Q10) Define the concept of Hypervisors
The hypervisor is referred to a virtual system manager that aids multiple operating systems to utilize one hardware hosting system. This has simplified the overall operating procedure and provided the business industry with several facilities.
Q11) Explain the term virtualization
Virtualization is one of the most significant innovations in technology. It is a technology that allows converts hardware into a virtual form or software. It is broadly used in today’s age and has been a significant segment of the Information technology industry. The technique of virtualization is relevant to Denodo as it mainly aims to convert conventional information and make it much more ascendable.
Q12) Explain the execution of ROI in the Denodo platform.
The ROI plays a vital role in the particular platform as it possesses a massive reduction in areas like storage, development, software, hardware, and price of maintenance. It is one of the most significant advantages of the DV platform.
Q13) What is the primary format of tackling information quality requirements of DV?
The Denodo interface is suffused with in-built techniques and tools provides ample amount of leverages to users. The tools include the facilities of information pairing, transforming, editing. The mentioned areas are solely stationed on the regulations of ‘apply-on-the-fly.’ The trend of tackling involves detecting or tracking information sources which has made the entire operation much simpler for all categories of users.
Q14) Elaborate the relationship between data virtualization and the IT industry.
Data virtualization plays a magnificent role in redefining the norms and trends of the IT industry. The high-end and futuristic features of the Denodo are equipping the information technology domain with ample agility and dependability in the recent years. The BI techniques and tools along with the advanced virtualization technology have facilitated the IT industry in several forms and under multiple names but the most significant and only aim is to improve and advance data management and advancement in every possible form.
Q15) How Denodo allows the assimilation of Web data
The Internet is one of the most versatile, vast and rapidly growing information sources. Unlike other approaches available in the market stack, the Denodo consists of semantic techniques, internet automation, and unformed information, which are often efficiently used to add instant value to a business.
Q16) Name the top proficiencies of Denodo
There are several capabilities of Denodo but some of the key capacities include,
Q17) How does the process help in obtaining data value in a short span of time
First of all, the operation and navigation of data are highly flexible in the particular process as it does not require a physical storage or allocating location neither does it need data transfer. The Denodo lets the user get access to real-time information and data and allows dynamic operational leverages at the same time. It is one of the top-most reasons behind business owners and industrialists using the same as their right hands in making the most out of the data.
Q18) Does the particular process aid in sound and agile decision making and how?

Q21) State the differences between whole-virtualization and Para-virtualization
Both of the above mentioned categorize tied to one single pole that is the hardware virtualization. In case of full virtualization, the VMS are heedless of the fact that they exist in a virtualized space. Hence the guest VMS interacts to the accelerated apparatus developed by the hosting although the VMS considers the same to be original hardware.
On the other hand, the process of Para-virtualization involves absolute alertness from the guest VMS that it exists in a virtualized environment. Henceforth, in case of any concern or need for resources, it straightway places command to the hosting system.
