What is Linux and its function?

In today’s technology-driven world, the word “Linux” appears in many conversations about operating systems, servers, and programming. Although it’s often associated with tech experts and developers, Linux powers many devices that people use every day—even without realizing it.

So, what exactly is Linux, and what are its functions? Let’s explore its definition, history, components, and real-world uses.

What is Linux?

Linux is a free and open-source operating system (OS) based on Unix. Like other operating systems such as Windows or macOS, Linux manages the hardware and software resources of a computer, allowing users to interact with the system and run applications.

Unlike Windows or macOS, however, Linux is open-source, which means its source code is freely available for anyone to view, modify, and distribute. This openness has led to the development of hundreds of distributions (or “distros”)—versions of Linux tailored to different needs.

Key Characteristics of Linux:

Open Source: Anyone can modify and distribute it.

Free to Use: Most distributions are free to download and install.

Multiuser and Multitasking: Supports multiple users and concurrent tasks efficiently.

Highly Secure: Built-in permission and user management systems.

Customizable: Every component can be tailored for specific use cases.

Brief History of Linux

Linux was created in 1991 by Linus Torvalds, a Finnish computer science student, as a hobby project. He wanted to build a free and open-source alternative to the MINIX operating system, which was itself a Unix-like system used for teaching.

Torvalds released the first version of the Linux kernel, the core part of the OS, and it quickly attracted a global community of developers. Over the years, contributors around the world added features, developed graphical interfaces, and built complete systems using the Linux kernel.

Today, Linux is at the heart of operating systems used in servers, smartphones (like Android), supercomputers, and even IoT devices.

What is the Function of Linux?

At its core, the primary function of Linux—like any operating system—is to act as an intermediary between hardware and software. It allows users and applications to communicate with the computer’s hardware in a controlled and secure way.

What are the 5 basic components of Linux?

Linux operating is widely known for its speed, flexibility, and open-source nature. It's the backbone of everything from web servers and smartphones to supercomputers and Internet of Things (IoT) devices. But behind the sleek user interface or powerful command line lies a set of core components that form the structure of every Linux system.

So, what makes up a Linux operating system? To understand how Linux works, you need to explore its five basic components, each with a distinct role. These components are:

Kernel

System Libraries

System Utilities

Hardware Layer

User Interface

Together, they interact to perform essential functions, from managing memory and hardware to running applications and accepting user commands. Let’s explore each of these in detail.

1. The Linux Kernel – The Core of the OS

What it is:

The kernel is the heart of the Linux operating system. It's a low-level program that manages communication between software and hardware. Every Linux distribution (Ubuntu, Fedora, Arch, etc.) is built on top of the same core Linux kernel, though versions may vary.

Functions:

Process management – Handles the execution of programs, manages CPU time, and switches between processes.

Memory management – Allocates memory for applications and ensures that no program interferes with another's memory space.

Device management – Communicates with all hardware devices through drivers.

System calls and security – Offers an interface for user applications to request services securely.

Types of Kernels:

Monolithic Kernel (used by Linux): All core functions run in a single large process in kernel space, offering fast performance.

Microkernel: A minimal kernel with functions like device drivers and file systems running in user space.

Importance:

Without the kernel, Linux wouldn’t be able to boot, manage resources, or interface with hardware. It’s the most crucial component and runs in kernel space, separate from user applications for security and stability.

2. System Libraries – The Foundation for Programs

What they are:

System libraries are special functions or programs that allow applications and user-level programs to interact with the kernel. These libraries contain code used to perform standard tasks like input/output handling, string manipulation, and memory allocation.

Example:

The GNU C Library (glibc) is one of the most widely used system libraries. It provides standard C library functions and interfaces to kernel services.

Functions:

Abstract the complexity of system calls

Allow application developers to use reusable code

Enable portability between different Linux distributions

Importance:

System libraries prevent developers from having to write low-level kernel code to perform routine operations. Instead, they call a function in a library that handles the job efficiently and securely.

3. System Utilities – Essential Tools for System Operation

What they are:

System utilities (also called system programs or user-space utilities) are programs that perform essential tasks for managing the system. These can include software installation tools, disk partition managers, user account handlers, and file system tools.

