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.
