What is Linux? Features of the Linux Operating System

Linux is an open-source, Unix-like operating system. Initially developed by Linus Torvalds in 1991, Linux is now used by millions of users and devices worldwide. Key advantages of Linux include security, customizability, and cost-effectiveness.

1. What is Linux?

Linux is an open-source operating system that derives from Unix. It comes with a kernel and is available in various distributions. Each distribution comes with different software and features, allowing users to choose based on their needs.

Key Components of Linux:

• Kernel: Acts as a bridge between hardware and software, managing hardware resources.
• Libraries and Tools: Supports kernel functionalities with additional libraries and utility programs.
• User Interface: Provides interaction through command-line (CLI) or graphical user interface (GUI).

2. Features of the Linux Operating System

Linux has many features that distinguish it from other operating systems:

• Open Source: The source code is open to everyone, allowing users to view, modify, and distribute it. This promotes community contributions and transparency.
• Security: Linux offers robust security features, protecting against malicious software through user permissions and security policies.
• Customizability: Users can customize the operating system according to their needs. Various desktop environments and software packages are available for a personalized experience.
