A _________ is a set of instructions (program) in Scratch. code

In this era of technology, everyone uses emails for mail and messages. Assume you have also used the

ipn [44]

Answer:

A class may be a structured diagram that describes the structure of the system.

It consists of sophistication name, attributes, methods, and responsibilities.

A mailbox and an email message have certain attributes like, compose, reply, draft, inbox, etc.

Software architecture affects:

Performance, Robustness, Distributability, Maintainability.

Explanation:

See attachment for the Model object classes which may be utilized in the system implementation to represent a mailbox and an email message.

Advantages:

Large-scale reuse Software architecture is vital because it affects the performance, robustness, distributability, and maintainability of a system.

Individual components implement the functional system requirements, but the dominant influence on the non-functional system characteristics is that the system's architecture.

Three advantages of System architecture:

• Stakeholder communication: The architecture may be a high-level presentation of the system which will be used as attention for discussion by a variety of various stakeholders.

• System analysis: making the system architecture explicit at an early stage within the system development requires some analysis.

• Large-scale reuse:

An architectural model may be a compact, manageable description of how a system is organized and the way the components interoperate.

The system architecture is usually an equivalent for systems with similar requirements then can support large-scale software reuse..

NARA [144]

Answer:

A key benefit of inheritance is: an object can have several types, it is type compatible with any of its super classes

Explanation:

Inheritance is one of the fundamental concepts of Object Oriented Programming.
Inheritance allows classes (derived classes) to inherit the methods and properties of a class (base class).
The class or classes that inherits the characteristics from another class is called a derived class, child class or sub class. Derived class can also has it own methods and attributes additionally.
The class whose methods and properties are inherited by the derived class or classes is called a base class, super class or a parent class.
Benefit of inheritance is that inheritance new objects can take properties of existing objects and an object can have many types.
Also a child class can inherit from more than one super classes which is called multiple inheritance.
Multiple inheritance allows a class to implement more than one abstract classes.
An object can have several types. These types can be of an object's own class and also other types which include all classes that a class inherits.
If a variable is declared to be the type of super class then value of that variable can refer to any instance that instantiated from any class that inherits that super class. This means that an object is type compatible with an of its super classes.
