Transmissionslogik

Transmissionslogik is a term used in telecommunications and computing to describe the set of rules, structures, and mechanisms that determine how data is prepared for transmission, transmitted, and interpreted at the receiving end. It includes framing and encoding, synchronization, error detection and correction, flow control, and channel access decisions. The aim is to ensure reliable and efficient communication despite noise, variable delay, and multiple competing transmissions.

In practice, transmission logic is implemented in protocols operating at the link and network layers, and in hardware such as modems and network interface cards. It governs how bits are arranged on a medium, how devices access a shared channel, how transmissions are timed, and how errors are signaled and recovered. Common transmission-logic strategies include ARQ (automatic repeat request) methods like stop-and-wait, go-back-N, and selective repeat, as well as multiplexing and scheduling approaches such as time-division, frequency-division, and code-division schemes. Channel-access mechanisms such as CSMA/CD, token passing, or polling determine when a device may transmit on a shared medium.

In digital storage and I/O, transmission logic covers sequencing, buffering, and flow control between controllers and storage devices or peripherals. Design considerations include reliability, latency, throughput, error probability, and power consumption, as well as the characteristics of the transmission medium.

Transmissionslogik intersects with related concepts such as transmission protocols, error-detection/correction codes, and network architecture, and evolves with advances in wireless, fiber, and data-center technologies.
