Web Application Structure: Back-end Architecture

What is back-end architecture in web applications?

• The front-end programming languages and frameworks

• The visual design and layout of the website

• Server-side structure and technologies used to handle the logic, database interactions, and other behind-the-scenes operations

• The process of optimizing a website for search engines

What are the key components of back-end architecture?

• CSS, HTML, JavaScript

• user interface, client-side scripting, web design

• server, database, application logic, and APIs

• front-end components, server, database

Explain the role of databases in back-end architecture.

• Databases are used for front-end development

• Databases have no role in back-end architecture

• Databases are only used for storing images

• Databases store and manage data for web applications.

What is the difference between monolithic and microservices architecture in the back-end?

• Monolithic architecture is a single unified unit, while microservices architecture is composed of small, independent services.

• There is no difference between monolithic and microservices architecture

• Monolithic architecture is made up of small, independent services

• Microservices architecture is a single unified unit

Discuss the importance of scalability in back-end architecture.

• Scalability is not important in back-end architecture

• Scalability only affects the front-end of the system

• Scalability is only necessary for small-scale applications

• Scalability allows the system to handle increased workload and growth without sacrificing performance or reliability.

Explain the concept of server-side rendering in back-end architecture.

• Server-side rendering is the process of rendering the initial view of a web page on the database server.

• Server-side rendering is the process of rendering the initial view of a web page on the server and sending the fully rendered page to the client's browser.

• Server-side rendering is the process of rendering the initial view of a web page on the client's browser.

• Server-side rendering is the process of rendering the initial view of a web page on the front-end server.

What are the common programming languages used in back-end development?

• Java, Python, Ruby, PHP, C#, Node.js

• HTML, CSS, JavaScript

• C++, Swift, Objective-C

• Perl, R, TypeScript

Discuss the role of APIs in back-end architecture.

• APIs are only used for data storage in back-end systems

• APIs play a crucial role in enabling communication and data exchange between the front-end and back-end systems.

• APIs are only used for front-end development

• APIs are not necessary for back-end architecture

Explain the concept of load balancing in the context of back-end architecture.

• Load balancing helps distribute incoming network traffic across multiple servers to optimize resource utilization and prevent any single server from becoming overwhelmed or a single point of failure.

• Load balancing refers to the process of adding more servers to handle increased traffic without any optimization.

• Load balancing is the process of evenly distributing the weight of a server to ensure it doesn't collapse under pressure.

• Load balancing is the practice of shutting down servers to reduce the load on the remaining servers.

What are the best practices for securing back-end architecture?

• Using weak passwords and no encryption

• Never updating the software or conducting security audits

• Leaving the back-end open for public access

• Implementing strong authentication and authorization mechanisms, encryption for data at rest and in transit, regular software updates and patches, and conducting regular security audits and testing.
