Operating Systems

Linux

Linux is a free and open-source Unix-like operating system kernel that serves as the core component of many operating systems, commonly referred to as Linux distributions. It provides essential services such as process management, memory handling, device control, and networking, enabling software to run on a wide range of hardware from servers to embedded devices. Developed by Linus Torvalds in 1991, it is widely used in enterprise servers, cloud computing, supercomputers, and as the basis for Android on mobile devices.

Also known as: GNU/Linux, Linux OS, Linux kernel, Linix, Lunix

🧊Why learn Linux?

Developers should learn Linux because it is the dominant platform for server-side development, cloud infrastructure, and DevOps, offering stability, security, and customization. It is essential for deploying web applications, managing containers with Docker, and automating tasks through shell scripting, making it crucial for backend engineers, system administrators, and anyone working in cloud-native environments. Knowledge of Linux also enhances understanding of operating system concepts and command-line proficiency.
