What Is Linux?

Linux is an operating system similar to Google Android, Microsoft Windows and Apple Mac Operating systems. Interaction between a computer hardware and software is enabled via an operating system. The operating system is what conveys the input to the processor and then delivers the results to the computer hardware. This is one of the main functions of an operating system.

Linux was introduced in the nineties and ever since then it was popularly used in laptops, phones, fridges, smart watches and many other devices.

The Evolution of Linux Operating systems

The brainchild behind Linux operating systems is Linus Torvalds. In 1991 he had an idea to improve the UNIX operating system. The changes he came up with were rejected by the developers and this was what prompted him to build an operating system that allows for users to make modifications. Thus, Linux came into being.

The Linux OS contains the following components listed below:

  • System Software
  • User Process
  • User Utility
  • Compilers
  • System Libraries
  • Kernel
  • Kernel modules


This is the key part of the Linux operating system. It allows for communication and interaction between the hardware and software. The Kernel has four main functions:

  • Device Management- Responsible for integrating all hardware and externally connected devices and storing the data. Also manages and coordinates the flow of information among the devices.
  • Memory Management- Responsible for keeping records of memory space that is used and what remains unused whilst avoiding manipulation of data.
  • Process Management- sets Task priorities and ensures everything is processed on time. Also handles information security and ownership.
  • Handling system calls- Handles all requests by programmers to perform certain roles or for any clarifications.

System Libraries

The kernel has to be alerted to carry out a task and numerous applications give out alerts. Let’s call these alerts as system calls now which is the correct technical term. The correct system call should be given out as each kernel has various system calls. These standard of library procedures including system calls are supported by system libraries. Most often Linux uses the GNU C Library.

System Tools

These are basically commands that lets the operating system access files, edit and add data and change file location or make any other changes to the default settings.

Development Tools

The above three components is enough to get your operating system started but you need to have additional tools and libraries to update your system and keep up with the changes. These additional tools and libraries are called toolchain. These toolchains are effectively development tools.

End User Tools

These are basically add-on tools and features that are not really necessary but will give the user a unique experience. These are browsers, multimedia tools and office suites.

Why Choose Linux?

Linux id definitely not the most popular or easy to use operating system. It is indeed a bit more complex than Android and other operating systems. But despite all of this, there are many reasons why you should choose Linux as your preferred operating system.

Let’s check out why you should choose Linux OS:

  • It is completely free of charge. You do not need to make any form of payment to use this operating system. You have the option of installing it on multiple devices at no cost. This makes it ideal for all home and work devices.
  • It is an open-source operating system that is not locked in changes by the developers. As a user you can make some modifications as you wish. You are permitted to change the original code and create your own custom version.
  • It is a highly secure OS that does not require any anti-virus software. It saves your device from malware, viruses, bugs and crashes. It is also well-renowned for strict data protection regulations.
  • Linux OS is the most preferred choice of an OS for developers as it easily allows for modifications. Also, it supports many computer languages such as Java, Python, C+ and Ruby. It also allows for integration of different applications to help in the coding and development process.
  • It is a flexible operating system that can be used across many devices ranging from phones, laptops, watches, fridges and other electronic devices.
  • Linux distributors can be located easily which makes it a highly accessible OS. Most companies modify the original Linux OS and distribute the specially designed ones. The most common Linux Distributions are Ubuntu, Linux Mint, Debian, Fedora and Arch Linux.
