How Linux Works?

  Linux is a free and open-source operating system that is based on the Unix operating system. It is composed of the Linux kernel, which is the core of the operating system, and a set of user-space programs and libraries that provide common services and interfaces. The Linux kernel is responsible for managing system resources, such as memory and CPU time, and providing services to user-space programs through system calls. It also includes device drivers that allow it to interact with hardware devices, such as storage devices and network interfaces. User-space programs and libraries provide a wide range of functionality, including system utilities, such as the command-line shell and text editors, as well as graphical user interfaces, web browsers, and programming languages. These programs and libraries are typically written in C and C++ and are executed by the kernel through system calls. Linux also supports a wide range of file systems, including ext4, XFS, and NTFS, as well as net...

Why we create root partition and home partion in linux

In a Linux system, it is common to create a separate partition for the root directory (/), which is the top-level directory in the file system hierarchy, and a separate partition for the home directory (/home), which is the directory where users' personal files are stored. There are a few reasons why it is useful to create separate partitions for these directories: Security: By separating the root directory and the home directory onto different partitions, it is possible to protect the system files in the root directory from accidental or intentional modification by users. This can be especially useful on systems where multiple users have access. Organization: Having separate partitions for the root and home directories allows for better organization of the file system. System files and configuration files can be stored in the root partition, while users' personal files can be stored in the home partition. Backup and restore: If the root and home directories are on separate par...

How I can increase my root partition size in arch Linux

  To increase the size of your root partition on Arch Linux, you will need to follow these steps: Boot from a live Arch Linux USB or DVD. Use the fdisk utility to delete the root partition and create a new one with a larger size. Use the mkfs.ext4 utility to format the new root partition. Mount the new root partition to a temporary location. Use the rsync utility to copy the contents of the old root partition to the new root partition. Update the /etc/fstab file to reflect the new root partition. Reboot the system and verify that the root partition has been resized. Please note that these steps will involve deleting and recreating the root partition, which means that you will need to make sure that you have a backup of all important data before proceeding. It is also a good idea to read the documentation for the utilities that you will be using to make sure that you are using them correctly.
