  In today’s technology-driven world, understanding operating systems (OS) is crucial, especially for developers. An operating system acts as the backbone of any computing device, managing hardware and providing the necessary environment for applications to run. For developers, a solid understanding of OS fundamentals can significantly impact software performance and compatibility, making it an essential skill for anyone in software development. In this article, we’ll explore the fundamentals of operating systems, key OS concepts for developers, and a comparison of major operating systems—Linux, macOS, and Windows—to help developers make informed choices about their work environment. 1. What is an Operating System? An operating system (OS) is the foundational software that coordinates a computer's hardware and software. It functions as a bridge between hardware (like CPU, memory, and storage) and the applications we use. The OS is responsible for core tasks, from powering on the de...

  Peer-to-peer (P2P) technology is transforming the way digital services are delivered and consumed, relying on a decentralized architecture that distributes control across individual users rather than central authorities. In this article, we explore the wide-ranging applications of P2P systems, from file sharing and cryptocurrency to communication, decentralized applications, and beyond, while discussing the benefits and challenges each of these use cases presents. This first diagram shows the architectural difference between: Traditional client-server model (left): where all clients connect to a central server. P2P network (right): where all peers connect directly to each other. 1. File Sharing One of the earliest and most popular uses of P2P technology is in file sharing, with the BitTorrent protocol leading the way. BitTorrent revolutionizes file sharing by breaking large files into smaller pieces and distributing these pieces across a network of users. How It Works : When do...
