What is Linux?
Linux is a Unix like Open source operating system for computers, servers, mainframes, mobile devices as well as the embedded devices. Linux is one of the most widely supported operating systems on major computer platforms like X86, ARM as well as the Sparc.
Since today many people, use the GUI based Windows Operating System, it is necessary to create the Linux Environment to execute the commands. And it is not suggestible to use a separate device for the separate environment. Besides removing the current environment and creating a new process is not a good way of environment creations And dual boot system may not work in all the system (requires the high configuration) and slows down the system performance. So at the moment, Virtual machines are the best platforms to create Linux environments.