Types:

Basic Utilities: File management (cp, mv, ls, rm)

Administrative Tools: Process monitoring (top, ps), package managers (apt, dnf, yum)

Networking Tools: (ping, ssh, scp, netstat)

File System Tools: (mount, fsck, mkfs)

Functions:

Support system administration

Provide tools for software development

Enable data management and access

Importance:

These utilities form the core user-level interface to interact with the OS and hardware. Without them, users wouldn’t be able to use the system productively.

4. Hardware Layer – The Physical Infrastructure

What it is:

The hardware layer refers to all the physical components of a computer system—CPU, RAM, hard drive, network card, graphics card, keyboard, mouse, and more. While not a software component, it’s vital because Linux interacts directly with it via the kernel and drivers.

Functions:

Execute instructions from the CPU

Store and retrieve data from memory and disk

Transmit and receive data via network interfaces

Accept input and provide output via peripheral devices

How Linux Interacts with Hardware:

Device drivers: Special kernel modules that act as translators between the kernel and hardware devices

/dev directory: In Linux, devices are represented as files (e.g., /dev/sda, /dev/tty), allowing user-level applications to interact with hardware via file I/O

Importance:

The entire Linux software stack ultimately depends on hardware to run. The kernel ensures proper management and efficient usage of the hardware layer.

5. User Interface – Interacting with the System

What it is:

The user interface (UI) is the part of Linux that allows humans to interact with the system. Linux supports two primary types of interfaces:

Command Line Interface (CLI)

Graphical User Interface (GUI)

CLI – The Shell:

The CLI is a powerful text-based interface where users can run commands.

Popular shells include Bash, Zsh, Fish, and Tcsh.

Advanced users and system administrators often prefer CLI for its speed, automation, and control.

GUI – Desktop Environments:

The GUI provides a graphical interface with windows, icons, and menus.

Common desktop environments in Linux:

GNOME (Ubuntu, Fedora)

KDE Plasma (Kubuntu, KDE Neon)

Xfce, LXQt, Cinnamon, MATE

Functions:

Accept user input

Display system output

Allow application management (open, close, configure programs)

Provide customization options

Importance:

While CLI offers power and flexibility, GUIs make Linux more accessible to everyday users. Many modern distributions include both, allowing users to choose based on preference and task.

How These Components Work Together

To illustrate how these five components collaborate, consider what happens when you open a text editor like Gedit in Linux:

User Interface: You click on Gedit’s icon in the GUI (or type gedit in the CLI).

System Utilities: The shell locates the Gedit program in the file system.

System Libraries: Gedit uses system libraries to interact with the OS.

Kernel: The kernel allocates memory, manages CPU resources, and accesses your files.

Hardware: Data is displayed on your screen and written to your disk using the system’s physical hardware.

Each layer depends on the others. If one component fails or is misconfigured, the whole system can be affected.

Conclusion

Understanding the five basic components of Linux—the kernel, system libraries, system utilities, hardware layer, and user interface—is essential for anyone learning Linux or working with it professionally.

These components work seamlessly to provide a robust, flexible, and efficient operating system that powers millions of devices worldwide. Whether you’re a beginner installing your first distro or an advanced user managing servers, appreciating these building blocks helps you harness the full power of Linux.

Linux isn’t just a free OS; it's a modular, customizable, and transparent platform built on these five critical components. Learn them, master them, and you'll gain a strong foundation in one of the world’s most influential technologies.

When Linux is introduced?

Linux course is now a foundational component of modern computing, powering everything from web servers and supercomputers to smartphones and smart TVs. But like all transformative technologies, Linux had humble beginnings. Its birth in the early 1990s marked a turning point in the evolution of operating systems—ushering in a new era of free and open-source software.

This article explores the question:

When was Linux introduced?

Alongside the timeline, we’ll delve into the context of its creation, the motivations behind it, and how it evolved into the global phenomenon we know today.

The Birth of Linux: 1991

Linux was officially introduced in 1991 by a then 21-year-old computer science student named Linus Torvalds, studying at the University of Helsinki in Finland. On August 25, 1991, Torvalds posted a message to the Minix newsgroup (comp.os.miix) announcing that he was working on a new free operating system kernel as a hobby.

Linus Torvalds' Historic Announcement:

"Hello everybody out there using minix – I’m doing a (free) operating system (just a hobby, won’t be big and professional like GNU) for 386(486) AT clones."

This message is now considered the moment Linux was officially introduced to the public.

The Context: What Led to Linux?

To understand why Linux was created, it helps to know what the computing landscape looked like in the late 1980s and early 1990s.

