Operating System Definition
An operating system (OS) is a fundamental software that manages and controls the hardware and software resources of a computer system. It acts as an interface between the user and the computer, providing essential services and functionalities that enable users to interact with the system and run applications.
An operating system is a type of software that manages computer hardware and software resources. It provides common services for computer programs. In an iot based system for remote patient monitoring , the operating system is responsible for managing the sensors, actuators, and other hardware components.
It also provides the software platform for the applications that run on the system.
Purpose and Functions of an Operating System
- Resource Management: Manages hardware resources such as memory, CPU, storage, and input/output devices.
- Process Management: Creates and manages processes, which are instances of running programs.
- File Management: Manages the storage and retrieval of data on storage devices.
- Security: Protects the system from unauthorized access, viruses, and other threats.
- User Interface: Provides a way for users to interact with the system, typically through a graphical user interface (GUI) or command line interface (CLI).
Operating System Components
Essential Components
- Kernel: The core component that manages the system’s resources and provides basic services.
- Shell: A command-line interface or GUI that allows users to interact with the kernel.
- Device Drivers: Software that enables the system to communicate with hardware devices.
- File System: Manages the storage and organization of files on storage devices.
- Memory Manager: Allocates and manages memory resources for processes.
Interactions
- The kernel interacts with all other components, allocating resources and providing services.
- The shell provides a user interface to the kernel, allowing users to execute commands and manage processes.
- Device drivers communicate with hardware devices on behalf of the kernel, enabling the system to interact with peripherals.
Operating System Types
Desktop Operating Systems
- Microsoft Windows: Widely used on personal computers, known for its user-friendly interface and compatibility with a vast range of software.
- macOS: Apple’s proprietary OS for its Mac computers, renowned for its stability, performance, and sleek design.
- Linux: A free and open-source OS known for its customizability, security, and wide range of distributions.
Mobile Operating Systems
- Android: Google’s open-source OS for smartphones and tablets, known for its large app ecosystem and customizable nature.
- iOS: Apple’s proprietary OS for iPhones and iPads, known for its user-friendliness, performance, and exclusive app store.
Operating System Functions: An Operating System Is A Type Of
Process Management
- Creating and terminating processes.
- Scheduling processes to run on the CPU.
- Managing process memory and resources.
Memory Management, An operating system is a type of
- Allocating memory to processes.
- Managing virtual memory to extend physical memory.
- Protecting memory from unauthorized access.
File Management
- Storing and retrieving files on storage devices.
- Managing file permissions and access control.
- Providing file search and retrieval mechanisms.
Operating System Design
Principles
- Modularity: Dividing the OS into independent modules for ease of development and maintenance.
- Concurrency: Allowing multiple processes to run simultaneously, maximizing system utilization.
- Security: Protecting the system from unauthorized access, viruses, and other threats.
Approaches
- Monolithic Kernel: A single, large kernel that performs all OS functions.
- Microkernel: A small kernel that handles only essential tasks, delegating other functions to user-level processes.
- Hybrid Kernel: A combination of monolithic and microkernel approaches, providing both performance and security benefits.
