Please refer chapter#3 from the textbook attached System architecture is the descriptive representation of the system’s component functions and the communication flows between those components. This definition immediately raises some important questions: What are “components”? Which functions are relevant? What is a communication flow? Answer the questions with an APA-formatted paper (Title page, body and references only). Your response should have a minimum of 500 words. Count the words only in the body of your response, not the references. A table of contents and abstract are not required. A minimum of two references are required. One reference for the book is acceptable but multiple references are allowed. There should be multiple citations within the body of the paper. Note that an in-text citation includes author’s name, year of publication and the page number where the paraphrased material is located.

Introduction
System architecture is a fundamental concept in computer science and information technology, serving as the blueprint for designing and understanding complex systems. It offers a structured overview of a system's components, their functions, and the ways in which they communicate, which is vital for ensuring system efficiency, scalability, and maintainability (Sommerville, 2011, p. 105). This paper explores the core elements of system architecture, focusing on the definition of components, relevant functions, and communication flows within a system, drawing insights from Chapter 3 of the referenced textbook.
Components of a System
Components in a system refer to the individual parts or modules that perform specific functions necessary for the system’s operation (Gelernter, 2014, p. 220). These components can be hardware such as servers, routers, or storage devices, or software modules like databases, user interfaces, and processing units. The identification of components depends on the system’s scope and goals; for example, in a web application, components might include front-end interfaces, back-end servers, and database management systems. Understanding components helps in delineating responsibilities within the system and facilitates modular design (Sommerville, 2011, p. 107).
Relevant Functions in System Architecture
Functions in a system context are the specific operations or activities that components perform to achieve the system's overall objectives (Steven, 2012, p. 89). These functions can include data processing, validation, communication, storage, and retrieval. Relevance of a function is determined by its contribution to system goals—such as ensuring data integrity or enabling user interaction. Functions are crucial in defining how components work together; for example, a database component's function might include storing data securely, while a user interface component’s function is to facilitate interaction with users (Sommerville, 2011, p. 109).
Understanding Communication Flows
Communication flows describe the exchanges of data and control signals between components (TechTarget, 2019). They are essential for enabling coordinated operation within the system. Communication can be synchronous or asynchronous; for example, in a client-server model, requests from clients and responses from servers constitute basic communication flows (Garlan & Shaw, 2012, p. 47). Effective communication flows ensure that components can work collaboratively, exchange necessary information, and respond to system events promptly. The architecture defines protocols, data formats, and timing requirements for these flows, which directly impact system performance and robustness (Sommerville, 2011, p. 113).
Conclusion
In summary, system architecture provides a structured approach to understanding complex systems by defining their components, the functions these components perform, and how they communicate. Components serve as the building blocks, functions ensure the system’s operational goals are met, and communication flows facilitate interaction between parts (Garlan & Shaw, 2012, p. 50). Recognizing and designing these elements effectively is critical for creating systems that are scalable, reliable, and maintainable. The insights from Chapter 3 of the textbook elucidate these core aspects, emphasizing their interdependence and importance in system design.
