I will be describing a Term – Computer Virtualization; exploring what it is and what benefit is reaped in the real world. [1] Computer Virtualization transforms server hardware into software. Using software to transform, or “virtualizes” the hardware resources of a server—including the CPU, RAM, hard disk and network controller—to create fully functional virtual machines that can run their own operating systems(OS) and applications(apps).
Multiple virtual machines share hardware resources without interfering with each other so several operating systems and applications can run at the same time on a single server. This reduces the amount of hardware, power and storage space required to run multiple servers by a substantial percentage, which in turn reduces costs.
Most computer users, in the office or at home, are using a computer that runs one OS. Whether you are using a Mac, Linux or Windows computer you have the ability to run a 2nd, 3rd or more OS’s.
What is Virtualization? A company that specializes in leasing servers to small companies defines it as [1] “Today’s powerful server hardware was originally designed to run only a single operating system (ie. Windows, Mac, Linux) and a single application, but virtualization breaks that bond, making it possible to run multiple operating systems and multiple applications on the same server at the same time, increasing the utilization and flexibility of hardware while minimizing overhead and related costs.”
Virtualization is a technology that can benefit anyone who uses a server, from IT professionals and computing enthusiasts to commercial businesses and government organizations.” Though home and office users do not use servers, the same can be said about home computers as w...

...our host allowing you to now run up to seven (7) virtual machines inside your host. FYI: OS Licenses – you will need a license for each Virtual Machine (VM) you plan to run. Even though each VM is, in fact virtual, Microsoft and Mac still require you to obtain a license for each instance. Linux’ license is open source and free.
The Tools: You will need either VMware or Microsoft Virtual PC; both are free. Download, save energy and enjoy.

Essay on Virtualization in Computer Science

- Virtualization, in computing, refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. The term "virtualization" traces its roots to 1960s mainframes, during which it was a method of logically dividing the mainframes' resources for different applications. Since then, the meaning of the term has evolved to the aforementioned. The term "the cloud" is essentially a metaphor for the Internet] Marketers have further popularized the phrase "in the cloud" to refer to software, platforms and infrastructure that are sold "as a service", i.e...   [tags: hardware, operating system, storage]

Virtualization As A Company Environment Essay

Every generation passing brought along a long different system then the previous generation. As this kept it harder on the user to keep their current system without buying a whole lots of parts that are needed to keep up with the new systems. The computers of that time were only able to run one thing at a time. If you needed multitask you need long scripts to automate everything.

One Physical Server Running Several Virtual Servers: Virtualization Essay

- Introduction:- The idea of virtualization is by and large accepted to have its roots in the mainframe days in the late 1960s and early 1970s, when IBM contributed a ton of time and exertion in creating powerful time-imparting results. Time-imparting alludes to the imparted utilization of machine assets around a huge aggregation of clients, intending to expand the effectiveness of both the clients and the exorbitant workstation assets they impart. This model spoke to a real leap forward in workstation engineering: the expense of giving registering capacity dropped respectably and it got workable for associations, and even people, to utilize a machine without really owning one....   [tags: server farms, computer technology]

- Moore’s law states that “every two years the number of transistors per square inch on integrated circuits has doubled every year since the integrated circuit was invented” (Intel, 2014). This was a term that was coined by Intel co-founder Gordon Moore in 1995 (Webopedia, 2014). This trend has allowed computers to go from large devices, where one computer would take up entire rooms to the computer devices we have now. This same trend can be seen in all parts of computer technology including the networking side of computer hardware....   [tags: software, computers, moore's law]

Essay on Benefits of Virtualization in Computing

- In computing, virtualization means to create a virtual version of a device or resource, such as a server, storage device, or even an operating system where the framework divides the resource into one or more execution environments (, 2014). Virtualization was invented by IBM in the 1960’s (Jansen, 2013). The first operating system that was shipped by IBM that included this software was in 1966 and in 1999, a startup called VMware released a product called VMware workstation. This product worked on regular PCs running Linux or Windows, and was targeted at developers and testers (Jansen, 2013)....   [tags: a virtual version of a device or resource]
