![]() The kernel is at the heart of an operating system, the place where it all begins and ends. It is the foundation that enables an operating system to function and is essential for running software applications. The kernel handles tasks such as memory management, process control, device management, network communication, and security. It is a low-level system that manages the communication between the hardware and software components of a computer. ![]() What’s A Linux Kernel?Ī Linux kernel is the core of a Linux operating system and is the first layer of software that interacts directly with the hardware of a computer. There are only a few requirements for a system to run properly. Microkernels and monolithic kernels are the most common types of Linux. The primary types of kernels are monolithic and microkernels. It includes tasks such as scheduling, resource allocation, device management, interrupt handling, memory management, and process management, in addition to kernel functions. A Kernel is made up of five components: monolithic, microkernel, nanokernel, hybrid kernel, and exokernel. Kernels such as Zircon, Linux, WindowsNT, and others can be used to illustrate how a programming language works. The memory segment of an operating system code that is always present and provides a way for hardware and software to interact. ![]() The kernel manages user requests by using system calls (see Figure 1.1), which move requests from user space to kernel space.Ī computer operating system is typically made up of a kernel, which is a program that serves as the heart of the system. A hardware interface, as well as a program interface, memory, and I/O management, are all included. UNIX, the operating system’s central operating system, is a component of the Linux kernel. We will also provide some tips to help you answer these questions confidently and successfully. In this article, we will discuss what kernel is, its functions and importance, and some common Linux interview questions related to kernel. As such, it is an important topic of discussion in Linux interview questions. It is the central core of a computer system, which manages the resources of a computer and provides the basis for interaction between hardware and software components. Kernel is one of the most fundamental components of an operating system.
