Routers which are boxes of circuit boards and microchips, which do the essential trade union movement of enjoin and redirecting packets along the network. Much smaller boxes of circuit boards and microchips called modems do the task of translation between the phone lines and the computer. The packe ts are all switched into a destination and r! eassembled by the destination computer. Todays Internet contains enough iterative and co-ordinated circuits simply to reroute the data if any portion of the network goes overthrow or gets overloaded.
