when do you use an ethernet crossover cable
Ethernet crossover cable An Ethernet crossover cable is a crossover cable for Ethernet used to connect computing devices together directly. It is most often used to connect two devices of the same type: e.g. two computers (via their network interface controllers) or two switches to each other. By contrast, patch cables or straight through cables are used to connect devices of different types, such as a computer to a network switch or Ethernet hub.
Emirates Air Line (cable car) The service, announced in July 2010 and estimated to cost £60,000,000; comprises a 1-kilometre (0.62 mi) gondola line that crosses the Thames from the Greenwich Peninsula to the Royal Victoria Dock, to the west of ExCeL London. Construction of the cable car began in August 2011.[10] The cable car is based on monocable detachable gondola (MDG) technology, a system which uses a single cable for both propulsion and support, used also on the metrocable in Medellín, Colombia. The MDG system is reportedly cheaper and quicker to install than a more complex three-cable system which would allow larger-capacity cars.[11]
