Embodiments of the present invention include network cables that include a number of inter-integrated circuit communication addressable components in the connector heads. In various embodiments, search methods and systems provide for response times and network traffic that are independent from the number of query terms, thereby producing constant run-time searches and bandwidth hits in a P2P network search implementation. The second frame is moveable, with respect to the first frame, between a raised position, where the transverse element provides a back support, and a lowered position where the transverse element provides a rung of a boarding ladder. When the third groove is reached, the cylindrical members are allowed to make only relative rotations without moving in the axial direction. The element may be electrically connected to and spaced away from a copper line of the metallization level by way of an electrical link passing through the barrier layer and including an electrically conductive material different from copper in direct contact with the copper line.
