Linux is a free and open-source Unix-like operating system kernel that serves as the core component of a Linux operating system (OS).

The Linux kernel is a crucial part of the operating system, managing hardware resources and providing essential services.

When Linux Invented?

Linux was created by Linus Torvalds, a Finnish computer science student, in 1991.

Linus started working on the project as a hobby, developing the initial version of the Linux kernel and releasing it to the public. The kernel’s release marked the beginning of what would become the Linux operating system.

Where Linux is used most?

Linux is used in various environments and has gained popularity across different sectors.

Some of the primary areas where Linux is used most include:

  • Servers
  • Data Centers
  • Cloud Computing
  • Supercomputers
  • Networking Equipment
  • Mobile Devices
  • Embedded Systems
  • Development Environments
  • Education
  • Desktop Computing

The versatility, stability, and cost-effectiveness of Linux contribute to its widespread adoption in various industries and applications.

Which Linux Best?

The choice of the “best” Linux distribution (often called a distro) depends on your specific needs, preferences, and the use case.

Different Linux distributions cater to different audiences, and what may be best for one person or situation might not be ideal for another.

Here are some popular Linux distributions, each with its strengths and characteristics:

  • Ubuntu
  • Debian
  • Fedora
