Study Notes
Module 02: Operating Systems
- Module 2 covers Operating Systems.
- Exam objective 1.1 focuses on Linux Evolution and popular operating systems.
- Exam objective 4.1 focuses on choosing an operating system.
- Knowledge of Linux development and major distributions is important.
- Users have choices between three major operating systems: Microsoft Windows, Apple macOS, and Linux.
- Microsoft Windows is based on proprietary code that is not Unix or Linux based.
- Key factors to consider when choosing an operating system include: role, function, life cycle, stability, compatibility, and cost.
Operating System
- Software that manages the hardware and software components on a computing device.
- Schedules programs and provides services to users and programs (e.g., printing).
- Commonly abbreviated as OS.
- There is a software layer that sits between the user and the hardware that is the operating system.
Decision Points
- Role: Is it accessed by one user (desktop) or many users remotely (server)?
- Function: Does it need to run specific software and what are the user skills?
- Life Cycle: Service lifetime, release cycles, and maintenance cycles for support and updates vary by OS type.
- Stability: Are OS releases beta (not tested) or stable (tested)?
- Compatibility: Is it backwards compatible with software made for earlier versions?
- Cost: An important factor for new systems. Microsoft has annual license fees. Apple does not charge annual fees, but is only used for Apple hardware. Multiple Linux providers offer enterprise support, but even though the software is free support is not.
Microsoft Windows
- Offers desktop and server versions.
- Slow release cycle (3–5 years), long maintenance cycle.
- Emphasis on backward compatibility.
- Uses a Graphical User Interface (GUI).
- Scripting and management abilities are developed to compete with Linux.
Apple macOS
- Runs only on Apple hardware.
- Server version adds packages to the desktop version to assist in management and sharing.
- Certified as UNIX.
- Releases new major versions every 18–24 months.
Linux
- Unique as users must select a distribution after choosing Linux.
- Different distributions focus on different uses (e.g., desktop, server, scientific, network).
- Some distributions offer commercial support, while most are volunteer-based.
- Not UNIX certified, but similar.
Linux Distributions
- Red Hat: Focuses on server applications (web, file serving). Red Hat Enterprise Linux (RHEL) is a stable distribution with long release cycles. Sponsors Fedora Project (personal desktop, latest software) and CentOS (free version of RHEL software without support.)
- SUSE: One of the first distributions, derived from Slackware, and sold as a server product. Has a workstation version. OpenSUSE is a completely open, free version with multiple desktop packages.
- Debian: Promotes open-source software. Invented its own package management system (apt) based on the .deb file format. Ubuntu is a popular Debian distribution with desktop, server, and application variants. Offers LTS versions. Linux Mint is a derivative of Ubuntu with various free versions, some with license restrictions.
Android
- Platform for mobile users.
- Lacks traditional GNU/Linux packages to be compatible with desktops.
- Sponsored by Google.
Other Linux Distributions
- Raspbian: Designed to run on Raspberry Pi hardware.
- Linux From Scratch (LFS): Online book, source code, and instructions for creating custom Linux distributions. Can be used as a learning tool.
