üzenetküld

Üzenetküld is a Hungarian term that refers to the act of sending a message. In general usage, it denotes the process of transmitting content from a sender to a recipient. In computing and telecommunications, the term is used to describe the workflow that moves a message from creation to delivery across a channel, such as the internet or a mobile network. The word is a compound of üzenet (message) and küld (to send).

Contexts and forms: Message sending occurs across many platforms, including email, short message service (SMS), instant messaging, social media messaging, and in-app notifications. Message content can be plain text, rich text, multimedia attachments, or structured data such as JSON in application-level messaging.

Technical architecture: A typical send operation starts with a user interface or programmatic API that creates a message object, which is then handed to a backend service. The backend routes the message through transport protocols, stores metadata (timestamps, sender, recipient), and initiates delivery, possibly via a message queue.

Delivery semantics: Delivery can be asynchronous and may include retries, acknowledgments, and status notifications. Semantics can vary from at-most-once to exactly-once delivery, depending on the platform and guarantees offered by the underlying transport.

Security and privacy: Messages are commonly protected in transit with encryption protocols such as TLS, and some services offer end-to-end encryption. Access controls, authentication, anti-spam measures, and user privacy considerations are important aspects of message sending systems.

Standards and protocols: Email uses SMTP, while SMS may rely on SMPP or other gateway protocols. Instant messaging often uses XMPP, MQTT, or proprietary APIs. Push notifications rely on APNs (Apple) and FCM (Google). Many platforms implement customized, platform-specific send mechanisms.
