Introduction
Linux architecture has the following components :
Kernel :
The kernel acts as the brain of a Linux-based operating system.
It organizes and oversees how the computer's basic elements like memory and processing power are used.
The kernel ensures that different programs don't interfere with each other or cause conflicts.
It handles communication between the computer and things like printers, keyboards, and network connections.
The kernel provides tools for programs to get things done, like saving files, connecting to the internet, or showing things on the screen.
It helps the computer remember what programs are doing and where they put their stuff in memory.
The kernel of a Linux-based operating system is typically written in the C programming language.
Shell :
The shell is like a talking point for the Linux Operating System.
Users can talk to the system by typing commands into the shell.
The shell understands these commands and does what users want.
It links users with the core part of the system, called the kernel.
The kernel is written in the C language, the shell helps bridge the gap between human language and the language the kernel understands.
Users tell the shell what to do, and then the shell tells the kernel.
The shell makes it easy for users to do things like run programs, organize files, and set up the system.
Different shells, such as Bash, Zsh, and Fish, offer various features and capabilities, allowing users to choose one that best suits their preferences and workflow.
Bash, one of the most commonly used shells, is a superset of the older shell called "sh" (Bourne Shell), providing more features and capabilities.
System Library :
Linux uses system libraries, also known as shared libraries, to make the operating system work.
System libraries act as a bridge between applications and the kernel, which is the core part of the operating system.
These libraries contain ready-made code that programs can use to do specific tasks.
They provide a standardized and efficient way for programs to communicate with the underlying system.
Developers benefit from using these libraries because they don't have to write the same code again and again, saving them time and effort.
System libraries are regularly updated and maintained by the Linux community, ensuring stability and security for the entire system.
Hardware :
The hardware layer of Linux operates at the lowest level of the operating system track.
It plays a crucial role in managing all hardware components.
This layer encompasses :
Device drivers
Kernel functions
Memory management
CPU control
I/O operations
Its main function is to simplify hardware complexity.
The hardware layer ensures that all components work together properly.
Application / System Utility :
System utilities are important tools and programs in Linux.
These utilities can install software, set up networks, and monitor system performance.
They help manage and configure different parts of the system.
System utilities make it easier for users to maintain their Linux systems efficiently.
They also handle tasks like managing users and controlling permissions.
System utilities also provide tools for system monitoring and troubleshooting, such as checking system logs and diagnosing hardware issues.
Conclusion
In summary, the Linux architecture consists of key components working together
smoothly :
Kernel : It's like the brain of Linux, handling resources and making sure everything runs smoothly and safely.
Shell : This is how you talk to Linux. You tell it what to do, and it does it for you. It's like a helpful assistant for your computer tasks.
System Library : These are like toolkits for programs. They make it easier for software to work with the computer's core, so developers don't have to start from scratch every time.
Hardware : These are the physical bits of your computer, like the keyboard and memory. Linux knows how to use them effectively to do what you want.
Application/System Utility : These are handy programs that help you manage your computer. They do things like install software, set up networks, and keep an eye on how your system is doing.
These components are like the building blocks of Linux. They work together to make sure your computer works well for all kinds of tasks.
