Technology, explained clearly. Find a term, choose a letter or narrow the topic. Definitions include sources and their review date.
A general HTTP status signalling an unexpected server-side problem. It does not identify a specific cause. Diagnosis requires safe inspection of logs and configuration; updating PHP at random is not a universal fix.
Definition and sourcesAn HTTP status indicating temporary unavailability, such as overload or maintenance. Retry-After can suggest when the client should retry.
Definition and sourcesAn HTTP status indicating that the server does not support, or refuses to support, the major protocol version used in the request. It concerns HTTP, not the browser version or a general network outage.
Definition and sourcesHeaders controlling selected browser protections, such as CSP and HSTS. They need application-specific configuration; their presence does not prove absence of vulnerabilities.
Definition and sourcesA browser policy enforcing HTTPS for a host. Long lifetimes and subdomain coverage should be enabled only after the full scope is ready.
Definition and sourcesAn HTTP version with binary framing and multiple streams per connection. It can reduce communication overhead but does not solve application-performance problems.
Definition and sourcesAn HTTP version using QUIC rather than TCP. It changes transport and connection-establishment behaviour; benefits depend on network, client and infrastructure.
Definition and sourcesHTTP carried over a TLS-protected connection. It protects transmission confidentiality and integrity and supports server authentication. A padlock does not establish the owner's honesty or protect against every application defect.
Definition and sourcesAn architecture combining private or on-premises environments with public cloud. Integration, management and data flow matter, not merely having two providers.
Definition and sourcesA backup protected against changes or deletion for a defined retention period and policy. Immutability does not replace permission separation or restoration tests.
Definition and sourcesA historical name for video ads inviting selection from feeds or results. Google's documentation uses the name in-feed video ads.
Definition and sourcesAds shown before, during or after video content. Skipping options and charging rules depend on format and platform.
Definition and sourcesA brand's cooperation with a creator connected to an audience. Assess audience fit, advertising disclosure and outcomes, not just follower counts.
Definition and sourcesA visual presentation of information or data explaining relationships. It needs clear sources, honest proportions and a textual alternative for nonvisual access.
Definition and sourcesA service model supplying infrastructure such as virtual machines, networks and storage. Customers typically remain responsible for operating systems and applications.
Definition and sourcesDescribing infrastructure in versioned files rather than only manual configuration. It supports repeatability and review; secrets and state require separate protection.
Definition and sourcesMeta's platform for sharing and communicating through photos and video. Reach depends on features and recommendation systems; follower counts do not guarantee delivery.
Definition and sourcesInstagram's short-lived publishing format, normally visible for 24 hours unless highlighted. Visibility and archiving depend on account settings.
Definition and sourcesA tool automating application installation and management on hosting. Automated setup does not remove responsibility for updates, configuration and backups.
Definition and sourcesTests of cooperation between components, such as application and database. They check contracts not covered by an isolated single-function test.
Definition and sourcesA responsiveness metric describing interaction latency until the next visual update. It covers more stages than historical FID and is part of Core Web Vitals.
Definition and sourcesAn agreed interaction boundary between user and system or between components. It may mean a screen, API or programming contract; context determines meaning.
Definition and sourcesLinking pages within the same website. It helps users and crawlers discover content and should reflect topic relationships and navigation needs.
Definition and sourcesConnected devices collecting data or acting in the physical world. Security includes updates, device identity and access restrictions, not just connection encryption.
