process inherits the environment of its parent process (the one that calls the creatp kernel service to create it), but with some exceptions. The kernel process has no root or current directory at initialization. All uses of the file system functions must specify absolute path names.
What are the 5 Kernels? The kernel is the main and central component of the operating system. It has five types, namely monolithic nucleus, microkernel, hybrid nucleus, nano nucleus and exo nucleus. The kernel’s functions include access to computer resources, memory management, device management, and resource management.
How does the kernel manage processes?
The kernel stores a list of processes in a circular, double-linked list called a task list3. Each item in the task list is a process descriptor of type struct task_struct which is defined in. A process descriptor contains all information about a specific process.
How does Linux kernel manage processes?
In the Linux kernel, the process is represented by a fairly large structure called task_struct. This structure contains all the necessary data to represent the process as well as tons of other data for accounting and maintaining relationships with other processes (parents and children).
How does the kernel create a process?
A kernel process is created by a kernel mode routine by calling the creatp kernel service. The creatp kernel service allocates and initializes a process block for the process and sets the new process state to idle.
What is kernel processes and user processes?
User space processes have their own virtual address space. Kernel processes or threads do not have their own address space, they only run in the kernel address space. They can be started before the kernel starts any user process (eg init).
