The function of wires is to transport an electric signal from one point to another. There are various types of wires for all sorts of different uses, generally depending on the kind of signal they carry.
At the far ends of the wires connectors are fixed which also vary depending on the kind of signal the wire transports. The transportation of the electric signal by a wire must take place with as little distortion as possible. A wire is made up of conducting material, and the better its quality (which often means “more expensive”) the better its conductive qualities. Naturally there is no such thing as a conductor which gives no resistance whatsoever, therefore each wire has a tension drop at its far ends, which in other words means that there is a loss of signal which increases the longer the wire is. The loss of signal in a wire is measured in dB/m or dB/km (a 5m long wire which has a loss of 2 dB/m attenuates the signal passing through it by 10 dB).
