Study Notes

Operating System Overview

The primary purpose of an operating system is to manage computer hardware and provide common services to computer programs.

Design and Organization

Defining the goals of an operating system before design begins is crucial to ensure the system meets its intended purpose.
Operating systems are organized internally into several components, including process management, memory management, file management, and I/O management.

Characteristics and Functions

A key characteristic of a new operating system design is its ability to manage computer hardware and provide common services to computer programs.
An operating system acts as an intermediary between the user of a computer and the computer hardware, managing hardware resources and providing services to application programs.
The primary function of an operating system is to manage computer hardware and provide common services to computer programs.

System Components

The hardware component of a computer system provides the basic computing resources.
Personal computer (PC) operating systems support a single user and provide a graphical user interface.
Mainframe operating systems support multiple users and provide a command-line interface.
Application programs use the services provided by the operating system to interact with the computer hardware.

Open-Source Operating Systems

The purpose of open-source operating systems is to provide a collaborative and community-driven approach to operating system development.

System Structure

The system structure consists of several components, including the hardware, operating system, and application programs, which interact to provide a functional computer system.
The chapter discusses the system structure, including the role of the operating system, application programs, and hardware components.

Key Objectives and Goals

One of the objectives of the chapter is to understand the role and functions of an operating system in a computer system.
