When managing our Linux systems, one of the most crucial things to consider is how we manage our disk space. Many of us are not aware of this, As we accumulate files and directories on our system, it's easy to lose track of what's taking up space and how to optimize our disk usage. But don't worry, that's where dutree comes in handy! In this article, we'll look into dutree in detail. We'll cover what it is, how to use it, and what benefits it offers for analyzing disk usage in Linux systems. Whether you're a Linux beginner or an ... Read More

What is Centralized Clock Synchronization? The process of internal clock synchronization in which different clocks of a system are synchronized with one standard clock of the system is referred to as centralized clock synchronization. In other words, an internal clock synchronization approach where the system clock is synchronized across all devices in a network with the help of a centralized server is referred to as centralized clock synchronization. The centralized clock synchronization is important to ensure the smooth operation of all devices in the network that are operating and communicating with each other on the same timeline. The centralized ... Read More

In any computer system, the Operating System (OS) is the most important system software that creates an interface between a computer user and the computer hardware, and also manages all the system resources. The operating system is a software that performs all the necessary basic functions like file management, memory management, process management, input and output handling, and controlling of peripheral devices, such as disk drives and printers. The operating system is entirely responsible for creating a user interface and providing a platform to work all other software applications. However, like any other software of a computer system, the operating ... Read More

A computer system that is specially designed to work and respond the external events in a timely and predictable fashion is referred to as a real-time system. Read this tutorial to learn the basic model of a real-time system. But before that let’s have a look into the basics of a real-time system. What is a Real-Time System? A computer system that is capable of responding to external events in a timely and predictable fashion is referred to as a real-time system. Real-time systems are commonly used in various applications, such as industrial automation, robotics, automotives, medical instruments, scientific and ... Read More

Laptop and Chromebook are two widely used modern personal computers which are commonly used by students, office professionals, programmers, etc. The fundamental difference between the two is that a laptop is a type of personal computer having a portable design and used for performing general purpose tasks like word processing, internet browsing, gaming, and more; whereas a Chromebook is a type of laptop computer that has the Google Chrome Operating System (Google Chrome OS). Similar to any other laptop, the Chromebook is also used for general purpose tasks. Read this tutorial to learn more about Laptops and Chromebooks and ... Read More

Operating systems use a particular kind of scheduling algorithm called multilevel queue scheduling to control how resources are distributed across distinct tasks. It is an adaptation of the conventional queue-based scheduling method, in which processes are grouped according to their priority, process type, or other factors The system can allocate system resources based on the priority and needs of the processes by assigning a separate scheduling algorithm to each queue. For instance, the background queue may employ first-come-first-serve scheduling to maximize the usage of system resources for longer-running activities, while the foreground queue might use Round Robin scheduling to prioritize ...

Introduction MLFQ Programming is an instance of CPU scheduling technique that works through preserving several queues based on priority, each with a distinct time quantum. The delay period of those with greater importance queues is shorter, whereas the duration period of the ones with lower importance holds is longer. When a fresh procedure emerges, it is assigned to the top of the importance queue. The timer for the CPU chooses the most significant operation from the most important queue and allocates the processing power to it. The procedure is permitted to continue for a set amount of time or ... Read More

Introduction A system with more than one user (OS) is an operating system for computers that enables several individuals to communicate via the computer's infrastructure at the same time. Multiple users may utilize one machine or system of computers at the same time in an operating system designed for multiple users, alongside every individual getting a separate account while being able to carry out duties of their own. Multi-user systems of operation are frequently employed in circumstances in which multiple users must share identical materials or information and where interaction and cooperation are essential. Systems like these serve a purpose ... Read More

Introduction MS-DOS (which stands for Microsoft Disc Operating Systems) is a Microsoft developed OS. This came out initially in 1981 and quickly became the preferred OS over IBM-compatible desktop computers in the decades that followed. Microsoft's DOS is an interface for the command line (CLI) OS, which means it lacks the visual user interface (GUI) found in modern OSes like Microsoft Windows or Mac OS. Clients communicate with the OS instead by entering instructions into an administrative prompt MS-DOS was intended to serve as a simple and efficient computer operating system capable of running on cheap-powered hardware. It included basic ... Read More
