Today I will talk you about virtual machines. Maybe this is new for you: virtual machines are enviroments in what we can emule hardware like a Personal Computer in this way we can run a Operating System inside it. The development of this enviroments has been so big that even we can install many virtual machines inside a PC, and if your hardware support it - I speak about processor and memory - you can execute them at the same time, even set up in network as they were real machines.
These virtual enviroments are frequently used now in many corporate enviroments of several modes. They has so many advantages that I will try to describe some of them:
1. You can install the virtual machine inside a PC and move it to other PC’s, in this way you don’t need to install operating system in every PC with virtual machine.
2. You can use virtual machines to test all kind of software without worry to damage you operating system, no data loss. I will show how to execute malicious software and analize its behaviour inside virtual machine without any risk for the real machine.
3. You can create Snapshots, they act like Norton Ghost Images. We can restore a previous saved state whenever we want after test software, viruses and trojans in virtual machines.
4. You can set up the virtual machines to share resources in your network, etc, etc.
VMWARE:
VMWare is commercial software and you have to buy it :(. But you can use it using trial version. This enterprise is specialist developing virtualization software. There are many types, I will use now VMWare WorkStation 6.0. Trial Version expires in a time and you must purchase a license to continue using it 
. The advantages of this software and I like them are: Skill to set up network in several modes: local, bridge, Nat and No Connection modes. Also you can set up resources: amount of memory to use, disk space, processor, CD, Diskette, sound, video and network you want to use with the created virtual machine. You can install several Operating Systems: all Microsoft Operating System family, since DOS up to Windows Vista, Linux family even Solaris and * BSD. You can download pre-installed operating system image, so you don’t need to install all Operating System.
Let’s proceed to describe installation process:
1. Download VMWare Workstation from www.vmware.com .
2. Once downloaded the Installer, we execute it.
