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 Concurrency processing is the ability of an operating system to execute multiple tasks simultaneously, allowing for efficient utilization of resources and improved performance. In today's computing environment, with the availability of multi-core CPUs and high-speed networking, concurrency processing has become increasingly important for operating systems to meet the demands of users. Definition of concurrency processing Concurrency processing, also known as concurrent processing, refers to the ability of an operating system to execute multiple tasks or processes simultaneously, allowing for efficient utilization of resources and improved performance. It involves the parallel execution of tasks, with the operating system managing and ... Read More

In digital systems, several types of storage devices are used to store data and information in digital form. DVD, stands for Digital Versatile Disk, is a type of optical storage device that uses laser technology to read/write data. Based on the nature, DVDs are classified into the following three main types − DVD ROM DVD-R DVD-RW Read this article to learn how the DVD-R format is different from DVD-RW. Let's start with some basics of DVD R and DVD RW. What is DVD-R? DVD-R stands for Digital Versatile Disk Recordable. DVD-R is a type of DVD which is ... Read More

In computers and any other computing device, the processor is the most significant component of the system as it performs the most crucial task, i.e. processing. These days, we have several types of processors such as single core processor, dual core processor, quad processors, hexa core processor, octa core processor, etc. To understand the meaning of “core” in processor, consider the example of a highway with heavy traffic. If the highway have only one-way mode, then all the vehicles should pass one by one in a queue. Therefore, the taken to reach the destination by a vehicle will be more. ... Read More
