Answer:
Information virtualization is the process of representing the abstract data such as numeral number and text into the form of visual which is human can easily understand.
The main challenges faced by the information visualization researchers are:
- The main challenge which are faced by the information virtualization is during the data importing and also cleaning in the system.

- Due to the poor selection of the scale and the coordinate rotation it also lead to the data distortion.
Answer:
See explaination
Explanation:
Here are the steps taken to draw the diagram!
opcode0 and the opcode1 signals are inverted/not to determine the case whether it is 00, 01, 10, 11.
Then they are 'and'ed with the corresponding Zero/lt signal to confirm if the case is true, for eg. zero = 1 if opcode = 00 (beq).
Then all the cases are 'or'ed to get the Branch signal!

Answer:
Logical Data Model
Explanation:
An Entity Relationship Diagram (ERD) is a model or a diagram designed to reveal the relationship between various entities such as people, places, objects, and so on within an institution. Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.
<u>ERD is designed using conceptual data model, logical data model, and physical data model</u>.
The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.
The logical data model is used to illustrate more detailed operational and relational data among the entities. It is more detailed than the conceptual data.
So, the correct answer is logical data model.

Answer:
The function is as follows:
def number_of_pennies(dollars,pennies=0):
return dollars*100+pennies
Explanation:
This defines the function
def number_of_pennies(dollars,pennies=0):
This returns the number of pennies
return dollars*100+pennies
<em>Note that, if the number of pennies is not passed to the function, the function takes it as 0</em>
