Apache Kafka
A distributed event-streaming platform that stores and reads records in topics. Data can be processed again according to configured retention rules.
Definition and sourcesAPI (Application Programming Interface)
An interface defining how software can use another component's functions or data. It specifies available operations and communication rules. An API can belong to a local library; it need not operate over the internet.
Definition and sourcesApilo
A system integrating online sales operations, orders and sales channels. Synchronisation scope depends on available integrations and their configuration.
Definition and sourcesApplication
Software performing user tasks, such as document management. It may run in a browser, computer or phone; its interface and server service can be separate.
Definition and sourcesApplication performance monitoring
Monitoring application behaviour through latency, error and dependency measurements. APM supports diagnosis, but collecting metrics alone does not fix incidents.
Definition and sourcesArtificial intelligence
A field developing systems for recognition, prediction and content generation, among other tasks. It includes more than chatbots. This is the expanded name of AI; task performance does not establish consciousness or infallibility.
Definition and sourcesASP.NET
Microsoft's platform for web applications and services in the .NET ecosystem. ASP.NET Core differs from the older ASP.NET Framework, including platform support.
Definition and sourcesAssembly language
A low-level language describing instructions for a processor architecture. It is translated into machine code; no single instruction set covers all processors.
Definition and sourcesAttribution
Assigning conversion credit to marketing interactions. Different models and data coverage can produce different results for the same sale.
Definition and sourcesAuthenticated Received Chain
A mechanism preserving email authentication information across forwarding. ARC helps receivers evaluate intermediaries but does not replace SPF, DKIM or DMARC.
Definition and sourcesAutoresponder
A mechanism automatically replying to messages, such as during absence. Frequency and recipient limits help prevent reply loops and unnecessary disclosure.
Definition and sourcesAVIF
An image format using AV1 coding. It can reduce file size at good quality, but decoding support and variant-generation costs need consideration.
Definition and sourcesB2B (Business-to-Business)
A business relationship in which a company sells to another company. Examples include enterprise software and manufacturing supplies. B2B describes the customer, not a particular sales channel.
Definition and sourcesB2C (Business-to-Consumer)
A model in which a business sells goods or services to consumers. It includes online and offline transactions. The abbreviation identifies the customer type rather than the technology used.
Definition and sourcesBabel
Tools transforming JavaScript, including syntax compatible with older environments. Syntax transformation does not necessarily supply missing runtime APIs.
Definition and sourcesBack-end developer
A developer responsible for server-side application behaviour, including business logic, data access and APIs. Languages depend on the project. The role does not require mastery of every popular programming language.
Definition and sourcesBackbone.js
A JavaScript library organising interfaces through models, collections, views and events. It provides lightweight structure rather than a complete prescribed rendering framework.
Definition and sourcesBackend
The server-side portion responsible for logic, data and permissions. Browser interfaces communicate with it through requests.
Definition and sourcesBacklink
A link from another website to your page. It can help people discover content and provide a search signal. Context matters: buying links to manipulate rankings can breach a search engine's policies.
Definition and sourcesBacklink gap
A backlink comparison finding sites linking to competitors but not the analysed site. It identifies opportunities to assess, not links to copy automatically.
Definition and sourcesBacklink profile
A website's incoming links and their characteristics. Analysis considers sources, context and quality; referring-domain counts alone are insufficient.
Definition and sourcesBacklog
An ordered list of work needed to improve a product. In Scrum, the Product Backlog evolves with learning rather than being frozen initially.
Definition and sourcesBackup
A data copy intended for recovery after loss or corruption. Usefulness depends on freshness, separation and tested restoration, not merely a completion message.
