Linux is a computer operating system (OS) designed in the project of free and open-source software development and distribution model. Its most important component is Linux kernel. The operating system’s kernel was first released on October 5, 1991, by Linus Torvalds. Linux has originally developed as free OS for Intel x86 architecture based personal computers.
Linux’s development is the biggest example of free and open-source software collaboration. Its most important thing is that anyone can source or modify the source code on terms and conditions of respective licenses (such as the GNU General Public License) commercially or non-commercially. Linux is delivered in a customizable package, which is called Linux distribution and this package is built for both desktop and server. Some of the popular Linux distributions are named Linux, Santos, Debian, Fedora, Genetube Linux, Linux Mint, Majia, OpenSSL and Ubuntu and some commercial category distribution packages – Red Hat Enterprise Linux and SUSE Linux Enterprise Server.
What is Linux Kernel – is the central module of the kernel operating system. This is the part of the operating system which is the first load and then gets transferred to the main memory. the kernel is the interface that interacts with hardware in any computer.
Linux is fast, free and powerful. Linux has some important and basic features –
Portable – Portable here means software supports different types of hardware Linux kernel and application programs support installation on any kind of hardware platform.
- Open Source – Linux source code is freely available and is a community-based development project. Multiple teams work on Linux continuously to enhance and evolve Linux’s capability.
- Multi-User – System resources like memory/ram/application programs can access multiple users simultaneously.
- Multiprogramming – Multiple applications can be run simultaneously at one time.
- Hierarchical File System – Yes supports standard file structure, where system files/user files are arranged in a hierarchical way.
- Security – Linux provides authentication features such as password protection or encryption features.
