What Are Linux Computers? A Complete Guide for Businesses

Updated on October 7, 2025, by Xcitium

In a world dominated by Windows and macOS, many IT managers and executives ask: what are Linux computers, and why are they important? Surprisingly, Linux powers over 90% of the world’s cloud infrastructure, most of the internet’s servers, and countless cybersecurity tools.

Introduction: Why Linux Matters in 2025

Understanding Linux computers isn’t just for developers—it’s crucial for business leaders, IT managers, and security professionals who want cost-effective, secure, and scalable systems.

What Are Linux Computers?

At its core, Linux computers are devices that run the Linux operating system, an open-source alternative to proprietary platforms like Windows or macOS.

Key Features of Linux Computers:

• Open-Source – Free to use, modify, and distribute.

• Secure – Known for strong security architecture.

• Customizable – Supports thousands of distributions (Ubuntu, Fedora, Debian).

• Lightweight – Can run on older or resource-limited hardware.

• Reliable – Powers servers, data centers, and mission-critical infrastructure.

👉 In short: Linux computers are flexible, secure, and cost-efficient systems that power everything from personal laptops to enterprise-level servers.

Why Linux Is Different From Other Operating Systems

When asking what are Linux computers, it’s important to compare them with mainstream platforms.
