An operating system is system software that manages computer hardware and software resources and provides common services for computer programs. It acts as an interface between the user and the computer hardware.
Windows and Linux (or macOS, Android, iOS)
The first version of iOS was released in 2007.
Multitasking is the ability of an operating system to run multiple applications or processes simultaneously, allowing users to switch between different tasks efficiently.
A real-time operating system (RTOS) is an operating system designed to process data and events within specific time constraints. It guarantees response within strict time deadlines, making it suitable for time-critical applications.
Time-sharing operating system allows multiple users to share computer resources simultaneously by rapidly switching between users. Distributed operating system manages a group of independent computers and makes them appear as a single coherent system, distributing processing and resources across multiple machines.
Process Management: The operating system manages the execution of processes, allocating CPU time, creating and deleting processes, and handling process synchronization and communication. It ensures efficient utilization of the processor and fair allocation of resources among competing processes.
Memory Management: The OS manages the computer's primary memory, allocating and deallocating memory space as needed by programs. It keeps track of which parts of memory are being used and by whom, and handles memory swapping between main memory and disk when required.
Android: Developed by Google, Android is an open-source, Linux-based operating system designed primarily for touchscreen mobile devices. It features a customizable user interface, supports a wide range of applications through Google Play Store, and is used by various manufacturers like Samsung, Xiaomi, and OnePlus.
iOS: Developed by Apple Inc., iOS is a proprietary mobile operating system exclusively for Apple devices like iPhone and iPad. It is known for its security, smooth user experience, tight integration with Apple's ecosystem, and curated App Store with strict quality controls.
Windows is a series of graphical operating systems developed, marketed, and sold by Microsoft. First released in 1985 as Windows 1.0, it has evolved through various versions including Windows 95, Windows XP, Windows 7, Windows 8, and Windows 10/11. Windows introduced the graphical user interface (GUI) to mainstream computing, making computers more accessible to non-technical users. It dominates the personal computer market with approximately 75% market share. Key features include the Start menu, taskbar, File Explorer, and support for a vast library of software applications. Windows supports both consumer and enterprise environments with different editions tailored to various needs.
Apple has developed several operating systems for its hardware products:
macOS: Apple's desktop operating system for Mac computers, known for its stability, security, and elegant user interface. It features the Dock, Spotlight search, and tight integration with other Apple devices.
iOS: The mobile operating system for iPhone and iPad, featuring a touch-based interface, App Store, and strong security features.
iPadOS: A variant of iOS specifically optimized for iPad tablets with enhanced multitasking capabilities.
watchOS: The operating system for Apple Watch, focusing on health monitoring and quick interactions.
tvOS: The operating system for Apple TV, designed for media consumption and entertainment.
All Apple operating systems are known for their tight hardware-software integration, security features, and seamless ecosystem connectivity.

An interactive operating system is designed for direct user interaction, where users can provide input and receive immediate responses from the system. These systems support real-time interaction through graphical user interfaces (GUIs) or command-line interfaces (CLIs).
Interactive operating systems are used in:
These systems prioritize user responsiveness and ease of use, allowing direct manipulation of applications and immediate feedback to user actions.
Organization and Structure: Directories should be logically organized with a clear hierarchical structure that makes it easy to locate files. This includes using meaningful folder names, categorizing files appropriately, and maintaining consistent naming conventions. A well-organized directory structure improves efficiency and reduces the time needed to find specific files.
Access Control and Security: Proper permissions and access controls must be implemented to ensure that only authorized users can access, modify, or delete files and directories. This includes setting appropriate read, write, and execute permissions for different user groups, implementing authentication mechanisms, and regularly reviewing access privileges to maintain data security and integrity.