1. UNIX and Its Influence

UNIX was a powerful, multiuser, multitasking operating system developed in the 1970s at AT&T’s Bell Labs. It became highly influential in academic and commercial environments, but it was proprietary and expensive, which made access difficult for students and hobbyists.

2. MINIX: An Educational UNIX-Like OS

To address the problem of access, Andrew S. Tanenbaum, a professor at Vrije Universiteit Amsterdam, created MINIX in the late 1980s. MINIX was a small, UNIX-like operating system used for teaching OS concepts, and its source code was available for educational purposes.

However, MINIX had limitations:

It was not free for unrestricted use.

It was intended strictly as a teaching tool, not for practical, general-purpose computing.

This inspired Linus Torvalds to build something better—an OS kernel that was free, practical, and UNIX-like.

The First Version of Linux

Linux Kernel 0.01 (September 1991)

Shortly after announcing his project, Linus released the first version of the Linux kernel, version 0.01, in September 1991. It was very basic and included:

A terminal

File system support

Basic drivers for AT hard disks

However, it couldn’t yet be called a full operating system—it was just a kernel. What it lacked were the user-space tools (compilers, shells, editors, etc.) necessary to create a complete OS.

Collaboration with GNU

Around the same time, the Free Software Foundation (FSF), led by Richard Stallman, had developed many of the core components needed for a Unix-like system under the GNU Project (GNU = GNU’s Not Unix). However, the FSF lacked a working kernel—the missing piece of the puzzle.

Linux became that missing piece.

By combining the Linux kernel with the GNU userland tools, developers created the first complete GNU/Linux operating system. This collaboration laid the foundation for the many Linux distributions we know today.

Linux Licensing: The GPL

Initially, Linus used a custom license for his project. But in 1992, he decided to release Linux under the GNU General Public License (GPL v2). This was a crucial decision.

Benefits of GPL Licensing:

Allowed free use, modification, and redistribution

Encouraged collaborative development

Prevented the kernel from being used in proprietary software

This decision enabled Linux to grow rapidly as developers around the world began contributing code, fixing bugs, and adding new features.

The Rapid Growth of Linux (1990s)

From 1992 onward, Linux began to evolve rapidly thanks to community contributions and rising interest in open-source software.

Key Developments:

1993: The first Linux distributions (Slackware, Debian, Red Hat) were released, making installation easier.

1994: Linux 1.0 was released—considered the first production-ready version.

Late 1990s: Linux gained a strong foothold in the server market due to its stability and low cost.

Linux Enters the Mainstream (2000s and Beyond)

1. Enterprise Adoption

Major companies like IBM, Oracle, and Google began using and supporting Linux in the early 2000s. IBM invested $1 billion in Linux development, signaling corporate confidence in the platform.

2. The Rise of Distributions

Dozens of Linux distributions emerged, tailored to different user needs:

Ubuntu (launched 2004) brought Linux to mainstream desktop users.

Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) targeted businesses.

Debian, Arch, Fedora, and others served developers, power users, and enthusiasts.

3. Linux in Mobile: Android

In 2008, Google released Android, a mobile OS based on the Linux kernel. Today, Android powers the majority of smartphones globally, meaning Linux is the most widely used operating system in the world.

4. Linux in the Cloud and Supercomputers

Linux dominates the cloud computing infrastructure.

All of the top 500 supercomputers (as of 2025) run on Linux.

Modern Day Linux

Today, Linux is everywhere:

Servers (Apache, NGINX, etc.)

Desktops (Ubuntu, Mint, Fedora)

Smartphones (Android)

IoT Devices

Supercomputers

Raspberry Pi and education

Its development is overseen by thousands of contributors from companies like Intel, Google, IBM, and Red Hat, along with independent developers.

Conclusion

Linux was introduced in 1991 by Linus Torvalds as a personal project to build a free, Unix-like operating system for PC hardware. What began as a hobby turned into a global movement that reshaped the world of software.

From its modest beginnings as a kernel written by a single student, Linux evolved through community collaboration, open licensing, and innovation. Today, it is the foundation of the internet, the dominant server OS, and the core of mobile computing through Android.

Its introduction was not just the release of a piece of software—it was the start of a revolution in how software is created, shared, and improved. Linux embodies the spirit of openness, freedom, and community, and its story continues to inspire millions of users and developers worldwide.
