Rails follows the Model-View-Controller (MVC) architectural pattern, emphasizing convention over configuration and providing a set of conventions and tools for rapid web application development.
Scalability	Scalability is the ability of a system, software application, or infrastructure to handle increasing workloads and growing demands. It involves designing and implementing systems that can be easily expanded, adapted, or optimized to accommodate higher traffic, larger datasets, or additional users without performance degradation.
Search Engine Optimization (SEO)	Search Engine Optimization (SEO) is the practice of improving a website’s visibility and ranking in search engine results pages. SEO techniques involve optimizing website content, structure, keywords, and other factors to increase organic traffic, enhance user experience, and gain higher search engine rankings.
Serverless Architecture	Serverless architecture is a cloud computing model where cloud providers manage and allocate computing resources dynamically. Developers focus on writing and deploying individual functions or services, without the need to manage servers or infrastructure. Serverless architecture enables scalability and cost optimization.
Single Page Application (SPA)	A Single Page Application (SPA) is a web application that dynamically updates content and interactions on a single web page, eliminating the need for page reloads or navigation to different pages. SPAs provide a seamless user experience, often using JavaScript frameworks like Angular or React for client-side rendering.
Software Development Kit (SDK)	A Software Development Kit (SDK) is a collection of tools, libraries, documentation, and resources that developers use to build software applications for a specific platform, framework, or programming language. SDKs provide prebuilt components, APIs, and guidelines to streamline application development.
Software Engineering	Software engineering is a discipline that applies engineering principles and practices to the development, operation, and maintenance of software systems. It involves systematic approaches, methodologies, and tools to design, build, test, and evolve software, ensuring quality, reliability, and efficiency.
Static Typing	Static typing is a type-checking method where variable types are checked during compile-time or before the code is executed. It requires explicit type declarations and helps catch type-related errors early in the development process, improving code quality and reducing potential runtime issues.
Test Coverage	Test coverage is a measure of the extent to which source code is tested by a set of test cases. It quantifies the percentage of code that is executed or covered by tests. Test coverage analysis helps identify areas of code that are not adequately tested, enabling developers to improve test effectiveness and reliability.
Token	In the context of programming and security, a token is a piece of data used to represent authentication, authorization, or session information. Tokens are often used in token-based authentication systems, where they provide a secure and stateless way to verify and authorize access to protected resources.
UI/UX	UI/UX, short for User Interface and User Experience, refers to the design and interaction elements of a software application or website that directly impact how users perceive and interact with the system. UI/UX design focuses on usability, accessibility, aesthetics, and overall user satisfaction.
Unit Testing	Unit testing is a software testing technique where individual units or components of a program are tested in isolation. It involves writing and executing test cases for each unit to verify its correctness, functionality, and behavior. Unit testing helps identify bugs early and facilitates code maintainability.
Usability Testing	Usability testing is a user-centered testing approach that evaluates the ease of use and effectiveness of a software application or website by observing users performing specific tasks. It helps identify usability issues, gather user feedback, and improve the user interface and overall user experience.
