Andmeedastusstandardid (data transmission standards) are formal specifications that define how data is transmitted over a medium between devices and applications. They cover physical characteristics such as electrical signaling, connectors and cabling, as well as data encoding, framing, addressing, error detection, flow control, timing, and protocol rules. The aim is interoperability, reliability, efficiency, and safety across equipment and networks, enabling different systems to communicate effectively.

Standards are developed and maintained by international and regional bodies such as ISO/IEC, IEEE, ITU-T, and IETF, often through dedicated committees and working groups. Work proceeds through consensus, public review, and revision cycles, and the resulting documents may be published as formal standards or recommendations. Standards can specify both low‑level hardware interfaces and higher‑level communication protocols, covering layers from the physical and data link to network and transport, as well as data formats and interfaces.

Common examples include Ethernet (IEEE 802.3), Wi‑Fi (IEEE 802.11), USB (various USB 2.0/3.x specifications), Bluetooth (IEEE 802.15.1), PCIe and SATA for storage and interconnect, and network protocols like TCP/IP (RFCs), IPv6, and TLS. In multimedia and telecom, standards such as HDMI, patient-safe medical data interfaces, and mobile transmission standards defined by ITU‑T and 3GPP play major roles as well. These standards underpin interoperability across vendors, enable certification and market access, and shape the development of products and services.

The landscape evolves continually to support higher data rates, new media, and emerging technologies, requiring ongoing updates and new working groups to address future communication needs.
