System Architecture: Describe the system architecture. Specifically, be sure to address the corporate organization and culture,
alekssr [168]

Answer:

Explanation:

In information technology, architecture plays a major role in the aspects of business modernization, IT transformation, software development, as well as other major initiatives within the enterprise. IT architecture is used to implement an efficient, flexible, and high quality technology solution for a business problem, and is classified into three different categories: enterprise architecture, solution architecture and system architecture. Each of these classifications varies in their implementation and design, depending on the contextual business scope, organization structure, and corporate culture.

Architecture Level

Architecture level represents the scope boundary and granularity of details the architectural activity should take, based on organization hierarchy and communication audience.

  • Enterprise Architecture (Company level) aligns technological strategies and execution plans with business visions and objectives by providing architectural oversight and guidance. Enterprise architecture also drives consolidation, reuse, and economy of scale by addressing company-wide goals in a holistic way across all IT projects.
  • Solution Architecture (Department level) models a solution vision that defines the IT systems, business processes and reusable services for a specific business unit, spanning across business and technology architectures.
  • System Architecture (Team level) defines the structure of an information system in terms of various subsystem components and their relationships with internal and external systems. System architecture focuses on application, data, and technology, and is called software architecture in some organizations.

Before making decision regarding system architecture the designer must consider the following points:

  • Corporate organization and culture: System architecture must study day-to-day functions of business and users in order to understand corporate organization and culture. This will help in focusing on operational feasibility which will help in deciding other checklist items.
  • Enterprise resource planning (ERP): Most of the organization use ERP software these days and it is important for the analyst to understand the compatibility of the ERP which is used to the proposed system.
  • Total cost of ownership (TCO): System analyst must try to get solutions of different questions which helps in finding initial cost and cost which may add up during the development, which is total cost of ownership. This is most important at this will determine total cost and budget of system.
  • Scalability: Determining system ability to expand or downsize according to business requirements.
  • Security: What security system and policy needs to be implemented.

The remove() method in the Queue interface ________. Group of answer choices retrieves, but does not remove, the head of this qu
salantis [7]
<h2>Question:</h2>

The remove() method in the Queue interface ________.

A. retrieves, but does not remove, the head of this queue, returning null if this queue is empty

B. retrieves and removes the head of this queue, or null if this queue is empty

 

C. retrieves, but does not remove, the head of this queue, throwing an exception if this queue is empty

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

<h2>Answer:</h2>

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

<h2>Explanation:</h2>

In Java, the Queue interface is found in the java.util package and inherits from the Collection interface. It is used to store elements which are processed in the order in which they are inserted. This means that the first element will be processed first.

The Queue interface has many methods. Some of them are;

i. add(): allows elements to be added to the queue.

ii. remove(): retrieves and removes elements from the head of the queue. The head of the queue points to the first element of the queue. If the queue is empty, the remove() method throws an exception called the <em>NoSuchElementException</em>

<em />

iii. poll(): retrieves and removes the element at the head of the queue. Unlike the remove() method, if the queue is empty, a <em>null </em>is returned.

iv. peek(): retrieves but does not remove the element at the head of the queue. Just like the poll() method, a <em>null</em> is returned if the queue is empty.

The class ________ is the portion of a class that is visible to the application's programmer.
Lady_Fox [76]

The correct option to this question is class interface.

The class interface is the portion of a class that is visible to the application’s programmer. Class interfaces mean implementation of public methods of the class. These class interfaces of the class are easily visible to the application’s program either the one who is developing the application program or the one who is reading the application’s code.

Class interface can be seen by the other classes as its public face. Class interfaces separate the class’s implementation and its interaction with other classes. That way the implementation of the class can be modified easily without being known by other classes. Basically, the programmer who is developing the program, all the portions of the programm is visible to that programmer.

For example, the class is written below:

class class-name

{

private members;

public method()

{

//method defination

}

}

when the class object is created, the code of the object to the programmer is visible.

<u>While the other options are incorrect:</u>

  • Form: the form is used to collect information from the user. It can be build using front-end development tools
  • Design: Design is a term used in computer or software engineering to make something from scratch or beginning. It can be  methodologies, standards, or techniques etc.
  • Control: Control is the mechanism or a term used in software development to control the program or execution of the program.
