In Arch Linux, packages are files containing the compiled software, along with any necessary files and metadata. These packages are used to install, update, and remove software on the system.
Packages in Arch Linux are stored in repositories, which are collections of packages that are maintained by the Arch Linux developers and community. When you install a package, Pacman (the default package manager for Arch Linux) downloads the package from a repository and installs it on your system.
Arch Linux uses a rolling release model, which means that package updates are continuously pushed to the repositories. This allows users to keep their systems up to date with the latest software without the need for a major release upgrade.
NTFS support refers to the ability of a system to read and write to NTFS (New Technology File System) formatted drives. NTFS is a file system used by Microsoft Windows to store and organize files on a hard drive or other storage media.

Ctrl+Alt+T.Enter:Linux is a free and open-source operating system created by Linus Torvalds in 1991. Torvalds, who was a computer science student at the University of Helsinki at the time, wrote the original code for the Linux kernel (the core of the operating system) as a personal project. The kernel was released under the GNU General Public License (GPL), which allows anyone to use, modify, and distribute the software.
Since then, the Linux operating system has evolved and grown through the contributions of a large and diverse community of developers. Many of the commands that are used in the Linux command line were written by these developers, either as part of the core operating system or as part of additional software packages. There are also many third-party utilities and tools that have been developed for use on Linux systems.
A Linux firewall is a security system that controls the incoming and outgoing network traffic based on predetermined rules. It is designed to protect a Linux system from unauthorized access or attacks from the Internet or other networks.
The Linux firewall works by evaluating incoming and outgoing network traffic against a set of rules. These rules can specify which types of traffic are allowed or denied, based on factors such as the source or destination IP address, port number, or protocol. When a packet of network traffic arrives at the firewall, it compares the packet against the rules and either allows or denies it based on the results of the evaluation.

In Ubuntu and other Debian-based Linux distributions, a deb package (short for “Debian package”) is a type of file used to package and distribute software. It is a binary file that contains all the files and metadata needed to install and run the software on a Debian-based system.
Deb packages have a ‘.deb‘ file extension and are typically distributed in a compressed format. They are used to package a wide range of software, including libraries, utilities, and applications.
Deb packages are designed to be easily installable and uninstallable, and they can be managed using the ‘dpkg‘ command-line tool or various graphical package managers, such as the Ubuntu Software Center or the GDebi Package Installer.
VirtualBox is a free, open-source virtualization software that allows you to run multiple operating systems on a single physical computer. It creates a virtual environment on your computer, known as a virtual machine, which acts as a separate entity from your host operating system. You can install and run multiple operating systems on separate virtual machines, each with its own virtual hardware and software resources.
VirtualBox is useful for testing and developing software, as it allows you to run different operating systems and applications in a controlled environment. It is also useful for running software that is not compatible with your host operating system, or for running multiple instances of the same operating system simultaneously.
Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine. It allows you to run JavaScript code outside of a web browser, on the server side.
