What is Linux?
Linux is an operating system-a basic software that lets computers run programs and manage hardware. It’s free, open-source, and works on many different devices, from phones to supercomputers.
Let's break it down
- Operating system: the core program that controls everything on a computer, like a manager for hardware and other software.
- Free: you don’t have to pay to use it; anyone can download it.
- Open-source: the source code (the instructions) is publicly available, so anyone can look at, change, or improve it.
- Works on many devices: Linux can be installed on tiny gadgets, laptops, servers, and huge data-center machines.
Why does it matter?
Because it gives users and companies a powerful, customizable, and cost-effective way to run computers without being locked into expensive, proprietary software. It also encourages learning and collaboration in the tech community.
Where is it used?
- Web servers: Most of the world’s websites run on Linux machines because they’re stable and secure.
- Smartphones: Android, the most popular mobile OS, is built on the Linux kernel.
- Embedded systems: Devices like routers, smart TVs, and IoT gadgets often run lightweight Linux versions.
- Supercomputers: The majority of the fastest research computers use Linux for its performance and flexibility.
Good things about it
- No licensing fees, which lowers costs.
- Highly customizable - you can tailor it to exactly what you need.
- Strong security and frequent updates from a global community.
- Excellent stability; it can run for months or years without rebooting.
- Wide hardware support, from old PCs to the newest servers.
Not-so-good things
- Can be intimidating for beginners because of command-line tools.
- Some commercial software and games are not available natively for Linux.
- Hardware drivers may be missing or less polished for very new or niche devices.
- Support may rely on community forums rather than dedicated phone or in-person help.
