• Wide range of software: There is a wide range of software available for Linux, including both free and commercial software.

What is the workflow of Linux?

The workflow of Linux involves several key components and processes. Here is a brief overview of the Linux workflow:

• Booting: When a Linux system starts up, the boot loader is loaded into memory and is responsible for initializing the kernel. The kernel then initializes the hardware and loads necessary drivers.
• Kernel: The kernel is the core of the Linux operating system. It manages system resources, such as memory, processes, and hardware devices. It provides an interface between the hardware and the software running on the system.
• Shell: The shell is the command line interface through which users interact with the operating system. It allows users to execute commands, run scripts, and manage files and directories.
• File System: Linux uses a hierarchical file system, where files and directories are organized in a tree-like structure. The root directory is denoted by a forward slash (“/”), and all other directories and files are located within this hierarchy.
• Processes: Linux is a multitasking operating system, which means it can run multiple processes simultaneously. Each process is assigned a unique process ID (PID) and has its own memory space.
• Networking: Linux provides robust networking capabilities, allowing users to connect to local and remote networks. It supports various network protocols and provides tools for configuring network settings.

How Linux Works & Architecture?

The architecture of the Linux operating system comprises key components, including the Kernel, System Library, Hardware layer, System, and Shell utility.

1. Kernel Overview: As a fundamental element of the operating system, the kernel plays a central role in overseeing major actions within the Linux OS. It encompasses various modules and interacts directly with the underlying hardware. The kernel provides essential abstractions to conceal low-level hardware or application program details from the system. Below, we outline some significant types of kernels.

• Monolithic Kernel
• Micro kernels
• Exo kernels
• Hybrid kernels

2. System Libraries: These specialized functions can be designated as system libraries, serving to implement the functionality of the operating system. They operate without requiring code access rights to the kernel’s modules.
3. System Utility Programs: These programs are tasked with carrying out specific and individualized activities at a specialized level.
4. Hardware Layer: Within the Linux operating system, the hardware layer encompasses various peripheral devices such as the CPU, HDD, and RAM.
5. Shell: It serves as a bridge between the kernel and the user, enabling access to kernel services. Accepting user commands, it executes kernel functions. Shells come in various types, found in different operating systems, broadly classified as graphical and command-line shells.

Graphical shells support a user-friendly interface, whereas command-line shells facilitate text-based interaction. Both types of shells carry out operations, but graphical user interface shells tend to operate at a slower pace compared to command-line interface shells.

Several shell types include:

• Korn shell
• Bourne shell
• C shell
• POSIX shell
