Study Notes
Introduction to Unix
- An operating system (OS) is a program that starts when a computer is turned on and runs underneath all other programs.
- An OS is software that manages a computer system's hardware and software resources, providing a simple virtual machine for users.
- Operating systems can be categorized as single-user single-process, single-user multi-process, and multiuser multi-process.
Tasks of an Operating System
- Control hardware
- Run applications
- Manage data and files securely
Operating System Characteristics
- Separates hardware management from applications/programs
- Allows applications to work across different hardware platforms
- The kernel is the core function of the OS, handling basic-level communication between processes and hardware
- Libraries provide standardized access to kernel functions
Examples of Operating Systems
- DOS
- Windows
- Ubuntu
- Linux
- Mac
- Android
History of Unix
- Developed in the 1970s as a research project at Bell Laboratories
- Initially developed as versions 1-6, with characteristics:
- Written in C, with a small subset of code tailored to a target processor
- Released as C source code, allowing modification and improvement
- Designed to allow users to run multiple processes concurrently and connect them with IPC channels
What is Unix?
- An operating system that is mostly command-based
- Distributed under an open-source license
- Provides a hierarchical file structure for easier access and maintenance of data
- Foundation of modern Linux and BSD operating systems
- Capable of handling multiple user activities simultaneously
Unix Architecture
- Comprised of three parts: kernel, shell, and other programs
- Kernel is the heart of the Unix operating system, allocating system resources and coordinating computer internals
- Shell is a program that processes user requests, interpreting commands and calling programs
- Application programs provide additional functionality
Unix Features
- Portable: works on different hardware platforms
- Open-source: source code is freely available and community-based
- Multi-user: allows multiple users to access system resources
- Multiprogramming: allows multiple applications to run simultaneously
- Hierarchical file system: provides a standard file structure
- Shell: provides a command-line interface for executing commands
- Security: provides user security using authentication features
- Excellent networking environment: provides programs and utilities for networked applications
Flavors/Versions of Unix
- Solaris Unix
- AIX
- HP Unix
- Linux
- BSD
Unix Distributions
- Fedora
- Ubuntu
- Linux Mint
- Debian
- CentOS
