Accessibility is the practice of designing websites, apps, and digital content so people with disabilities can perceive, understand, navigate, and interact with them. It includes support for visual, hearing, motor, speech, and cognitive needs. Accessible design also helps people using mobile devices, slow connections, temporary injuries, or unfamiliar interfaces.
Application Programming Interface is a defined way for software systems to communicate, share data, and request actions. It specifies available operations, required inputs, response formats, and access rules. Developers use an API to connect websites, mobile apps, databases, payment services, maps, and other software without exposing the internal code of each system.
Backend is the server-side part of a website or application that processes requests, applies business rules, stores and retrieves data, manages authentication, and sends results to the frontend. Users usually don't see backend code directly, but the backend controls how features work and how information moves between the interface and databases.
Cascading Style Sheets is a stylesheet language that controls how web pages look and adapt across screens. CSS defines colours, fonts, spacing, layouts, borders, animations, and responsive behaviour. It works with HTML for structure and JavaScript for interactive actions. Allowing developers to change presentation without rewriting page content.
Content Delivery Network is a distributed group of servers that stores and delivers website files from locations closer to users. A Content Delivery Network serves cached images, stylesheets, JavaScript files, videos, and sometimes web pages. This arrangement reduces network distance, improves loading speed, handles traffic surges, and can add protection against some attacks.
Content Management System is software that lets people create, edit, organise, publish, and maintain digital content without changing website code for every update. A Content Management System usually includes an administrative dashboard, content storage, user permissions, templates, media tools, and publishing controls. WordPress, Drupal, and Joomla are common examples.
Conversion Rate is the percentage of visitors or users who complete a desired action, such as purchasing a product, submitting a form, booking an appointment, or signing up for an account. It's calculated by dividing completed conversions by total eligible interactions and multiplying the result by 100.
Domain Name System is the internet naming system that translates human-readable domain names, such as example.com, into numerical IP addresses used by web servers. DNS also stores records for email delivery, security checks, and other services. It lets browsers and applications find the correct online destination without requiring people to remember IP addresses.
Favicon is a small image that identifies a website or web page in browser tabs, bookmarks, history lists, and search results. A favicon usually appears as a square ICO, PNG, or SVG file linked from a page’s HTML. The image gives users a quick visual cue for recognizing and returning to a site.
Frontend is the part of a website or application that users see and interact with in a browser or app. It includes page structure, visual styling, navigation, forms, buttons, animations, and client-side behaviour. Frontend development commonly uses HTML, CSS, and JavaScript to turn design and data into usable digital experiences.
HTTP is the application-layer protocol that lets web browsers, servers, and other systems exchange resources such as HTML pages, images, stylesheets, scripts, and API data. A client sends a request, and a server returns a response with a status code, headers, and optional content. HTTP forms the foundation of ordinary web communication.
Hypertext Transfer Protocol is the application-layer protocol that lets web browsers, servers, and APIs exchange requests and responses across a network. It defines methods such as GET and POST, status codes such as 200 and 404, headers, and message formats. HTTP commonly runs over TCP, while HTTPS adds encryption through TLS.
JavaScript is a high-level programming language that adds behaviour and interactivity to websites and web applications. Browsers run JavaScript to respond to clicks, validate forms, update page content, communicate with servers, and create dynamic interfaces.
Landing Page is a focused web page created for a specific marketing, advertising, or search campaign. It usually supports one primary action, such as submitting a form, booking a consultation, downloading a guide, or buying a product. Unlike a general website page, it limits distractions and connects the visitor’s intent with a measurable conversion.
Lazy Loading is a web speed technique that delays loading nonessential resources until they're likely to be needed. A browser may wait to fetch below-the-fold images, videos, scripts, or interface components until a user approaches them. This approach reduces initial page weight, saves network data, and can improve the first view of a page.
MFA is a security method that requires two or more different types of evidence before granting access to an account or system. Evidence may include something you know, something you've, or something you're. Passwords, authenticator apps, security keys, and fingerprints are common MFA factors.
Mobile-First Design is a web design approach that starts with the smallest practical screen and then adds features for larger screens. Designers first plan content, navigation, layout, touch controls, and speed for mobile users. The design then expands through responsive layouts rather than shrinking a desktop page to fit a phone.
Page Speed is the time a web page takes to display its content and respond to user actions after a request begins. It depends on hosting, network conditions, file sizes, browser processing, and code efficiency. Developers assess it with loading metrics such as Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift.
Progressive Web App is a website that uses modern web technologies to provide app-like features, including offline access, installation, notifications, and fast loading. It runs through a web browser but can appear on a device home screen. A service worker manages background tasks and cached resources while HTTPS protects data exchanged with the site.
Responsive Design is a web design method that lets a website adjust its layout, text, images, and controls to fit different screen sizes and orientations. It uses flexible grids, scalable media, and CSS media queries so pages remain usable on phones, tablets, laptops, and desktop monitors without requiring separate site versions.
REST API is an application programming interface that lets software exchange data over HTTP through identifiable resources and standard actions such as GET, POST, PUT, and DELETE. A REST API usually sends data in JSON and remains stateless, so each request contains the information needed to process it without relying on earlier requests.
Secure Sockets Layer is a former security protocol that encrypted data exchanged between a web browser and a server. SSL helped protect passwords, payment details, and other private information from interception. Modern websites use Transport Layer Security, or TLS, which replaced SSL and provides the encryption behind HTTPS connections.
Sitemap is a file or web page that lists important URLs on a website and provides information about their organisation, update timing, and content type. XML sitemaps help search engine crawlers discover pages. While HTML sitemaps help people navigate site content. A sitemap doesn't guarantee indexing or higher rankings.
Simple Data is a standardized format that labels information on a web page so search engines and software can interpret it consistently. It can describe products, articles, events, organisations, reviews, recipes, and other entities. Common formats include JSON-LD, Microdata, and RDFa, with Schema.org vocabulary providing widely used definitions.
User Experience is the overall impression and response a person has while using a product, service, or digital interface. It includes ease of use, accessibility, efficiency, trust, and satisfaction across the complete journey, from the first interaction to task completion. User Experience covers both functional speed and emotional response.
User Interface is the visual and interactive layer through which people control a website, app, or digital system. It includes screens, menus, buttons, forms, icons, text, colours, and feedback messages. A well-designed interface helps users understand available actions, complete tasks, recover from errors, and access information across devices.
UX is the overall experience a person has while using a product, website, app, or service. It includes ease of use, accessibility, speed, clarity, trust, and emotional response. UX covers research, planning, interaction design, content, testing, and improvement across the complete user journey, not only visual appearance.
Web Content Accessibility Guidelines is an international standard for making websites and digital content usable by people with disabilities. WCAG defines testable recommendations for vision, hearing, movement, and cognitive access. The guidelines cover text alternatives, keyboard access, contrast, captions, page structure, forms, and compatibility with assistive technologies such as screen readers.
