Answer: C. Differential backup
Explanation: There are several ways od ensuring the preservation and storage of data even cases of disaster, one of such ways is data data mirroring which allows data to be replicated or copied in real time and several backup options. In cases where there there is need to restore a server, the warm recovery site provides a data or disaster recovery option used to mitigate the effect of data loss on organization. In the absence of data mirroring, differential backup option, provides the quickest recovery option as it only requires changes in the data stored after the last full backup. These speed experieced should be expected due to the relatively low data been dealt with rather than the entire data.
The answer is : variables
When viewing data entered into a spreadsheet, the columns identify Variable. The variables later can be used on a formula to help you process any sort of data that is implemented within excels' formula system
Answer:
False
Explanation:
An abstract class is a class declared abstract — it may or may not include abstract techniques. It is not possible to instantiate abstract classes, but they can be sub-classed.
<u></u>
<u>Abstract method declaration</u>
abstract void moveTo(double X, double Y);
Usually the subclass offers solutions for all of the abstract techniques in its parent class when an abstract class is sub-classed. If not, however, the subclass must be declared abstract as well.
<u>Example</u>
public abstract class GraphicObject {
// declaring fields
// declaring non-abstract methods
abstract void draw();
}
