Answer:

Reference

Explanation:

Variables provide reference to the stored data value.

For example:

int i = 0;

Here i is a variable of type int with an initial value of 0. i is a reference to this stored value 0. Now if I want to update the data, I can do so using this reference.

i = 1;

Now the reference is used to manipulate the stored data and change it to 1. In a similar manner all updates to the value can be done using the variable reference.

Answer:

B. False

Explanation:

This is false because for a policy to prevent an infection, there are different processes that takes place. Such processes include detecting the type of infection that enters into the system and then trying to fight it off through the programmed tools.

Detection and reporting of symptoms also helps in the identification of the infection before it is fought.

A final class can't be extended.<br><br> *True<br><br> *False

postnew [5]

Answer:

The answer is True.

Explanation:

The final class cannot be extended because in java final keyword means "no modification". If it is applied to a variable or anything else then that value becomes a constant after that it cannot be modified.So in cases of class if final keyword is used it means that class cannot be extended.

____ is the process of drawing a series of increasingly detailed DFDs, until all functional primitives are identified.

cupoosta [38]

Answer:

a. Leveling

Explanation:

Leveling is also called decomposing.
It is a method to depict more detail in lower-level Data Flow Diagrams
It is the technique to expand or decompose DFDs into more details or levels to extract more information and identify all functional primitives until no further detail is required.
An information system can be comprised of multiple processes. Leveling partitions each process into sub-processes which identifies more details about the process with each level.
0-level DFD: it starts with context diagram which depicts the whole system as a single process e.g. Grading system.
1-level DFD: the context diagram is decomposed in this level. This means a single process is expanded into multiple processes which extracts more details about a process of a system.
2- level DFD: this level decomposes the the process of level 1 going into further details.
This decomposition and expansion continues until no further details are required and all functional primitives are identified.
