Many companies are undergoing server virtualization. This is the concept of putting multiple“virtual” servers onto one physical device. The payoffs can be significant: fewer servers, lesselectricity, less generated heat, less air conditioning, less infrastructure and administrationcosts, increased flexibility, less physical presence (that is, smaller server rooms), fastermaintenance of servers, and more. There are costs, of course, such as licensing thevirtualization software, labour costs in establishing the virtual servers onto a physical device,labour costs in updating tables, and access. But determining the return on investment can be achallenge. Some companies have lost money on server virtualization, while most would saythat they have gained a positive return on investment but have not really quantified theresults.(a) How might a company really determine the return on investment for server virtualization?

Virtualization is the most efficient method there is for running several operating systems on a single piece of hardware. No of how you feel about the present state of affairs, what is the most effective approach to summarise the situation as it now stands?

When feasible, what are the upsides of prioritizing the I/O queue as the place where processes would be executed? If the I/O connection suddenly goes down, what do you expect to happen? How would this affect the fastest possible CPU burst rate? I'm not quite sure I get what you're getting at here.

A modem computer needs memory (RAM and ROM) to function. Memory is where programmes and data are stored when the processor is actively using them. Because memory is linked to the processor, moving instructions and data into and out of the processor is incredibly fast. In a multiprogramming computer, the operating system occupies a portion of memory, while the remainder is shared by several processes. As a result, memory management is required to split memory across different processes. As an engineer in the R&D department, write a newsletter about "Memory Management in Personal Computing". The newsletter should have the following points: a) Definition of memory management b) Explanation of three reasons for applying memory management in personal computing. c) Explanation of four memory management techniques d) References - Use a referencing style that complies with the APA style. e) Page of Turnitin Originality report with the percentage of similarity index

Virtualization is the most time- and resource-effective approach of installing and operating several operating systems (OSes) on a single machine. What do you think is the most accurate approach to summarise the current situation, regardless of how you feel about it?

Malware uses various techniques to covertly execute code on systems. One such technique is DLL injection. DLL injection involves causing code to execute within the address space of some other process. This is accomplished by forcing the targeted program to load a DLL. Why are malware hiding techniques like DLL injection successful? Shouldn't the operating system have built-in controls to prevent DLL injection? Shouldn't anti-malware software be able to detect and prevent DLL injection 100 percent of the time?

How can CPU Scheduling improve an operating system's overall performance? Be particular in your response by taking into account OS resources such as CPU, RAM, I/O devices, and so on.

Describe hardware virtualization extensions (e.g., Intel VT-x, AMD-V) and their impact on virtualization performance.

Can someone help me with the following, it's revision for an exam I'm doing. If your explaining it could you please provide detailed steps of why you did what you did so I know how to do it if it comes up in the real thing!  Thank you so much! :)   An IT administrator is interested in studying server traffic. He believes that the time (inminutes) between requests being sent to a server can be well modelled using a Weibulldistribution with parameters α = 2 and β = 1 b) The median arrival time is defined to be the time for which the probability of beingless than this value is 0.5. Calculate the median time between requests

Multitasking makes it simple for you to flip between the several applications you have open. Is it possible to run several operating systems on the same computer? That begs the question: yes or no? What alternatives are there for you to consider in the event that this is the case?
