Introduction The system call is a mechanism in Linux that allows user-space applications to connect with the kernel, which is also a component of what makes up the operating system's core. A user-space application needs to send a system call to the kernel that is used to have a privileged functioning performed on its behalf, including writing or reading information to a file or beginning a new process. In this article, we will be discussing the Linux System Call in detail along with its various types. How Linux System Calls Work? The system calls are carried out in the kernel ... Read More

A linked list is made up of nodes, each of which has a data element and a pointer (or reference) to the node after it in the list. Each node in dynamic partitioning represents a memory block that can be assigned to a process. The linked list initially reflects the whole memory block that is accessible. In this article, we will explore the Linked List for Dynamic Partitioning, what Dynamic Partitioning is in Memory Management, and also the implementation of Linked List in Dynamic Partitioning. Dynamic Partitioning in Memory Management Computer systems employ the memory management approach known as "dynamic ... Read More

A technique for categorizing material on a storage device, like a hard drive, is Linked Index Allocation. It is a variant of the indexed allocation technique, which keeps track of the locations of the data blocks using an index block. Each data block in Linked Index Allocation includes a pointer to the location of the following data block in the file. Up until the last data block, which contains a pointer to a special value signifying the file's end, the first data block of the file contains a pointer to the second data block, the second data block contains a ...

Introduction Linear Scheduling Method is a scheduling algorithm designed for real-time systems in which tasks must be completed within specific time frames to ensure the system's proper operation. It is a straightforward algorithm that assigns tasks based on their deadlines and provides them with fixed time slices to complete their execution. In this article, we will learn about the Linear Scheduling Method its various elements, its advantages and disadvantages of usage in an Operating System What is Linear Scheduling Method in Operating System? The tasks in LSM are arranged in a linear order, and the scheduler moves through the list, ... Read More

An operating system (OS) is a group of programs that controls computer hardware resources and offers standard services to software applications. The Operating System (OS) serves as a conduit between you and the computer components when you first use a computer system. The operating system is actually a type of low-level software known as a "system software, " which powers a computer's fundamental operations like memory management, task scheduling, and peripheral control. Overview and History of Kylin OS The National University of Defense Technology (NUDT) in China created the Linux-based operating system known as Kylin. Since its initial introduction ... Read More

Knoppix is a Linux-based operating system that runs directly from a CD, DVD, or USB drive without the need for installation. It's often used as a tool for system recovery, testing hardware, and demonstrating the capabilities of Linux. Knoppix Operating System Knoppix was created by Klaus Knopper, a German computer science teacher in the year 2000. It is a Linux-based operating system that can be run directly from a CD, DVD, or USB drive, without the need for installation. Knoppix is useful for various purposes like web browsing, multimedia playback, office applications, and system administration. It comes with a wide ... Read More

A kernel is the core component of an operating system that acts as a bridge between the hardware and software. It manages system resources such as memory, CPU, and input/output devices, and provides a layer of abstraction between the hardware and higher-level software components. Functions of a Kernel Device Management A kernel manages the various peripheral devices connected to the computer and controls them using device drivers. Memory Management A kernel controls the computer's memory and allocates it to processes safely. It uses virtual addressing to prevent processes from crashing into each other. Resource Management A kernel shares resources between ... Read More

The Kernel I/O Subsystem is a fundamental component of modern operating systems. It is responsible for managing all input/output (I/O) operations on a computer. The I/O subsystem provides various services that enable efficient and secure management of the I/O operations. I/O Request Scheduling in the Kernel One of the key services provided by the I/O subsystem is the scheduling of I/O requests. Scheduling involves determining the best order in which to execute I/O requests to improve system performance, share device access permissions fairly, and reduce the average waiting time, response time, and turnaround time for I/O operations to complete. ...

The file systems ZFS (Zettabyte File System) and UFS (Unix File System) are both used in Unix-based operating systems. While both have been designed to manage and store data, they have numerous fundamental differences. ZFS is a modern file system that prioritizes data integrity and provides better levels of data protection and security through features such as checksumming, snapshots, and RAID-Z. UFS is an older file system developed in the early days of Unix that lacks some of ZFS's advanced features and scalability. Read this article to find out more about ZFS and UFS and how they are different from ... Read More
