Linux

Linux is a powerful, open-source operating system kernel that forms the foundation of various operating systems (known as distributions or distros). It is widely used for servers, desktops, embedded systems, and cloud infrastructure. Its flexibility, security, and cost-effectiveness make it an essential skill in the tech industry.

Linux is incredibly versatile, with applications across various industries:

Web Servers and Hosting

• Powers over 90% of cloud servers globally, including those running platforms like AWS, Google Cloud, and Microsoft Azure.
• Example: Popular web servers like Apache, Nginx, and databases like MySQL run seamlessly on Linux.

Software Development

• Provides a stable and robust environment for developers to build, test, and deploy applications.
• Example: Developers often use Linux for containerization with tools like Docker and Kubernetes.

Cybersecurity and Networking

• Integral to penetration testing and system security analysis.
• Example: Security professionals use Linux-based tools like Kali Linux for ethical hacking and vulnerability assessments.

Embedded Systems and IoT

• Linux is the go-to choice for operating systems in smart devices, robotics, and embedded systems.
• Example: Devices like Raspberry Pi and smart TVs often run Linux-based systems.
