Course Details
At its core, Linux is an operating system (OS), similar to Windows and macOS, that manages hardware resources, provides an interface for user interaction, and allows software applications to run. It is open-source, meaning the source code is freely available to anyone, and it can be modified and distributed by anyone under the terms of its license (primarily the GNU General Public License (GPL)).
Linux
Linux is an open-source, Unix-like operating system that has gained widespread adoption across a variety of environments, from personal computing to enterprise servers and mobile devices. It has become one of the most powerful and flexible operating systems in the world due to its security, flexibility, and the support of a vast global community. Here's a detailed exploration of Linux, from its origins to its present-day applications.

History and Origins of Linux
Linux was created by Linus Torvalds in 1991 as a personal project. Torvalds, a Finnish computer science student, wanted to create a free and open version of the Unix operating system that could run on personal computers. Inspired by the design of Unix but aiming to improve its accessibility, Linus released the initial version of the Linux kernel (version 0.01) in 1991.
Linux Kernel
The kernel is the core part of the Linux operating system.
Monolithic Kernel: The Linux kernel is often described as a monolithic kernel, meaning that it manages all essential functions within the kernel itself.
System Calls: The kernel provides system calls that allow programs to request services from the hardware .
Key Components of Linux
Shell: The shell is the command-line interface (CLI) of the Linux operating system.
File System: Linux uses a hierarchical file system structure with directories like /bin, /home, /etc, and /root.
System Libraries: System libraries are pre-written functions that programs can call to perform tasks without needing to implement them from scratch.
Distributions (Distros)
Ubuntu: One of the most popular Linux distros for beginners and desktop users. Ubuntu is known for its user-friendliness and ease of installation.
Debian: Known for its stability and use as a base for many other distributions, including Ubuntu.
Fedora: A cutting-edge distribution sponsored by Red Hat that features the latest in open-source technology.
Advantages of Linux
Free and Open-Source: Most Linux distributions are free to use, with no licensing costs.
Security: Linux has strong security protocols in place, such as user-based permissions and frequent security updates.
Flexibility: Linux can be customized to meet specific needs, from lightweight systems to powerful server configurations.
