The UNIX kernel is the central core of the operating system. It provides an interface to the hardware devices as well as to process, memory, and I/O management. The kernel manages requests from users via system calls that switch the process from user space to kernel space (see Figure 1.1).
What is the role of the kernel?
The kernel provides the basic architectural model for isolation, resource and process scheduling, memory management, networking, and device driver interfaces and organization. The kernel is the first layer of abstraction in the platform that insulates software from hardware-specific details.
What is the role of kernel in Linux?
The Linux® kernel is the main component of a Linux operating system (OS) and is the core interface between a computer’s hardware and its processes. It communicates between the 2, managing resources as efficiently as possible.
How kernel plays an important role in operating system?
The Kernel is responsible for low-level tasks such as disk management, memory management, task management, etc. It provides an interface between the user and the hardware components of the system. When a process makes a request to the Kernel, then it is called System Call.
Is Linux a kernel or OS?
Linux, in its nature, is not an operating system; it’s a Kernel. The Kernel is part of the operating system – And the most crucial. For it to be an OS, it is supplied with GNU software and other additions giving us the name GNU/Linux. Linus Torvalds made Linux open source in 1992, one year after it’s creation.
What type of kernel is Linux?

What are the features of kernel?
A core feature of any operating system, the kernel manages communication between hardware and software. The kernel is responsible for managing memory, and I/O to memory, cache, the hard drive, and other devices. It also handles device signals, task scheduling, and other essential duties.
Is kernel a process?
A kernel is bigger than a process. It creates and manages processes. A kernel is the base of an operating System to make it possible to work with processes.
