Technology, explained clearly. Find a term, choose a letter or narrow the topic. Definitions include sources and their review date.
Terms 685 / 685
Web application firewall
A firewall analysing application traffic, especially HTTP, using security rules. It mitigates some attacks but does not replace vulnerability fixes or application authorisation.
Definition and sourcesWeb crawler
Software automatically visiting web addresses and inspecting resources. A crawl does not by itself mean indexing or inclusion in results.
Definition and sourcesWeb developer
A person developing websites and web applications, specialising in interfaces, server-side work or both. Responsibilities depend on the team and product rather than one compulsory list of languages.
Definition and sourcesWeb page
A document or view available at a web address. A website comprises related pages; applications may generate many views from one template.
Definition and sourcesWeb3
A collective term for internet visions and projects using blockchain, tokens and decentralised applications. It is not one standard or a completed replacement of today's web. Evaluate decentralisation and security for each solution.
Definition and sourcesWebAssembly
A code format and execution model for compiled modules. It can run inside and outside browsers; permissions depend on the host environment.
Definition and sourcesWebflow
A visual website-design and publishing platform. CMS, hosting and export capabilities depend on the plan; visual editing does not remove testing needs.
Definition and sourcesWebhooks
Notifications sent to an HTTP endpoint after events such as payments. Receivers should verify authenticity and handle retries and duplicates. Webhooks guarantee neither immediate nor exactly-once delivery.
Definition and sourcesWebinar
An online presentation or meeting for an audience. It needs interaction, accessibility and recording planning; the format alone does not ensure valuable training.
Definition and sourcesWebmail
A browser interface for email. It is not a separate email-delivery protocol; security depends on authentication and session protection among other controls.
Definition and sourcesWebmaster
A traditional term for someone maintaining a website's operation, updates and publishing. Scope varies by organisation. Larger teams may divide those responsibilities among administrators, developers and editors.
Definition and sourcesWebP
An image format supporting lossy and lossless compression and transparency. Choose settings for the content; the extension alone does not guarantee small files.
Definition and sourceswebpack
A tool bundling application dependencies and assets. Configuration affects code splitting, caching and output size; bundling does not automatically fix architecture.
Definition and sourcesWebsite template
A page-presentation pattern populated with content. Choosing a template does not automatically ensure quality content, accessibility, SEO or secure configuration.
Definition and sourcesWhite paper
A document explaining a project's problem, assumptions and proposed solution. Blockchain papers often describe network and token mechanics. A white paper alone does not establish code quality, security or the authors' reliability.
Definition and sourcesWhite-hat SEO
Search optimisation following search-engine policies through useful content and sound websites. The label guarantees no ranking and does not replace reviewing actual practices.
Definition and sourcesWHMCS
A platform automating hosting sales and service operations, including billing and accounts. Integrations can have broad permissions and need protected secrets and updates.
Definition and sourcesWHOIS and RDAP
Mechanisms querying internet-resource registration data. RDAP replaces some WHOIS uses; public-data coverage depends on registry and privacy rules.
Definition and sourcesWidget
A self-contained interface or content element embedded in a larger view. CMS widgets may have settings and placement; third-party ones can add dependencies and tracking.
Definition and sourcesWildcard DNS
Records using a * label to synthesise answers for certain missing names. They do not simply match every address or replace wildcard certificates.
Definition and sourcesWireframe
A simplified outline of interface structure and hierarchy. It supports layout discussion before visual refinement and need not reproduce final imagery or interactions.
Definition and sourcesWooCommerce
An open-source commerce platform built around WordPress for products, orders and sales, with extensions adding features. Store costs also include hosting, maintenance and potentially paid extensions.
Definition and sourcesWordPress
A community-developed open-source content-management system. Themes and plugins adapt the website. WordPress.org is the software project; WordPress.com is a separate hosting service. Free code does not mean cost-free operation.
