Study Notes
Operating Systems Overview
- Operating systems (OS) are software that control hardware and software components on a computing device.
- OS manages hardware and software components.
- OS schedules programs and provides services to users or programs.
- OS is commonly abbreviated as OS.
Exam Objectives
- 1.1 Linux Evolution and Popular Operating Systems: Knowledge of Linux development and major distributions is required.
- 4.1 Choosing an Operating System: Understanding major operating systems and Linux distributions is necessary.
Decision Points
- Role: Is the OS used for a desktop (one user) or server (many users)?
- Function: Does the system need specific software? What are the user's skills?
- Life Cycle: What is the service lifetime, release cycles, and maintenance cycles for support and updates?
- Stability: Are OS releases beta (not tested) or stable (tested)?
- Compatibility: Is the OS backwards compatible with existing software?
- Cost: A significant factor for new systems. Microsoft has annual license fees. Apple does not charge fees but only works on Apple hardware. Multiple Linux providers offer enterprise support, but support is not always free.
Popular Operating Systems
- Microsoft Windows: Offers desktop and server versions, slow release cycle (3-5 years), emphasis on backward compatibility, runs a Graphic User Interface (GUI). Improved scripting and management are developed to compete with Linux.
- Apple macOS: Runs only on Apple hardware, server version adds packages for management and sharing, UNIX certified, new major releases every 18-24 months.
- Linux: A family of operating systems and not a single OS. Distributions are chosen after selecting Linux to fit the use case, such as desktop, server, scientific, or network. Some distributions offer commercial support while others are volunteer based. Different distributions have varying update cycles (major and minor), some having LTS (long-term support) releases. Distributions are zero cost.
- Android: A mobile platform that lacks traditional GNU/Linux packages to be compatible with desktop. Supported by Google.
- Other Linux Distributions: Include Raspbian (Raspberry Pi), Linux From Scratch (LFS). LFS consists of an online book, source code, and instructions to build a custom Linux distribution.
Linux Distributions
- Red Hat: Focuses on server applications like web and file serving. Releases Red Hat Enterprise Linux (RHEL) a stable distribution with long release cycles; sponsors Fedora project (personal desktop with latest software). CentOS is a free version of RHEL software without support. Scientific Linux is based on Red Hat, designed for specific use cases.
- SUSE: One of the first Linux distributions, originated from Slackware, contains proprietary code and is often sold as a server product. An open source version OpenSUSE exists with desktop packages.
- Debian: Promotes open-source software, has its own packaging system (apt) based on .deb files. Ubuntu is the most popular Debian distribution. Has variants for desktop, server, and other uses. Linux Mint is derivative of Ubuntu, with various versions and licensing restrictions.
