The answer is C: Operating System Virtualization
Answer:
The active directory (AD)
Explanation:
Included in the operating system of Windows server is a primary feature called Active Directory which essentially manages a centralized database containing user account and security information such as password.
The AD is created by Microsoft and allows users (typically admins) to manage network and IT resources and application data of a system running the Windows operating system. AD can be used to create users, authenticate users and authorize users to be able to access servers and applications on the system.
The correct answer: Data independence
Data independence<span> is the type of </span>data<span> transparency that matters for a centralised DBMS. It refers to the immunity of user applications to changes made in the definition and organization of </span>data<span>. Physical </span>data independence<span> deals with hiding the details of the storage structure from user applications.
</span>
The logical<span> structure of the data is known as the 'schema definition'. In general, if a user application operates on a subset of the </span>attributes<span> of a </span>relation<span>, it should not be affected later when new attributes are added to the same relation. Logical data independence indicates that the conceptual schema can be changed without affecting the existing schemas.
</span>
<span>The physical structure of the data is referred to as "physical data description". Physical data independence deals with hiding the details of the storage structure from user applications. The application should not be involved with these issues since, conceptually, there is no difference in the operations carried out against the data.</span>
EOCS can be fixed locations, temporary facilities, or virtual structures with staff participating remotely is a true statement.
<h3>What is the Emergency Operations Centers (EOC)?</h3>
Emergency Operations Centers is known to be part of the four NIMS Command and Coordination structures as the EOCs are known to be used in an off site locations where staff are gotten from a lot of agencies that come together to address some imminent kind of threats and hazards.
Therefore saying that EOCS can be fixed locations, temporary facilities, or virtual structures with staff participating remotely is a true statement.

Answer:
A and B have different output:
A output will be 1
B output will be 123
Explanation:
A
X = 0
do x < 3
x = x+1
print x
while
B
X = 0
do x = x+ 1
print x
while x < 3
For statement A the condition statement which suppose to be after "while" is not set therefore the value of x will be printed.
For statement B the condition statement is set "x < 3" in front of "while" thereby result in iteration until the condition is false.
Statement A output will be 1
Statement B output will be 123
