Linux is a collection of Unix-like operating systems that are free and open source. It is a collection of applications that serve as a conduit between the user and the computer.
Since its inception in the mid-1990s, the Linux Operating System has grown in popularity across sectors and countries. It powers the majority of the Internet, as well as scientific supercomputers and stock markets throughout the world. But, even before it became renowned as the platform for running PCs, servers, and embedded systems all across the world, Linux was regarded as one of the most dependable, secure, and worry-free operating systems available.
The components of the architecture that unifies all Linux versions are as follows:
1. The kernel
The kernel is the operating system’s brain. It’s the operating system’s lowest level, and it’s in charge of converting commands into something the computer can understand. Most activities, such as memory management, task scheduling, and file management, are handled by it.
2. Use the Command Line
The command line is a text-based computer interface. It’s a software that receives commands and sends them to the operating system of the computer to execute. You can navigate your computer’s files and directories from here.
The Linux command line may appear complicated and scary at first, but once you get used to it, you’ll find it to be fairly straightforward and simple to use.
Linux prefers to provide you with a collection of building pieces and then let you to put them together. This enables you to construct and assemble items that meet our requirements.
3. Shell
The shell is the program that deals with your requests. When you input a command into your terminal, the shell understands it and invokes the desired application. Basically, you use this software to connect with the kernel. The most well-known main shells are the C Shell, Bourne Shell, and Korn Shell.
4. Utilities and Commands
There are a variety of commands and utilities that you may utilize in your daily tasks. There are approximately 250 basic commands, as well as a plethora of additional available through third-party applications. All of the commands come with a variety of alternatives. The goal is to be sluggish. Why should you do anything if the computer can do it for you?
The only explanation I can think of is that you don’t know how, but once you do, you’ll be able to, therefore there won’t be any excuse.
5. Directories and Files
In Linux, all data is arranged into files. After that, all of the files are sorted into folders. These folders are then arranged into a filesystem, which is a tree-like structure.
