Nothing can replace hands-on experience, it's true. A study was conducted and it proved that you are more likely to remember something if you actually have done it. That's why a virtual lab is important. I, for one, have had a few labs of my own. I started when I practiced for my CompTIA A+ exams, I also had a lab for when I was studying for CISCO, I had one when I did a self study on Computer Systems Servicing NCII and I have one now while I'm on track for my Windows Server certification. I always did remember a lot through the use of these labs wherein a did tasks one after another more than once. And whatever configurations I did, did not affect my physical device's setup.
Virtual labs are made possible by the technology known as virtualization. It literally has broken the barrier to lots of things. Let's enumerate and explain some.
2. Virtual labs are safe for practice. Safe in a sense that if you try to configure something that has a potential to disrupt your configuration totally, you need not worry because if you made a mistake you just build it again and that has no effect on your physical system.
3. In a business perspective, companies don't need to have hundreds of bulky heavy machines in their environment. Nowadays, they maximize the use of virtualization by building all of their servers in just one, two or three physical machines. This has greatly reduced the cost for purchase and maintenance.
Virtualization does have tons of benefits but for our purpose, we only need to learn a few - the basics. It does have, as most things do, some catch. The first concern is the ability of your device (desktop / laptop) to support virtualization. If it does, how many machines can it support? Typically, the ideal machine to build a virtual lab on is one that has is a 64-bit architecture.
64-bit systems break the limit for memory usage, thus, you can have more than 4 GB in your system. Keep in mind that when you create one (1) virtual machine, the resources that you allocate to it are really being taken from the physical machine.
For instance, consider the following specifications:
This machine only has 3 GB of memory. It's possible to create a virtual machine on top of this device but it will greatly strain the physical machine. If I gave the virtual machine 1 GB of RAM, the physical machine is left with 2 GB which is not enough to carry out multiple processes at one time. Can't we add some memory then? Yes, we can. But since it's a 32-bit Operating System on a 32-bit machine, we can't exceed more than 4 GB.
If your machine is virtualization capable, we can create our virtual environment. Please download the following installers that we will use.
Note that you need to register before you can download.
thanks much, sir!
