Introduction.
At one time the term virtual PC referred to a software package that would allow an Apple Mac computer to act as if it were an IBM compatible PC, running MS Windows. In other words it allowed the Apple Mac to emulate the IBM compatible PC. Today the term virtual PC has a much broader application, which you might like to discuss in more detail with an established and reputable IT consultancy in Hong Kong.
Virtual PCs and virtualization.
One explanation of what are virtual PCs' would simply be a computer that has more than one operating system installed on it. As stated above this could be an Apple Mac which is also running Windows or even an IBM compatible PC running the Mac OS; it could even mean simply having more than one version of MS Windows installed on a single PC such as XP and Vista. However, the growth and improvement in what are referred to as 'open source' OS, such as Linux or Solaris, are also now quite commonly used as virtual PCs. Basically it is a method of virtualization that allows various OS to run 'under' the original OS installed on a PC. Operating a virtual PC can be quite straightforward, following some advice from your IT services provider, provided the PC you're installing the extra OS on has plenty of spare processing power, RAM and hard-disk space. However, a perfectly natural question to ask is - why go for the virtualization of a PC?
Why have virtual PCs?
A common question asked of Hong Kong IT consultancy's is - why would anyone want to have virtual PCs? To answer that question first lets take the example of a PC with MS Windows XP and Vista installed on it. Whether you're a home or business user, we all know that there is invariably a transition period between moving from one OS to another when you feel entirely dependant on your PC support service. You might need to check that certain legacy software will run satisfactorily on the new OS or just get your head around how to handle the OS. Being able to have both operating systems, one running in a virtual environment on the host computer, is an ideal way to test everything out over a period of time before deciding whether or not to fully migrate to the newer OS. Regarding having open source OS installed these can give you double and even triple booting options in the event of one operating system failing, which could be vital for business users who must be able to access their data 24/7, come what may. Alternatively, you could use one OS solely for online activities to improve your IT security, that way you can reduce the risk of data hacking or corruption without having to repartition your hard-drive.
Networked virtual PCs.
Many computer networks consist of a network server connected to PCs with their own processors and hard-disks. If you're looking for new network solutions that will lower your operating costs, there is a system of networking PCs, from a powerful server, whereby the workstations on the network do not need their own processors, hard-disks and, therefore, OS. This system is commonly referred to as a thin client system network. Again there are many versions of such networking systems available from the usual blue chip companies like MS and Sun etc; but there are also many smaller companies offering thin client solutions including a Hong Kong IT services company1 that produces a thin client system for the Windows platform.
Cloud computing.
Although still in its infancy in terms of massive following by the public - cloud computing is a progression in the concept of virtual PCs. In cloud computing you don't have to have an OS on your PC in the conventional sense, instead you in effect rent software and storage space from a web based server, which also gives you connection to other computers through the internet. However, for the moment - we'll look in more detail at cloud computing another time, or get in touch now with Dual Layer IT Solutions Hong Kong.
