Study Notes

What is an Operating System?

An operating system is a program that bridges the gap between the user and the computer hardware.
It's designed to provide a user-friendly environment for executing programs.
Primary goal: Make the computer system easy to use.
Secondary goal: Optimize the use of computer hardware efficiently.

Components of an Operating System

Peopleware: Refers to individuals who interact with the data processing environment.
Hardware: Consists of the physical electronic devices and tangible components of the computer system.
Software: Includes programs and instructions that empower the computer system to function effectively. This encompasses programming languages, application programs, and the operating system itself.

Functions of Operating Systems

Broad Functions:
- Resource Sharing: Resolves conflicts when multiple users or programs need to access the same resources.
- Performance Optimization: Aims to maximize the use of system resources for optimal performance.
- Simplified Usage: Makes using the computer system easier for users.
- User-Computer Interface: Acts as a communication bridge between the user and the computer.
- Resource Accounting: Tracks how resources (like memory, CPU time, etc.) are being used.
Specific Functions:
- Job Sequencing: Determines the order in which tasks are executed.
- Interrupt Handling: Manages external events or requests (like user inputs) that interrupt ongoing processes.

Introduction to Operating Systems

An operating system (OS) is a program that acts as an intermediary between a computer user and the computer hardware.
Its primary purpose is to create an environment where users can execute programs efficiently.
The OS aims to make the computer system easy to use while optimizing hardware utilization.

Components of Operating Systems

Peopleware: Individuals involved in operating data processing.
Hardware: The physical electronic devices and structure that constitute the computer system.
Software: Programs and instructions that enable the computer to function effectively, including programming languages, application programs, and the operating system itself.

Functions of Operating Systems

Broad Functions
- Resolves conflicts when resources are shared.
- Optimizes performance by maximizing utilization.
- Simplifies the use of the computer system.
- Acts as an intermediary between user and the computer.
- Tracks and accounts for resource usage.
Specific Functions
- Job Sequencing: Selects the next group of processes for a lengthy job to be executed.
- Interrupt Handling: Manages and handles interruptions received by the system.
