Study Notes
Definition of Operating System
- An operating system (OS) serves as an interface between the computer user and the hardware.
- It facilitates the execution of user programs and simplifies problem-solving for users.
Goals of Operating Systems
- Execute user programs efficiently.
- Enhance system convenience and usability.
- Optimize resource utilization within the hardware.
Components of a Computer System
- Hardware: Basic computing resources including CPU, memory, and I/O devices.
- Operating System: Manages and coordinates hardware usage across various applications and users.
- Application Programs: Designed for specific user tasks such as word processing, web browsing, or gaming.
- Users: Include individuals, machines, or other computers utilizing the system.
Different Perspectives of Operating Systems
- Users prioritize convenience, ease of use, and performance, often disregarding resource efficiency.
- In shared computing environments (mainframes, minicomputers), an OS is crucial for balancing multiple users' needs.
- A dedicated system (workstation) may have dedicated resources but often accesses shared server resources.
- Mobile devices are designed with limited resources, focusing on user experience and battery life (e.g., touch screens, voice recognition).
- Some systems, like embedded computers, function autonomously without user interaction, particularly in appliances or vehicles.
Diverse Applications of Operating Systems
- Operating systems are utilized in various devices, from common household appliances (like toasters) to complex systems (like spacecraft and industrial controls).
- The range of OS designs reflects their adaptability to different functionalities and environments.
