4tråds

4tråds is a term that can refer to several different concepts, often related to technology or communication. In some contexts, it signifies a four-wire system, a common setup in telecommunications and electrical engineering. This typically involves two wires for transmitting signals and two wires for receiving them, allowing for full-duplex communication where data can be sent and received simultaneously. This contrasts with two-wire systems, which are usually half-duplex, meaning transmission and reception cannot occur at the same time.

Another interpretation of 4tråds relates to a specific type of audio or video cable configuration. Such cables might contain four individual conductors or "strands" to carry different audio channels (like stereo left and right, plus separate channels for microphone input and output) or video signals. This allows for more complex signal routing and higher fidelity compared to simpler cable designs.

The term can also appear in discussions about network cables, particularly older Ethernet standards like 10BASE-T, which utilized four wires within a larger cable for transmitting and receiving data. While modern Ethernet standards use more wires, the historical context of four-wire configurations remains relevant. The precise meaning of 4tråds is therefore dependent on the specific technical field or application being discussed.
