Clear filtersTest-driven development
An approach where a test of expected behaviour precedes implementation, followed by refactoring. It does not mean writing arbitrary tests after completing a feature.
Definition and sourcesTether (USDT)
Tether USD₮, commonly USDT, is a token designed to track the dollar. Its issuer publishes reserve and redemption information. Issuer statements do not guarantee an unchanging market price or eliminate counterparty risk.
Definition and sourcesThird-party login
Signing in with an account held by another provider, such as Google. OpenID Connect confirms identity without sharing that account's password with the application. Data access depends on the integration and permissions.
Definition and sourcesTiki Wiki CMS Groupware
A platform combining wiki, content management and collaboration tools. Its broad scope requires organised permissions and limiting unnecessary modules.
Definition and sourcesTime to First Byte
Time until the first response byte arrives. It includes more than application execution, such as networking and connections, and does not indicate rendered content.
Definition and sourcesTime to live
A value limiting cached-data lifetime, such as a DNS record's. It does not guarantee simultaneous resolver refreshes; the term has other networking meanings too.
Definition and sourcesTime-based one-time password
A one-time code derived from a shared secret and time. It needs clock synchronisation; codes can be phished, so TOTP is not universally phishing-resistant.
Definition and sourcesTiny text
A colloquial term for extremely small text. Deliberately hiding keywords from users to manipulate rankings can violate search policies; ordinary footnotes simply need readability.
Definition and sourcesTLD (Top-Level Domain)
The final part of a domain name, such as .pl or .com. Categories include country-code and generic TLDs. An ending alone establishes neither owner trustworthiness nor improved search rankings.
Definition and sourcesTokens
Digital units governed by a network or contract's rules. They can represent rights, access or assets. Meaning and risk depend on the project; a token is not automatically a company share.
Definition and sourcesTopical authority
An industry term for recognised website expertise on a topic. It is not one public Google metric; accuracy, coverage and usefulness matter.
Definition and sourcesTraceroute
A tool showing responding hops along a packet route. Asterisks may mean filtering; the reverse path need not be identical.
Definition and sourcesTrailing slash
A final / in a URL path. URLs with and without it can identify different resources; websites should use consistent redirect policies.
Definition and sourcesTranspiler
A tool transforming source code into other source code, such as older syntax. It need not provide missing runtime functionality.
Definition and sourcesTransport Layer Security
A protocol protecting communication through encryption and endpoint authentication. It needs current versions and certificate checks and does not certify website honesty.
Definition and sourcesTrust Flow
A Majestic metric based on link relationships with selected trusted sources. It is a tool's measure rather than an official Google trust score.
Definition and sourcesTwo-factor authentication
Authentication using two different factor types, such as a password and a device. Two passwords are not two factors; phishing resistance depends on the method.
Definition and sourcesTypeScript
A language extending JavaScript with static typing. Type checks help before execution but do not replace validation of network input.
Definition and sourcesTYPO3
An open-source PHP CMS also used for complex websites and content structures. Deployment needs appropriate versions, extensions and maintenance expertise.
Definition and sourcesTypography
Designing and organising written text through typefaces, sizes, spacing and hierarchy. It affects readability and communication character. Typography concerns the whole text arrangement, not only font selection.
