What are the main features of Linux?

Linux is known for its numerous features, which contribute to its popularity and versatility as an operating system. Here are some of the main features of Linux:

Open Source: Linux learning is distributed under open-source licenses (usually the GNU General Public License), which means that its source code is freely available for anyone to view, modify, and distribute. This fosters collaboration, transparency, and a vibrant community of developers and users.

Unix-Like Behavior: Linux follows Unix principles and behavior, making it compatible with many Unix utilities and commands. This familiarity with Unix is advantageous for administrators and developers.

Multiuser: Linux is inherently multiuser, allowing multiple users to log in and use the system simultaneously while keeping their processes and data separate. User accounts and permissions control access to resources.

Multitasking: Linux supports multitasking, allowing multiple processes to run concurrently. The operating system's scheduler allocates CPU time to each process, ensuring efficient resource utilization.

Stability and Reliability: Linux is known for its stability and reliability. It can run for extended periods without needing to be rebooted, making it suitable for critical server environments.

Security: Linux provides robust security features, including user and group permissions, access control lists, and mandatory access controls (e.g., SELinux). Regular security updates and patches are released to address vulnerabilities.

Networking: Linux has excellent networking capabilities, making it ideal for servers and network infrastructure. It supports various networking protocols and services, including TCP/IP, DNS, DHCP, and VPN.

File System Support: Linux supports a wide range of file systems, including ext4 (the default for many distributions), Btrfs, XFS, ZFS (in some distributions), and more. This flexibility allows users to choose the most appropriate file system for their needs.
