Study Notes
Operating System Types
-
Batch OS: Executes jobs in batches without user interaction. Early systems like IBM's OS/360 are examples. Suitable for large, sequential tasks. No user interaction during processing.
-
Time-Sharing OS: Allows multiple users to interact with the system simultaneously through time slicing. Examples include UNIX, Linux, and Multics. Enables concurrent user interaction through time allocation to each user. Used for interactive tasks like servers and workstations.
-
Real-Time OS (RTOS): Designed for processing and response within specific time constraints. Examples include VxWorks, RTEMS, and FreeRTOS. Used in systems requiring immediate or timely responses, like automotive, medical devices, and industrial control. Two types: hard (guaranteed) and soft (acceptable) real-time.
-
Distributed OS: Manages multiple interconnected computers as a single system. Google's Android (in some contexts) and Plan 9 are examples. Supports seamless resource sharing across a network. Emphasizes transparency, fault tolerance, and load balancing. Used in large-scale systems.
-
Network OS: Manages network resources, enabling communication and file sharing. Examples include Novell NetWare and Microsoft Windows Server. Handles network functionalities like communication, security, and centralized resource management. Often used on servers to manage user accounts and permissions.
-
Embedded OS: Optimized for specific, resource-constrained hardware in embedded devices. Examples include Android (for mobile devices) and iOS. Examples of embedded use include appliances, automobiles, medical devices, and other specialized equipment. Known for small size and low resource requirements.
-
Single-User OS: Designed for a single user, though may allow multitasking. Examples include Windows, macOS, and Linux (for individual devices). Supports a single user and multitasking capabilities.
-
Multi-User OS: Designed for multiple users to access and utilize system resources concurrently. UNIX, Linux, and Windows Server are examples. Supports concurrent access and independent user accounts, usually found in mainframes or large servers.
-
Multitasking OS: Enables multiple tasks or processes to run simultaneously. Windows, Linux, and macOS are examples. Features time-sharing and resource management for concurrent execution of applications. Common in modern OSes.
-
Monolithic Kernel OS: The entire OS (kernel, drivers, file management) runs within a single memory space. Linux and traditional UNIX are examples. Tightly integrated components, potentially faster but more complex development.
-
Microkernel OS: Most services (drivers, file systems, networking) run outside the kernel in user space. Minix, QNX, and Mach are examples. Increased modularity, fault isolation, and flexibility, but potential performance trade-offs, compared to monolithic kernels.
-
Hybrid OS: Combines elements of both monolithic and microkernel architectures. macOS and Windows NT are examples. Leverages benefits of each for a customized balance of security, efficiency, and flexibility.
-
Client-Server OS: Supports a network with servers providing services to clients. Windows Server and Linux with Apache Web servers are examples. Centralized server-based services (like data storage or applications) accessed by client computers.
-
Cloud-Based OS: Operates on virtualized cloud resources, providing access via the internet. Chrome OS and cloud platforms like AWS and Azure are example systems. Access to applications and files remotely without dependence on local hardware. Usually for lightweight devices.
