Answer:
Virtualization is the technology that is used to create virtual representation and version of the different devices like software, many storage devices and server.
It also help in organize the working framework where the structure isolates the asset into at least one execution situations.
The benefits of using the virtualization on the single machine are:
- The virtualization increased the productivity when it used in the cluster environment.
- We can able to access the different resources faster.
- The data center management is simple while using the virtualization in the cluster environment.
The drawback of using virtualization on single machine are:
- The virtual machine is less efficient as compared to the real machines.
- The virtual machine indirectly access the computer hardware system so that is why it is less efficient and also consume more power to run the system.

Explanation:
An Academic Database deals with the information pertaining to the records of students of an institute. The various fields which can be associated with a student are Name, Unique Identification Number, Marks in various subjects, Grades, Courses Taken and so on. Most of the fields mentioned above have some or other form of validation that is required for the DB to be consistent and follow the basic properties of a database.
One field where range validation can be used is MARKS. In the marks field, the range of marks will be say 0 to 100 and anything below 0 or above 100 must be reported to the database administrator. Another field where we can apply a range validation is AGE in which the range of age allowed could greater than say 10, if it is a college and maximum age could be say 60. Thus, the range check on the AGE field is 10 to 60.
One field where choice validation can be used is GENDER. In the gender field, there could be multiple choices like Male, Female and Others. Thus, out of the available choices we have to select only the available choice and only one choice must be selected where we can apply choice validation. Another field is COURSE, where we can have a list of courses a student can opt for and out of the available courses can select one.
Thus, there are multiple fields where we can apply various types of validation and it is important to explore the area for which the DB has been created understanding all the scenarios and attributes of the problems that are associated with that area.
