From how I interpret it, it means that you can use X amount of megabytes or gigabytes within the billing cycle. For example, if you went with $100/2 months for 10GB of data, you would pay $100 every 2 months, and within those 2 months you would be able to use 10 gigabytes of data. It looks like the average smartphone user uses about 3GB of data per month, but you'll have to gauge it based on what you normally use.

Answer and Explanation:
The ways in which a layered pattern make use of encapsulation and abstraction are as follows:
- This framework lays its focus mainly on the bundling of related functionalities inside an application into different layer that are vertically stacked over one another.
- Functionality in between each layer is related by common function or role.
- Communication in between the layers is clear and exact and is coupled loosely.
- Providing a layered structure to the application indirectly supports its maintainability and flexibility.
Encapsulation:
Since, features like data type, properties, methods or implementation while designing are not exposed at the boundary of the layer thus No assumptions are required for these features.
Abstraction:
The layered framework abstracts the entire system's view and provides adequate details for better understanding of the roles of each layer individually and the relation that exist between these layers.
Answer:
The best choice in this situation is the Router.
Explanation:
A router is hardware networking device that receive, analyze and forwards data packets to another network or between computer networks. It assists to direct data on the internet and its connected to at least two networks. Router can also be a gate way that is an interface or connection between two or more networks.
Answer:
B. string -> (int -> int)
Explanation:
We are going to perform comparison operations '->'. It is important to notice that the comparison operation gives us a bool value (True or False) and the comparison operation is legal if and only if the data types to be compared are the same.
Example:
int(4)->int(5) False
int(4)->int(4) True
int(4)->string(4) Error, data types don't match
For this reason:
- A. Is legal because float -> float evaluates to True, True is a boolean value and bool -> bool is legal because both are the same data type.
- B. Is illegal because int -> int evaluates to True, True is a boolean value and string is not a boolean (string -> bool).
- C. Is legal because int is the same type than int.
- D. Is legal because the list is the same type than list regardless it's content.
Note:
The operations inside parentheses are evaluated first.
List is a type by itself regardless of its content.
