linux introduction Linux is an open source operating system (OS). Linus Torvalds is the developer of the Linux operating system on 1991. first name with the word "Unix". An operating system is the Software that directly manages a system's hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work. Open source software (OSS) is software that is distributed with its source code, which allows anyone to inspect, modify, and enhance it. Open Source is a software with source code. Source code is a set of human resource code. The Linux kernel is the core component of the Linux operating system (OS ). It's a Unix-like kernel that acts as an interface between a computer's hardware and its processes, and is responsible for managing the computer's low-level functions.
Kernel
Types of Kernal Microkernel Monolithic Hybrid
Microkernel The bare minimum of software required to provide the mechanisms required to implement an operating system (OS) is known as a microkernel. Low-level address space management, thread management, and inter-process communication (IPC) are some of these processes.
Monolithic A monolithic architecture is a traditional model of a software program, which is built as a unified unit that is self-contained and independent from other applications . The monolithic operating system is a very basic operating system in which file management, memory management, device management, and process management are directly controlled within the kernel. The kernel can access all the resources present in the system.
Hybrid Hybrid operating systems combine elements from different architectures to achieve better performance, flexibility, reliability or security. For example, Windows NT is a hybrid operating system that uses a microkernel for the core services and a monolithic kernel for the drivers and subsystems.
Career opportunities Linux knowledge is highly valued in IT jobs like software development, system administration, network engineering, cyber security, with 66% of hiring managers citing it as a significant factor.

What are the different types of open-source licenses? Open-source licenses are categorized as either permissive or copyleft , and both allow for software distribution and modification. They usually require attribution and disclaim liability.
Future-proofing Linux is a popular, open-source operating system that's used in many areas, Servers , cloud computing DevOps environments. Learning Linux can provide a strong foundation for future opportunities and knowledge.
Productivity and Ease of use Productivity Linux can help you be more productive by teaching automation and encouraging you to write scripts. It can also help improve security and system management . Ease of use Linux is considered simple and easy to use, and it offers many customization options.
Advantages of Linux Linux is a popular operating system for many reasons, including Open source Linux is free and open source, so users can modify and distribute it as they like. It's developed by a wide range of contributors, not a single company, so developers can make improvements. Customizable Linux is highly customizable, allowing users to tailor the system to their specific needs. This makes it a great choice for businesses. Reliable Linux is known for being reliable compared to other operating systems, with fewer issues experienced by most users. This is partly because Linux focuses on background process management. Security Linux has enhanced security features, such as the chmod command, which sets read, write, and execute permissions for every object on the system .
Advantages of Linux Scalability Linux can handle large amounts of data and traffic. Compatibility Linux is compatible with modern DevOps practices and configuration management. Community support Linux has a community that provides support and resources. Ease of installation Most Linux distributions come with a simple GUI-based installation wizard that makes it quick and easy to install.
Advantages of Linux Range of applications and tools Linux comes with a range of applications and tools, including GIMP, a powerful image editing software. Cost-effective Linux is often more cost-effective than proprietary software.
