Getting Started with Linux

Definition and Purpose

Linux distributions, or distros, are variations of the Linux operating system tailored to specific needs. Each distro combines the Linux kernel, software applications, libraries, and a package management system. They’re used for addressing diverse user requirements, spanning from desktop computing to server administration.

Enterprise-Class Distributions

Red Hat and CentOS

  • Red Hat is a leading enterprise Linux distribution with commercial support.
  • CentOS, derived from Red Hat, provides a free and open-source alternative with similar functionality.
  • Commands and configurations are almost identical between Red Hat and CentOS, making them interchangeable for most purposes.

Ubuntu and Debian

  • Ubuntu, known for its user-friendly interface, is widely used for desktop computing.
  • Debian, a stable foundation, serves as the basis for many distributions, including Ubuntu.
  • Commands and configurations are virtually the same between Ubuntu and Debian, allowing users to seamlessly transition between them.

Installation Methods

  • Live CD/USB: Allows running the OS from external media, providing an option for installation.
  • Graphical Installation: User-friendly interface suitable for desktop-oriented distributions.
  • Text-based Installation: Terminal-based installation is preferred for servers, common to both Red Hat/CentOS and Ubuntu/Debian.
  • Network Installation: Installs the OS from the internet or a local network, applicable to both categories.

Basic System Requirements

  • Processor: Linux supports a wide range of processors, suitable for both older models and modern multi-core CPUs. The minimum requirement is sufficient for basic functionality, and the maximum range accommodates advanced configurations.
  • Memory (RAM): Recommendations for smooth performance typically start at a minimum of 1GB or more. The maximum range varies, supporting a broad spectrum of RAM configurations to meet diverse computing needs.
  • Disk Space: Minimum space requirements are generally interchangeable, with around 20GB recommended for installations. The maximum range depends on specific distribution needs but allows for larger disk space as required.
  • Graphics and Display: Compatible with a broad spectrum of graphics cards and displays, ensuring functionality even with basic hardware. The adaptability extends to high-end graphics configurations for more demanding graphical environments.
  • Network Connectivity: Basic internet connectivity is recommended for updates and software installations. The distributions support various network configurations, offering versatility for different networking needs in a range of use cases.
