Twenty Most Used Linux Commands

December 20, 2022December 23, 2022 oarsman No Comments

Who Created Linux and Its Commands?

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.

December 19, 2022December 23, 2022 oarsman No Comments

What is VirtualBox?

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.
