Efficiently allocates CPU time, memory, storage, and other hardware resources to applications, preventing conflicts and maximizing performance.
Implements authentication, authorization, and encryption mechanisms to safeguard data and prevent unauthorized access to system resources.
Provides intuitive graphical or command-line interfaces that allow users to interact with applications and manage system settings with ease.
Organizes and maintains data storage, enabling efficient file creation, access, modification, and deletion while ensuring data integrity.
Controls the creation, scheduling, and termination of processes, allowing multiple applications to run concurrently on a single system.
Facilitates communication between hardware devices and applications through standardized interfaces, enabling hardware compatibility.
From simple batch processing systems to complex distributed environments, operating systems have evolved dramatically over the decades.
Early computers operated without dedicated operating systems. Programs were executed directly on hardware, requiring manual operation and resulting in significant idle time.
Introduction of batch processing systems that automated program execution sequences, improving efficiency by reducing setup time between jobs.
Multiprogramming and time-sharing systems emerged, allowing multiple users to interact with a single computer simultaneously and introducing the concept of interactive computing.
Personal computers popularized graphical user interfaces, while networks and distributed systems connected computers globally, leading to client-server architectures.
Cloud-native operating systems, containerization, microservices architecture, and AI-enhanced systems represent the cutting edge of operating system development.
Different computing environments require specialized operating systems
