SUBJECT: Expanded Definition of Virtualization
Introduction
The scientific term I decided to write this expanded definition was Virtualization. I will be discussing virtualization on desktop computers and laptops. The following will define the term in a way that someone who isn’t familiar with the technology can understand and how it can also be used in their everyday life. As this type of technology is now more available to the public, people have yet realized the possibilities that can be produced. Such as being an owner of a company you can use this resource to increase your workflow or minimize cost on resources for your workers.
Definition
“Virtualization has been a part of the computing landscape for nearly half a century. In the 1960s and 1970s, IBM developed the Control Program/ Cambridge Monitor System (CP/CMS) which led into VM/370. These systems let each user run what appeared to be an isolated system, but all within one timeshared computing environment.”
When we think about virtualization the term virtual comes to mind. In the field of technology we want to bring out the most we can possible with little hardware in physical space. Throughout the years the technology has advanced that not only enterprise grade hardware was the only ones capable of utilizing the technology but also the consumer market now has a chance to provide the tech. This is due to chips providing more cores allowing more power for the average person as technology and demand increases.
Virtualization can go beyond software as hardware virtualization has been more effective due to advances in technology allowing hardware sharing. Including the huge boost in cloud services this feature has be enabled in many devices as long as its connected to the internet you can have access to many services by different distributors.
Context
As of the beginning of the year 2020 the COVID-19 pandemic as created a lot of educational struggles for many students of all grades including college. This has lead to the start of remote learning as students couldn’t go physically. However resources had to be shared in some form of being accessible by everyone no matter the current situation.
“At present, virtualization and virtualization technology represent a powerful tool for the consolidation and simplification of vast hardware and software structures administration. Their potential is extensive, considering their employment; they are used in numerous branches and fields. It is therefore logical that the issue of virtualization technology is becoming a priority for educational institutions not only in terms of their internal information systems, but also as a means of solving particular educational issues regarding advanced administration and operation of information systems.”
In the article “Virtualization for computer networking skills development in a distance learning environment” this is presented as before the pandemic Virtualization has been proven to be a strong tool for such case, to remotely share resources to people around the world with minimal space as it can be hardware sharing and software sharing through the cloud. Organizations have services established.
“The technology itself is not only a matter of server virtualization (or client workstations), as individual applications may be virtualized as well.”
The quote is from Milan Klement’s article “Models of integration of virtualization in education: Virtualization technology and possibilities of its use in education“ As the article includes details on how what type of virtualization an organization can set up for students and what tools the faculty could expect to use to provide more insight in providing low level IT skills to people who wouldn’t need such advanced tools.
Working Definition
Virtualization is a form of technology enhancement that has been around for decades and has enabled a multitude of features such as software sharing and also hardware sharing, minimizing the amount of physical hardware needed to connect multiple people to a single device.

Subject: 500-word Summary
The paper is a summary of a series of benchmark tests between two major processor companies putting their high-end chips to their test. Over the years Intel and Advanced Micro Devices have been on the leading edge of competition throughout the years while also collaborating. Although there are speculations on which side surfaced the new technology first the first breakthrough would be when Advanced Micro Devices settled with 64 bits computing on the x86 instruction set which was then purchased by Intel. Since then, each generation of processors have been researched and developed but have we reached a limit on microprocessors. It has been difficult to fit more transistors on a die as there is a physical limit, this is following Moore’s law as we noticed there will be a limit on transistors we can fit in a single integrated circuit. This is due to the material that these processors are made in which is silicon.
Advanced Micro Devices (AMD) have been on the CPU market against Intel and in recent events AMD has released the Zen microcomputer architecture, in which the Ryzen processors have been established. AMD has reached the same number of physical cores they can fit in a package as Intel. They were tested each in benchmark programs to put the chips to the most output. Both chips utilize the same x86 instruction set and are manufactured with 14nm transistors. Ryzen has been equipped with more cache than its Intel counterpart. Ryzen processors are loaded with less output ports on the scheduler which is the creating a functioning system of setting processes in order of execution and priority. While the Intel chip has more outputs built in, its scheduler is unidentified and no information about it has been available. The Intel chip has a function called turbo-boost which increases the clock speed at a certain threshold unlike the Ryzen chip which is locked.
Software that was used was SPEC a benchmark testing program with multiple test scenarios that can exhibit real life stimulations of utilizing CPU power. The series of tests consists of how fast the CPU can process the instructions as if it were in a real-life simulation. Both test benches utilized the same Linux OS (Ubuntu) and had the same amount of DDR4 RAM which was 16GB. The test results show that both excel performance however the intel chip was consuming more energy than Ryzen. Multithreaded stimulations were difficult to properly exam due to synchronization. After tests it shows that Ryzen performs better in multi-threaded tasks than the Intel’s Core CPU and consumes more energy. In conclusion, Intel’s 8th gen i7 processor outperformed in tests but consumed more energy than Ryzen. Both chips performed the same but there are differences in the way they are manufactured
