Types of Operating Systems:
Single-User Operating Systems:
These OS are designed for a single user to perform tasks on a personal computer. Examples include Microsoft Windows and macOS.
Multi-User Operating Systems:
Multi-user OS support multiple users simultaneously, allowing them to access the system resources concurrently. Unix and Linux are prominent examples.
Real-Time Operating Systems:
Real-time OS prioritize tasks based on their urgency, ensuring timely execution. They are crucial for applications requiring precise timing, such as industrial automation and aerospace systems.
Network Operating Systems:
Network OS facilitate communication and resource sharing among multiple computers over a network. Examples include Windows Server and Linux Network Operating System (NOS).
Mobile Operating Systems:
Mobile OS are tailored for smartphones and tablets, providing features like touch screen interface, app ecosystem, and power management. Android and iOS dominate the mobile OS market.
Operating System Components:
Kernel:
The kernel is the core component of an OS, responsible for managing system resources and providing essential services.
User Interface:
UI allows users to interact with the computer through graphical elements like windows, icons, menus, and buttons.
File System:
The file system organizes and stores data on storage devices, enabling users to create, modify, and access files.
Device Drivers:
Device drivers facilitate communication between the OS and hardware devices, ensuring proper functioning of peripherals like printers, scanners, and graphics cards.
Memory Management:
Memory management involves allocating and deallocating memory space for processes, optimizing system performance and preventing memory leaks.
Process Management:
Process management oversees the execution of processes, scheduling tasks, and allocating resources to ensure smooth operation.
Security and Protection:
OS implement security measures like user authentication, encryption, and access control to safeguard against unauthorized access and malware threats.
Networking:
Networking features enable computers to connect and communicate with each other over local area networks (LANs) or the internet.
Application Support:
OS provide libraries and APIs for developers to create and run applications, facilitating software development and compatibility.
