Portable – Portable here means software supports different types of hardware Linux kernel and application programs support installation on any kind of hardware platform.

  • Open Source – Linux source code is freely available and is a community-based development project. Multiple teams work on Linux continuously to enhance and evolve Linux’s capability.
  • Multi-User – System resources like memory/ram/application programs can access multiple users simultaneously.
  • Multiprogramming – Multiple applications can be run simultaneously at one time.
  • Hierarchical File System – Yes supports standard file structure, where system files/user files are arranged in a hierarchical way.
