Package managers handle dependencies, ensuring that all required software components are installed correctly. Package Management: Linux distributions use package management systems to install, update, and remove software packages.
User management involves creating and managing user accounts, assigning permissions and privileges, and ensuring system security. User Management: Linux supports multi-user environments, allowing multiple users to log in and use the system simultaneously. The operating system manages processes, allocating system resources, scheduling their execution, and providing inter-process communication mechanisms. Processes: In Linux, a process is an instance of a running program. Common file systems used in Linux include Ext4, XFS, and Btrfs. Directories contain files and subdirectories, and the file system organizes them in a tree-like structure. Examples of popular Linux shells are Bash (Bourne Again Shell), C shell, and Zsh.įile System: Linux uses a hierarchical file system structure, starting from the root directory ("/"). It interprets the commands entered by the user and executes them. Shell: The shell is a command-line interface that allows users to interact with the operating system. It interacts directly with the hardware and manages system resources such as memory, processes, devices, and file systems. Kernel: The kernel is the core component of the Linux operating system. Whether you're a system administrator, developer, or simply curious about these technologies, this introduction will lay the groundwork for a deeper understanding of Linux operating systems and virtual machines. We'll also delve into the concept of virtual machines, understanding their types, benefits, and the software used to create and manage them. Let's explore the fundamentals of Linux operating systems, including the kernel, shell, file system, processes, user management, and package management. Meanwhile, virtual machines enable the efficient utilization of hardware resources by allowing multiple operating systems to run simultaneously on a single physical machine. Linux, known for its stability, security, and open-source nature, forms the foundation of numerous operating systems used across various devices and environments. Linux operating systems and virtual machines are two key components in the world of computing that offer powerful capabilities and flexibility.
