What is the Operation System?
An operating system (OS) is a crucial software that manages computer hardware and software resources and provides common services for computer programs. It acts as an intermediary between users and the computer hardware.
Operating System is a Software program which used to preform task by computer.
Or
An operating system is a software program or a set of software programs that manages and controls the hardware and software resources of a computer.
It provides an interface for users and applications to interact with the computer's hardware and coordinates various tasks, such as process management, memory management, file system operations, and device management, to ensure the efficient and secure operation of the computer. Hence Operating System also called Resource Maneger.
Operating systems are fundamental to the functioning of computers and various digital devices, managing resources, providing user interfaces, and enabling application execution. The choice of an operating system depends on the specific requirements of the user or the application environment
Functions of an Operating System
1. Process Management:
Manages processes in the system, including process scheduling, creation, and termination.
Handles multitasking by ensuring that multiple processes can run concurrently without interfering with each other.
2. Memory Management:
Manages the computer’s memory, allocating space for processes and ensuring efficient memory usage.
Handles swapping between main memory and disk storage when the system runs out of RAM.
3. File System Management:
Manages files on various storage devices.
Provides functionalities like file creation, deletion, reading, writing, and access permissions.
4. Device Management:
Manages device communication via their respective drivers.
Handles input/output operations and provides a way for software to interact with hardware devices.
5. Security and Access Control:
Ensures system security through user authentication and authorization.
Protects data and resources from unauthorized access and potential threats.
6. User Interface:
Provides a user interface, which can be CommandLine Interface (CLI) or Graphical User Interface (GUI), for user interaction with the system.
How many Types of Operating Systems?
1. Batch Operating Systems:
Executes batches of jobs without user interaction.
Jobs are collected, grouped, and processed in batches.
Example: Early IBM mainframe operating systems.
2. TimeSharing Operating Systems:
Allows multiple users to use the system simultaneously by providing each user with a time slice.
Improves system utilization and responsiveness.
Example: UNIX.
3. Distributed Operating Systems:
Manages a group of independent computers and makes them appear as a single coherent system.
Ensures resource sharing and communication among networked systems.
Example: Amoeba, Plan 9.
4. RealTime Operating Systems (RTOS):
Provides immediate processing and response to input, typically used in embedded systems.
Guarantees certain capabilities within a specified time frame.
Example: VxWorks, RTLinux.
5. Embedded Operating Systems:
Designed for embedded systems which are part of a larger machine.
Highly specialized and optimized for specific hardware.
Example: Embedded Linux, QNX.
6. Network Operating Systems:
Provides functionalities for networking, enabling computers to communicate and share resources over a network.
Example: Windows Server, Novell NetWare.
7. Mobile Operating Systems:
Specifically designed for mobile devices such as smartphones and tablets.
Optimized for touchscreens and mobile hardware.
Example: Android, iOS.
8. Desktop Operating Systems:
Designed for personal computers used by individuals for general purpose tasks.
Example: Windows, macOS, Linux distributions like Ubuntu.
9. Server Operating Systems:
Optimized to provide services to other computers over a network.
Typically more robust, stable, and secure compared to desktop OS.
Example: Windows Server, Red Hat Enterprise Linux.
Give some Examples of Operating Systems.
1. Windows:
Developed by Microsoft, widely used in personal and enterprise environments.
Known for its GUI and extensive application support.
2. macOS:
Developed by Apple Inc. for their line of Macintosh computers.
Renowned for its sleek design, usability, and integration with Apple’s ecosystem.
3. Linux:
Opensource operating system, highly customizable.
Used in various environments, from desktops to servers to embedded systems.
Examples: Ubuntu, Fedora, Debian.
4. UNIX:
A powerful, multiuser OS originally developed in the 1970s.
Influenced many other operating systems and forms the basis of many modern OS like Linux and macOS.
5. Android:
Developed by Google, based on the Linux kernel.
Dominates the mobile OS market with a vast ecosystem of apps and devices.
6. iOS:
Developed by Apple Inc. for iPhone, iPad, and iPod Touch.
Known for its smooth performance, security, and integration with Apple’s hardware and services.
