Virtual computers in a virtual world

Filed under

The method I like the best for evaluating different operating systems, whether they are different Linux distributions, BSD, MacOS or the latest windows offering, is to use virtual machines. This means that with the quality of virtual machine programs available now, these operating systems you are evaluating run at near native speed. In fact you would be hard put to notice the difference with relatively modern hardware.

Even better is that while you are evaluating this new and exiting version of, say, Ubuntu, Mint, Fedora or Arch Linux, your existing operating system is also active and can be used at the same time. Providing you have enough memory and CPU power you can have more than one virtual machine running concurrently. On my pretty standard (sub standard by today's standards) of an AMD 5200+ CPU and 2Gb ram I have had three virtual machines running side by side as well as my, at that time, Debian operating system serving web pages and managing email. With a good virtual machine program, I use virtualBox myself, you are only limited by the amount of hard disk space and ram on your beast box.

Using a virtual machine program you can easily create and delete your virtual machines, making evaluation of different operating systems an easy task.

Learning The Linux File System

Before we get started, let’s avoid any confusion. There are two meanings to the term “File System” in the wonderful world of computing: First, there is the system of files and the directory structure that all of your data is stored in. Second, is the format scheme that is used to write data on mass storage devices like hard drives and SSD’s. We are going to be talking about the first kind of file system here because the average user will interact with his or her file system every time they use a computer, the format that data is written in on their storage devices is usually of little concern to them. The many different file systems that can be used on storage is really only interesting to hardware geeks and is best saved for another discussion. Now that that’s cleared up, we can press on.
