<h2id="ethernet">Ethernet</h2>
<p>Ethernet is a family of computer networking technologies working over WAN (Wide Area Network), LAN (Local Area Network) and MAN (Metropolitan Area Networks). The Internet Protocol is commonly carried out over ethernet, so it has become one of the key technologies that make up the Internet.</p>
<p>Ethernet was developed at Xerox PARC (Palo Alto Research Center) between 1973-1974. The idea was first documented in a memo written by Robert Metcalfe, who <aclass="outOfNetworkLink"name="outOfNetworkLink"href="https://www.youtube.com/watch?v=g5MezxMcRmk"target="_blank">named it</a> after the <ahref="please_to_foshan.html#theAether">luminiferous aether</a>, a substance that was once thought to exist as an "omnipresent, completely-passive medium for the propagation of electromagnetic waves."</p>
<p>While topology is the study of forms that are preserved under deformations, such as stretching, crumpling or bending (but not tearing or gluing), graphology is the study of diagrams that represent these forms in a 2-dimensional space. Often 3-dimensional topologies can be collapsed into <ahref="beetroot_to_ciao.html#sevenBridges">2-dimension graphology studies</a>.</p>
<p>GPS (Global Positioning Service) is a satellite radionavigation system owned by the United States government, and operated by their air force. The system uses a process of <ahref="wijnhaven_to_foshan.html#trilateration">trilateration</a>, whereby at least three satellites are needed to determine position.</p>
<p>As I walked from server to server, I began to notice lines. <ahref="beetroot_to_wijnhaven.html#contrails">Contrails</a> in the sky, <ahref="ciao_to_wijnhaven.html#tyre_tracks">tyre marks</a> on bicycle lanes, overhead <ahref="p_lions_es_to_wijnhaven.html#tram_lines">tram lines and their corresponding tracks</a>...<p>
