Multiple processes that are running on various machines or nodes and interacting with one another to accomplish a single objective makeup distributed systems. In these systems, it's crucial to make sure that only one process is able to utilize a shared resource at once to prevent conflicts and data inconsistencies. One way to make sure that only one function is using a shared resource at once is through the use of mutual exclusion and Lamport's Algorithm is one of many accessible mutual exclusion algorithms. Lamportís Algorithm A centralized mutual exclusion algorithm called Lamport's Algorithm employs timestamps to determine the sequence ... Read More
A synchronization method called Lamport's Bakery method addresses the critical section issue in parallel computing systems. When more than one process needs to utilize a shared resource at once but only one process can do so, this is known as the critical section problem. To avoid conflicts and guarantee the accuracy of the system, the challenge is to make sure that each process uses the resource in a way that is mutually exclusive. Pseudo code for Lamport's Bakery Algorithm Here the Pseudo code for Lamport’s Bakery Algorithm − Initialize an array, called choosing, of size N, where N is ... Read More
Nowadays, the animation is the most powerful feature in the applications to attract more users, and it increases users' interest in exploring the application. In web applications, we can create animations using HTML and CSS. However, we can create animations using JavaScript, but it makes the website slower. In this tutorial, we will learn to load text animation using HTML and CSS. It is important to show loading text with animation while fetching data from API or loading web pages to make it more attractive. Example 1 In the example below, we created the ‘loader’ div and ‘loader-inner’ div element ... Read More
In JavaScript, every object has its own properties, and each object contains the prototype property. The string is also an object in JavaScript. So, it also contains the prototype property. The prototype property is nested in the object, meaning every prototype property contains another prototype property. The string object’s prototype property contains the default methods and properties. However, developers can customize the prototype property and add methods and properties to the string prototype. In this tutorial, we will learn to use the methods of string prototype property and customize them. Syntax Users can follow the syntax below to add any ... 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
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. ...

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
KaiOS is a mobile operating system that is designed to run on low-powered phones and IoT devices. It offers a middle ground between traditional flip phones and full-fledged smartphones, supporting features like 4G LTE, GPS, and Wi-Fi. Originally based on Firefox OS, KaiOS is now web-based and offers users a few extra apps beyond calling and texting, making it a good option for those who want more than a basic phone but don't need all the features of a smartphone. Developing for KaiOS To develop an app for KaiOS, you will need to use web technologies such as HTML, ... Read More
Registered Jack The Registered jack is a network interface to connect various data equipment and telecommunication systems to provide the services offered by the telephone exchange. The local channels then exchange data for the shorter or longer-distance carriers. It offers network cabling, fixing wires, and jack construction. Customers and telephone companies have to register through the registration interface to deliver and manage the physical installation of jacks and wires this was made mandatory in the year 1970 by Federal Communications Commission (FCC) and registered connections have brought to real-time usage in the year 1973 with the physical setup of wires, ...
