What is a Race Condition In OS : A race condition in operating systems, often referred to as “race condition in OS,” occurs when a system attempts to execute two or more operations simultaneously, requiring a specific sequence for correct completion. This phenomenon, encapsulated in the term “Race Condition,” emerges when different processes or threads engage […]

What is Inter-process Communication (IPC)? Inter-Process Communication (IPC), or process communication in an operating system (OS), is a fundamental component. IPC, acting as an advanced system, ensures efficient communication between different processes running concurrently within the system. This optimization improves information exchange among processes, fostering real-time collaboration by notifying processes of specific events. The primary purpose of

Within a program, A “Thread” is like a ‘Mini-Worker’ within a program, capable of doing tasks independently. Threads are ‘Lightweight Processes‘ and share the same resources, like memory and files, with their parent program, which is super efficient. Example: Imagine you’re writing a document in a word processing program. You decide to print it as

Process management in OS refers to the essential task of overseeing and controlling the execution of processes in an operating system. It involves creating, scheduling, and terminating processes to ensure efficient resource utilization and multitasking. In the past, single-user operating systems were the norm. However, in today’s computer systems, we have multitasking or multi-user systems.
Directory Structure in OS (Operating System) Directory Structure Overview: The root directory, often referred to as the root folder, represents the top-level directory on a disk drive. Essentially, a directory serves as a container for files, and it can contain multiple subdirectories, often referred to as subfolders. Within a directory, information about files and their

The file system is perhaps the most visible and most important component or part of an operating system. Whenever you interact with your computer, Actually you’re engaging with files and directories. Files are the fundamental building blocks of system storage; you might need to create a file for even a single character. From a system security

In today’s computing world, when it comes to booting up desktop and laptop computers, there are essentially two methods: the traditional BIOS-MBR approach and the newer UEFI-GPT method. Older devices typically stick with the former (BIOS-MBR), while more modern PCs, laptops, and tablets opt for the latter (UEFI-GPT). This method is fully compatible with the latest versions of Microsoft Windows, Linux, and Apple macOS.
This blog post will provide you with an insightful overview of how conventional BIOS-based PCs kickstart the process of loading an operating system. We’ll explore the fundamentals, including BIOS, MBR, and the essential boot sectors. So, let’s dive right in!

It is a small software program that is permanently stored in a ‘Read-only Memory’ (ROM) chip. ROM chips are Non-Volatile in nature and do not require a power supply to retain or hold data, unlike RAM memory chips, which need continuous power.
Firmware, often referred to as “software for hardware,” is a type of microcode or program embedded into hardware devices to help them operate effectively and ensuring their efficient operation. Devices like cameras, mobile phones, network cards, optical drives, printers, routers, scanners, and television remotes depend on firmware stored within their memory to operate seamlessly.
