Operating Systems
An operating system (OS) is the primary system software that manages computer hardware and software resources. It acts as an essential intermediary between the user, applications, and physical components like the CPU and memory. Core functions include resource allocation, task scheduling, file management, and security.
Major Operating Systems
- Desktop & Laptop: Microsoft Windows dominates general-purpose computing, while Apple's macOS is popular for its integration into the Apple ecosystem. Linux is a widely used open-source OS prevalent in servers and programming.
- Mobile Devices: Google's Android is the most widely used mobile OS globally, whereas Apple's iOS powers iPhones and iPads.
- Servers & Enterprise: Unix and various Linux distributions handle massive workloads and cloud computing networks.
- The Kernel: The core of the OS that resides in memory, directly interacting with the hardware to manage tasks, memory, and devices.
- The Shell/UI: The user-OS interface, which can be a graphical user interface (GUI) or a command-line interface (CLI).
