Introduction A distributed operating system is a type of operating system designed to manage the resources of a network of computers and devices, rather than a single computer. In such a system, the file model plays a crucial role in managing files and providing access to them across the network. The file model defines how files are created, stored, accessed, and managed in a distributed environment. It involves concepts such as file systems, distributed file systems, data consistency, fault tolerance, and security. In this topic, we will explore the basic concepts of the file model in distributed operating systems, the ... Read More

The File Allocation Table (FAT) is a critical component of computer systems that allows for the organization and management of files on a disk. It is an essential part of the file system that helps to keep track of where files are stored on a disk and how much space is available for new files. FAT has been around for many years and has evolved over time, with different versions developed to suit the needs of different operating systems and disk formats. Understanding how FAT works and its advantages and disadvantages can help computer users make informed decisions about managing ... Read More

The most basic difference between hardware and computer platform is that the hardware is the physical components of a computer system that can be seen, touched, and manipulate, whereas a computer platform is a fundamental hardware and software infrastructure which supports the operation of computer applications. Read this article to learn more about hardware and computer platform, and the important differences between them. What is Hardware? The term "hardware" represents the physical components of a computer system that we can see and touch. For example, motherboard, CPU, memory devices, power supply, sound card, mouse, keyboard, etc. are the hardware of ... Read More

A computer is a general purpose electronic device that is used to perform a wide range of computing tasks, whereas an embedded system is a specialized computer that is used to perform one or more specific functions. Read this article to learn how a computer is different from an embedded system. What is a Computer? A computer is an electronic machine that is designed to accomplish a wide range of computing tasks. Hence, a computer is basically a versatile electronic device that can be utilized for a variety of applications from general word processing and web browsing to complex ... Read More

Both CD-R and CD-RW are types of optical storage devices. A CD-R (Compact Disk- Recordable) is a write-once read-many device, which means data can be written to it only once but can be read many times. In contrast, a CD-RW (Compact Disk-Rewritable) is a CD that allows data to be written multiple times. Read this article to learn more about CD-R and CD-RW and how they are different from each other. What is CD-R? CD-R stands for Compact Disk-Recordable. CD-R is a type of optical storage disk that is used for storage of digital data. It is a type ... Read More

In a computer system, power supply or power supply unit is a hardware component that supplies required electrical power to other components of the computer system. The power supply unit converts a 220 V AC (Alternating Current) supply into a low voltage DC (Direct Current) supply. The major function that a computer power supply unit performs are − Rectification − Conversion of alternating current supply into direct current supply. Voltage transformation − Decreases the high AC voltage into low voltages. Voltage regulation − Regulates the output voltage to make it constant even when the input voltage is fluctuating. ...

In a computer system, motherboard is a crucial part of the system. This is because, the complete electronic circuit of the computer system is designed on it. Motherboard includes several electronic circuits and slots for connecting various system components like RAM, HDD, CPU, etc. At present, there are several types of motherboards available in market. In this article, we will discuss the two important types of motherboards namely, AT motherboard and ATX motherboard, and the important differences between them. So, let us start with a basic introduction of AT and ATX motherboard. What is AT Motherboard? AT Motherboard stands ... Read More

Introduction Deadlock prevention is a technique used in computer science to avoid situations where multiple processes or threads are blocked and unable to proceed because they are waiting for each other to release resources that they need to complete their tasks. Deadlocks can be detrimental to the performance of a system and can cause significant delays in completing tasks. To prevent deadlocks, various techniques such as resource allocation graph, preemptive scheduling, and detection and recovery are used. Each of these techniques helps in ensuring that resources are used efficiently and prevent situations where a deadlock may occur, thereby ensuring optimal ... Read More

Introduction Deadlock ignorance in operating systems occurs when potential deadlocks are overlooked or not appropriately managed. It is a significant issue as deadlocks can cause system crashes, data loss, and decreased performance, leading to lost productivity and reduced profitability. Deadlock ignorance can result from various factors, including system complexity, lack of awareness or education, and organizational priorities. It is important for system administrators and developers to understand the potential sources of deadlock and implement appropriate mechanisms for managing it. Failure to do so can have severe consequences for operating systems and the organizations that rely on them. Definition of deadlock ... Read More

In complex systems involving multiple processes and shared resources, the potential for deadlocks arises when processes wait for each other to release resources, causing a standstill. The resulting deadlocks can cause severe issues in computer systems, such as performance degradation and even system crashes. To prevent such problems, the technique of deadlock avoidance is employed. It entails scrutinizing the requests made by processes for resources and evaluating the available resources to determine if the grant of such requests would lead to a deadlock. In cases where granting a request would result in a deadlock, the system denies the request. Deadlock ... Read More
