Introduction
Linux is a widely used Operating System developed in 1991 intending to provide various services for applications and manage computer hardware. It is an open-source Operating System (OS) widely used in web servers, smartphones, supercomputers, home appliances, cars, gaming, backup and recovery, repurposing old computer systems, etc. Linux is a free and open-source platform that allows easy access to features and tools, reduces installation and maintenance costs, supports easy customization, and offers excellent security and stability.
The Linux OS comes with Multi-user support and Command-Line Interface (CLI) to enable users to perform complicated tasks more effectively. This platform is interoperable with other Operating Systems and cloud computing platforms like Google Cloud Platform, Microsoft Azure, Amazon Web Services (AWS), etc. Various benefits have made Linux a highly chosen OS, leading to a significant rise in the demand for Linux experts. Therefore, many training institutes offer the Linux Online Course to help one learn more about this robust Operating System and develop their expertise in this framework.
This section explains the architecture of Linux. Read on to know more.
Linux Architecture
Linux has a comprehensive architecture with different components like Kernel, System Libraries, Hardware Layer, System Utilities Programs, and Shell. Let us look at the different Linux components in detail.
- Kernel
The Kernel is the core component of Linux. This carries out all the major functions of the Linux OS. The Kernel contains unique modules and cooperates with the underlying hardware directly. There are different types of Kernels like Monolithic Kernel, Micro Kernel, Exo Kernel, and Hybrid Kernel.
- System Libraries
The System Libraries in the Linux OS refer to some special functions applied to implement an Operating System’s functionalities. The System Libraries do not require any code access rights of the modules of the Kernel component.
- Hardware Layer
The next component of the Linux Operating System is the Hardware Layer which comprises various peripheral devices like the CPU, HDD, RAM, etc., that facilitate the functions of Linux.
- System Utilities Programs
The System Utilities Programs in the Linux Operating System framework have been designed to perform various specialized and individual-level activities within Linux.
- Shell
The Shell component of the Linux platform is an interface between the Kernel component and the user. The shell component can afford the services of the Kernel, take the commands through the user, and run various functions of the Kernel component. There are different types of Shells, like Korn Shell, Bourne Shell, C Shell, and POSIX Shell.
Conclusion
To sum up, Linux is a popular Operating System that provides various services for applications and manages computer hardware. This open-source and cost-effective OS is primarily used for web servers, smartphones, supercomputers, home appliances, cars, gaming, backup and recovery, repurposing old computer systems, etc. Linux offers a number of useful tools and other features to make the work of the users easier. In addition, its free nature makes this platform highly useful for companies, leading to higher demand for Linux professionals in the industry. Therefore, one must consider joining the Linux Online Training to develop their skills on the Linux platform and advance in their career. Linux has a comprehensive architecture with different components like Kernel, System Libraries, Hardware Layer, System Utilities Programs, and Shell. Each of these Linux components has unique functions that facilitate the operations using the Linux Operating System.
